Fewer bearingreplacements and lessmaintenance

Plummer blockhousings have much to offerThe main benefit of split plummer block

housings is their easy installation;preassem-

bled shafts can be mounted in them. When

the housing bases are attached to the base

plate, it is then only necessary to place the

housing caps in position and to tighten the

attachment bolts to complete theinstallation.

Split plummer block housings available on

the market are mainly intended forself-align-

ing ball bearings, spherical rollerbearings and

CARB toroidal roller bearings of ISO Dimen-

sion Series 02, 03, 22, 23 and 32. They can

often be fitted with a number of different

seals. Many designs and variants of split

plummer block housings are available,making

the use of tailored housings unnecessary and

thus enabling cost-effective bearing arrange-

ments to bemade.

For many years SKF has been one ofthe

leading producers of split plummer block

housings –synonymous with operational

reliability, quality andversatility.

SNL plummer blockhousings have moretooffer

SKF has developed the SNL plummer block

housings to be the first choice for design,

quality and economy. This enablescustomers

to keep a stepahead.

SNLplummerblockhousingsenablethefull

service life potential of the incorporated bear-

ings to be exploited with less need for main-

tenance.This supports user’sefforts tofurther

reduce maintenance costs. Among other

characteristics, the housings are very stiff,

making them insensitive to uncontrolled and

excessive tightening of the attachmentbolts.

Anotherbenefit is thewiderangeofdifferent

typesof standard seals tobe fitted in theSNL

plummerblockhousings.

One basic design –many variantsSNL plummer block housings are primarily

intended for self-aligning ball bearings, spher-

ical roller bearings and CARB toroidal roller

bearings. The housings are designed on the

”building block” principle to enable a wider

choiceofbearingsandsealsaswellasavariety

ofmounting and lubrication methods.

Abuilding block system

The SKF assortment of SNL plummer block

housings can accommodate shafts ranging

from20to160mmindiameter.Thesehous-

ings, which allshare the same design features,

are available with a variety of seals. The

standard range also includes a number of

options, like tapped holes for grease fittings

and condition monitoring sensors, to create

an almost limitless combination of variants.

Housings are also available for bearings for

larger shaft diameters ( † page 103).

SNL plummer block housings are made

of high quality, grey cast iron to providehigh

tensile strength. For applications whereadd-

itional strength is required, housings made

of spheroidal graphite cast ironare available.

Several sealingoptions

AnimportantadvantageoftheSNLplummer

block housings is that they can be fitted with

a variety of seals. Standard SKF sealsinclude

four-lip seals,V-ringseals,feltseals,labyrinth

seals and heavy-duty taconite labyrinth seals

with a radial labyrinth and end covers. Other

standard seals are also available for SNL

housings, but the housing has to be modified

for the seal to be effective. These include oil

seals and heavy-duty taconite labyrinth seals

with an axiallabyrinth.

SNL plummer block housings are dimen-

sionally interchangeablewiththeearlierSNH

housings. Theirdimensions conform to

ISO113:1999.

Features andbenefits

The SKF assortment of SNL plummer block

housings is characterized by a number of

advantages, including high load carrying

capacity and machining quality. In addition,

SNL housings incorporate unique features

that are designed to improve theperformance

and increase the service life of yourapplication.

Stiffdesign

The housing base is reinforced with ribs and extra

material around the attachment holes to add strength

and prevent deformation of the base. Theattachment

bolts can be preloaded to locate the housing and

prevent deformation of the housing base andbore.

Excellent heatconduction

Additional ribs on the underside ofthe base improve

heat flow from the bearing outer ring to the support

surface. Bearings in an SNL housing run 5–10 %

cooler than the bearings in otherhousings.

Relubrication madesimple

Standard SNL housings have two tapped holes in the cap for the grease fitting. They are protected byplas-tic plugs. The location of the grease fitting is deter-mined by the bearing. If the bearing has a W33 groove, install the fitting in the middle of the housing. Otherwise, put the fitting in the other hole so that grease will enter the bearing from theside.

Caps and bases individuallymarked

The housing base and cap are matched duringman-

ufacture and are not interchangeable with the caps

and bases of other housings. To prevent any mis-

matches, a unique serial number is marked on both

the housing cap andbase.

Grease guidingsystem

When lubricating from the top, this feature

guides fresh grease from the fitting to theside

of the bearing. This applies in particular for

lubricating self-aligning ball bearings and

CARBbearings.

Dimples to locateaccessories

SNL housings have dimples cast into the housingcap

to show where condition monitoring sensors can be

mounted for maximumeffectiveness.

Simplemounting

To simplify mounting and make alignment more

accurate, lines indicating the centre of the boreand

the centre of the base are cast into thehousing.

Mounting instructions, included with each seal pack,

provide valuable installation tips.

High speedseal

The SKF four-lip, low friction seal was developed

specifically for SNL housings. This highly effective

seal, which can accommodate speeds up to 13m/s,

is easy to remove andinstall.

Bearing arrangementdesign

SNL plummer block housings are typically

used with self-aligning ball bearings, spher-

ical roller bearings or CARB toroidal roller

bearings fitted on straight or stepped shafts;

the bearings can be mounted on adapter or

withdrawal sleeves or directly on cylindrical

shaft seats. These housings can also be used

with other bearing types ifthey are within the

correct DimensionSeries.

1. Bearings on adapter sleeves on straight shafts

Advantages

• Drawn round bar (tolerance h9) canbe

used withoutmachining.

• Maximumshaftstrengthasthere isno

weakening by shoulders orreliefs.

• Bearings can be mounted at anyposition

on theshaft.• Mounting force, i.e. the force required to

drive thebearingonto thesleeve, is 40 %

lessthanwithothershaftsbecausethere

is onlyoneslidingsurface.

• Bearing radial clearance can beadjusted

(within limits) during mounting to meet

applicationdemands.

Applications

• Bearing arrangements for relatively long

shafts where more than two bearingsare

required forsupport.

• Bearing arrangements where machine

components are mounted usingwedging

or tensioning components that do not

require the shaft to bemachined.

• Bearing arrangements where the final

position of the bearing cannot beaccurately

determined.

Standard seals

An important advantage of SNL plummer

block housings is that they can be fitted with

different types of seals. Standard SKF seals

include split four-lip seals, V-ring seals, felt

seals, labyrinth seals and heavy-duty “taco-

nite” seals with a radial labyrinth. The seals

are easy to install and are suppliedseparately.

All thestandardseals,aswellastheseals

for use with oil lubrication, are shown in

table 1, with an overview of the seal type,

its design features and suitability forvarious

operating conditions. Detailedinformation

Four-lipseals

With shaft speeds continuously increasing,

there was a need for a sealing solution that

could accommodate higher speeds with the

same high level of performance that the SKF

double-lip seal could provide at lowerspeeds.

To meet that need, SKF developed arobust,

easy-to-mount four-lip seal ( † fig. 1) that

can accommodate peripheral speeds upto

13m/s.This four-lip seal ismadefromaspe-

cially formulated thermoplastic elastomer. It is

manufactured using a unique process that

improves the finish of the contact surfaces so

that there is less friction and heat generated

by the seal. These four-lip seals, which are

designed for grease lubrication, can accom-

modate speeds up to 13 m/s even if thehous-

ing uses a grease escape hole (suffix V). The

seals are split so that they can be installed

easily.

The permissible angular misalignment for

shaft diameters ≤ 100 mm is approximately

1°and approximately 0,5° for larger shafts.

The seal counterface on the shaft should be

ground and the surface roughness Ra should

not exceed 3,2 µm. The recommended shaft

tolerance is h9. The axial movement of the

shaft relative to the housing is not limited

when four-lip seals are used. Thepermissible

operating temperature range for the seal is

between –40 and +100 °C (–40 to +210°F).

The seals are available from size TSN 507 L

uptoandincludingsizeTSN532L.

Each package of four-lip seals contains two

seals. Consequently, when using an end cover,

one seal can be kept as a spare. Four-lip seals

are identified by the designation prefix TSN

followed by the size identification and thesuf-

fixL,e.g.TSN511L.

V-ring seals

V-ring seals ( † fig. 2) are two-piece seals

thatconsistofaV-ringandagalvanized,sheet

steelsealingwasher.Arubber lip,vulcanizedto

the sealing washer, fits into the seal groove in

the housing. The V-ring fits tight on the shaft

and seals axially against the washer. As it is

turning with the shaft, the V-ring acts as a

flinger. These very efficient seals are typically

used in difficult applications e.g. where there

are high speeds or rough finished shafts. They

can accommodate peripheral speeds in excess

of 7 m/s if the V-ring is prevented from mov-

ing or lifting from the shaft by a support ring.

Recommended dimensions for appropriate

support rings (for axial and radial location) are

provided in table3.

NOTE:Supportrings cannotbeusedforsizes

between 205 to 211 and 306 to 314 due to

limited space between the shaft and housing

shaftbore.

The permissible angular misalignmentfor

V-ring seals is approximately 1,5° fora

50 mm shaft decreasing to approximately 1°

for shaft diameters ≥ 150 mm. The axial

movement of the shaft relative to thehousing

is limited to ±1 mm for shaft diameters up to

65 mm, to approximately +/-1,2 mmfor

70-100 mm shaft diameters and to approxi-

mately +/-1,5 mm for larger shaftdiameters.

Each package of V-ring seals contains two

Felt ringseals

Feltring seals ( † fig. 3)aresimple,efficient

grease seals that can accommodate periph-

eral speeds up to 4 m/s. These seals can

accommodate higher speeds, butbeyond

4 m/s, a small gap forms between the feltand

shaft, transforming the contact seal into a

non-contact, gap-typeseal.

In applications where bearings aremount-

ed on a straight shaft with adapter sleeve,

split felt ringseals are typically used

( † fig. 3a). The felt is impregnated with oil.

To install these seals, a round rubber cord is

first insertedintothesealgroove in thehous-

ing. Then, with the felt inserted in the light

alloy half-rings, the half rings are installed in

the seal groove. The rubbercord prevents the

rings fromturning.

The permissible angular misalignmentfor

felt ring seals isapproximately0,5°.Theseal

counterface on the shaft should be ground

and the surface roughness Ra should not

exceed 3,2µm.

The axial movement of the shaftrelative to

the housing is not limited when felt seals are

used.

shaft with a cylindrical seat (sizes 205 to 218

inclusive), loose felt strips ( † fig. 3b) can be

used. The strips are 170 mm in length. They

should be cut to the right length and prior to

installation, they must be soaked in hot oil for

a few minutes. Then, they can be installed

directly intothesealgroove.The feltstripsare

designated FS170.

High temperatureapplicationsFor high operating temperatures, upto+250°C (480 °F), SKF graphited strips canbe

supplied. They should be cut to the right

length. They can be installed directly into the

sealgroove.

Seals made of fluoro rubber give offhaz-

ardous fumes when exposed to extreme

temperatures above 300 °C (570°F).

Therefore, review and follow the safety

recommendations mentioned in the sec-

tion “Seal materials” in the GeneralCata-

logue 6000, on page143.

Labyrinth seals

For applications where there are high speeds

and/or extreme temperatures, SKF recom-

mends using a labyrinth type seal ( † fig. 4).

The standard labyrinth type seal is called a

labyrinth ring. Labyrinth rings consist of a

metal ring with two steps arranged radially.

One step fits in the seal groove inthe housing

to form a gap type seal. The other step forms

a gap type seal with the outside of the hous-

ing. A hollow, silicone rubber cord supplied

with the seal holds the labyrinth ring in place

on theshaft.

The standard labyrinth seals can accom-

modate approximately 0,3°of angular mis-

alignment and operating temperatures rang-

ing from –50 to +200 °C (–60 to +390°F).

When labyrinth seals are used, axial move-

mentof theshaftrelative tothehousing isnot

limited. The recommended shaft tolerance is

h9.

Labyrinth rings are supplied singly. For

through-shaft applications, two rings should

be ordered. A labyrinth ring is identifiedby the

designation prefix TSN followed by the size

identification andthesuffixS,e.g.TSN511S.

Taconite heavy-dutyseals

Taconite is a very fine-grained mineral which

is extremely difficultto seal against. For bear-

ing arrangements which must operate under

very arduous conditions such as those

encountered in mining, labyrinth seals, which

can be relubricated, are recommended, as

grease enhances the sealing effect and

extends the serviceability of the seals. SKF

has developed different designs of these

heavy-duty seals (which can seal against

taconite, hence the name) that can be sup-

pliedforusewithSNLhousings.

One taconite seal design ( † fig. 5) is based

on a radial labyrinth seal and fits standard

housings. A V-ring seal mounted on the shaft

sealsagainstthenon-rotatingpartoftheseal,

which is inserted in the seal groove and pre-

vents contaminants from penetrating to the

bearing when the seal is relubricated. This

grease is supplied via a grease fitting in the

non-rotating part of the seal. Angular mis-

alignments of the shaft of up toapproximately

0,5°are possible. The permissible operating

temperature range for the seal isbetween

–40 and +100 °C (–40 to +210°F).

Theaxialmovementof theshaft relative to

the housing is limited for this typeof taconite

seal to±1mmfor shaft diametersupto

65 mm and to approximately ±1,2 mm for

sizes up to 100 mm and ±1,5 mm forlarger

shaft diameters. The recommended shaft

tolerance ish9.

These seals are supplied singly so that for

housings used on through shafts, itis neces-

sary to order two seals. The seal is identified

by the designation prefix TSN followed by

the size identification and the suffix ND, e.g.

TSN 511ND.

The second design of taconiteseal( † fig. 6) is based on a labyrinth seal with

the labyrinth stages arranged axially. The seal

is relubricated via lubrication holes and fit-

tings in the housing cap. The positions for the

holes are marked by dimples in the casting.

The permissible misalignment of the shaft

relative to the housing for this seal is approxi-

mately 0,5°. The operating temperaturerange

is from –40 to +250 °C (–40 to 480 °F). Axial

movement of the shaft relative to the housing

is also limited. The recommended shaft toler-

ance ish9.

Seals for oil lubrication

To retain oil in an SNL housing and prevent

leaks, SKF has developed a U-design labyrinth

seal ( † fig. 8). These seals, which require a

modified housing, consist of two parts: a sta-

tionary U-shaped plate that is bolted to the

housing, and a steel labyrinth ring that is

mounted on the shaft. Two hollow, silicone

rubber cords inserted between the loose fit-

ting labyrinth ring and shaft, keep thering

in place and prevent oil from escaping along

the shaft. To keep the two seal partstogether,

a retaining ring is mounted on the labyrinth

ring. These oil seals do not limit axial move-

mentof theshaftrelative tothehousing.The

recommended shaft tolerance for these seals

isg7,buth9isacceptable.

Modified SNL housings for oil lubrication

are supplied together with seals. Thehousings

with seals are identified by designation suffix

TURU, e.g. SNL 524 TURU. Special end cov-

ers, designation ASNH .. R, must be ordered

separately.

SNL.. TURU housings are prone to overfill-

ing with oil. This is due to the limited size of

the SNL sump. For this reason, it is very

important not to exceed the recommendedoil

level if leaksaretobeavoided( † table3 on

page30).

SONL housings for oil lubricationAs part of the SNL assortment, SKF has a full

line of SONL housings, specifically designed

foroil lubrication.Availableforshaftdiameters

ranging from 75 to 240 mm, these housings

are not as prone to overfilling as SNL hous-

ings. Other advantages of the SONL housing

include

• a 15 %larger oilsump (reservoir)

• cooling fins insidethecasting for improved

heatdissipation.

Special seals

For applications that require special seals,SKF

recommends ordering housings in the SNL 2

series rather than those in the 5 or 6 series.

Housings in the SNL 2 series have a larger

bore (Db) and can accommodate a wider

choice of sealdesigns.

Special sealsare notnormally suppliedby

SKF.Therefore, relevant seal groove dimen-

sions areprovidedin table4.

Endcovers

Housings mounted at the end of a shaft

shouldbefittedwithanendcoverthatfits into

thesealgroove( † fig. 9).Detailsof theper-

missible length of the shaft end can be found

in table 5. End covers, which are plastic, are

suitable for operating temperatures ranging

from –40 to +110 °C (–40 to +230°F).

For applications where temperatures

exceed 110 °C (230 °F), steel end covers

should be used. These can be cut from sheet

steel and placed in the seal groove. Use ahol-

low silicone rubber cord to hold the cover in

place. Seal groove dimensions are providedin

table4 onpage 21.

The standard plastic end cover isidentified

by the designation prefix ASNH followed by

the housing size identification,e.g.

ASNH511-609.

Locating rings

Thewidthofthebearing seatinSNLhousings

ismachinedinsuchwaythatitcanaccommo-

date bearings in the locating as well as in the

non-locatingposition.

The locating bearing, which locatesthe

shaft axially in both directions, must be

secured in the housing on both sideswith

a locating ring ( † fig. 10).

In most cases, the non-locating bearing is

free to move axially in the housing to accom-

modate thermal expansion of the shaft. How-

ever, CARB toroidal roller bearings are an

exception. These bearings accommodate axial

displacement internally and must thereforebe

secured in the housing, on both sides,with

a locatingring.Locating rings are identified by the desig-

nation prefix FRB followed by figures indicat-

ing the width/outside diameter inmillimetres,

e.g. FRB11.5/100.

Axial displacement using CARB toroidal roller bearings in SNL housings

Axial displacement reduces clearance in a

CARB bearing. As a result, the permissible

axial displacement depends on theclearance

in the bearing after mounting. Insufficient

radial clearance, combined with axial dis-

placement, could actually result in a preload

condition that causes the bearing to failpre-

maturely. See general catalogue for calcula-

tion of permissible axialdisplacement.

Even if clearance is sufficient, axial dis-

placement in a CARB bearing is limitedby the

distance the inner ring can move by any one

of thefollowing

• rollers startto be exposed on one side

of thebearing

• lock nut/locking washer fouls therollers

andcage

• type ofseal.

To avoid the rollers and cage assembly from

contacting the lock nut/ washer, bearings in

theC22Kseries, uptoandincludingsize22,

should be used with a special adapter sleeve

that has a narrow slot and a self-locking

KMFE nut. These sleeves are identifiedby the

suffixE,e.g. H311E( † fig. 11).

Forbearings in theC22KandC32Kseries

from size 24 and above, sleeves aresupplied

Application advice fortrouble-free operation

Condition monitoring is recommended for

SNL plummer blocks, particularly if they are

fitted to machines where bearing failures

would cause production stoppages. The early

recognition and trending of the degradationof

the machine and machine parts make it pos-

sible to analyse the root cause and to be able

to plan for corrective maintenance actions

before they areneeded.

Extensive monitoring experience and a

knowledge of the dynamic behaviour of

machines, machine components andbearings

where there is incipient damage enables SKF

to recommend two powerful signalprocessing

techniques that can be used for condition

monitoring.

Vibration velocity

The RMS (root mean square) of the velocity

ofvibrations inthefrequencyrange10Hzto

1kHzhasbeenusedwithgreatsuccessto

measure phenomena such as imbalance, mis-

alignment, resonance etc. High levels of vel-

ocity vibration can be generated by poor

machine conditions such as improper clear-

ances, imbalance, misalignment, weak foun-

dations, bent rotors, out-of-round, belt prob-

lems or damaged fan blades. The ISO

Standard 10816-1:1995 contains recom-

mendations for reference values for the RMS

velocity values measured on different classes

ofmachinesandmachineparts.Theserecom-

mendations provide a clear and quantifiable

measure for the changes inmachine condition.

Vibration velocity expressed as an overall RMS

value in the 10 Hz to 1 kHz frequency range

provides minimal information on defects in

rolling element bearings or gear mesh prob-

lems. These types of defect can now be easily

detected by enveloped acceleration in the

higher frequencyranges.

SKF Multilogonline systemIMx-T

SKF MachineCondition Transmitters(MCT)

SKF Micrologseries data collectors/ analysers

26

Envelopedacceleration

Bearing defects can be easily recognized by

measurement and analysis of an enveloped

acceleration signal of the higher frequencies

generated by the impact signals typical ofroll-

ing bearing defects and gear teeth problems.

This technique has proven to be extremely

reliable in the detection of incipient bearing

defects. The low frequencies generated by

imbalance, misalignment etc. are not meas-

ured and diagnosed within the enveloped

accelerationprocess.

• Condition monitoring and diagnosiswith

permanently installed monitoring systems

The SKF Multilog online system IMx-T is

the next generation of powerful, cost-

effective solutions for a variety of condition

monitoring applications. Together with

SKF @ptitude Observer software, Multilog

IMx-T provides a complete for early fault

detection and prevention, automaticadvice

for correcting existing or impendingcondi-

tions and advanced condition based main-

tenance to improve machine reliability,

availability andperformance.

SKF’s Machine Condition Transmitters

(MCT) deliver added value to essentialpro-

duction equipment by providing vital infor-

mation on bearing performance that helps

maximize potential machineutilization.

Highly cost-effective, using MCTs mean

potential problems can be spotted before

they deteriorate, so maintenance and

repair schedules can be forecast andpro-

duction arrangements can continue as

planned.

Each stand-alone monitoring devicemay

be permanently mounted onto a machine,

providing low-cost continuous monitoring

of specific machine, gear and bearing

performance parameters in pumps, fans,

motors and other general-purpose

machinery.

• Condition monitoring and diagnosiswith

a portable data collector andanalyser

SKF offers a range of portable condition

monitoring hardware, designed to assess

and report on temperature, oil condition,

speed, bearing condition, shaft alignment,

noise, vibration and more. Where a meas-

urementpointisdifficulttoaccess,perma-

nently installed sensors can be used.These

can be connected by cable to a connection

box accessible to the datacollector.

SNL housings prepared for condition monitoring

SNL housings have appropriate points for

sensors ( † fig. 1). Measuring point in posi-

tion 1 is perpendicular to the shaft, while

position 2 is parallel to the shaft. Both points

correspond to ISO 10816-1: 1995. The

measurementpointinposition3 isatapprox-

imately 45° to the shaft axis. For enveloped

acceleration, the angle of inclination of the

measuringpoint isofminor importance.

Measurement point in position 2 should be

used on SNL housings where the load acts

towardthebaseplate.Themeasuringpoint in

position 1 is intended for a housing that is

hung from its support or when the load acts

away from the baseplate.

Housingswithatappedhole forasensor in

position 3 can be supplied on request. These

housings are designated with the suffixSN.

For additional information aboutcondition

monitoring and the measurement tools and

systems available from SKF, contact the SKF

application engineeringservice.

Lubrication

SNL plummer blocks can accommodateeither

greaseoroil asalubricant,butgreaseispre-

ferred. For oil, SKFrecommends SONLhous-

ings. Whichever housing is used, thelubricant

should be selected based on the operating

conditions.Additionalinformationaboutlubri-

cant selection can be found in the SKF Gen-

eralCatalogue.

Grease lubrication

In most applications, the initial grease fill in

an SNL housing will adequately lubricatethe

bearing until the next plannedinspection.

However, certain operating conditions suchas

high speeds, high temperatures or heavy

loads may require more frequent relubrica-

tion. Table 1 provides guideline valuesfor

the initial grease fill. Depending on the

intended method of relubrication, thefollow-

ing grease fill percentages for the free space

in the housing arerecommended

• 40 %whenrelubricating fromtheside

of thebearing

• 20 %whenrelubricating through the

annulargrooveand lubricationholes

in thebearing outerring.

In either case, the free space in the bearing

should be completely filled with grease. For

relubrication quantities, more informationcan

be found in the SKF General Catalogue. Six

dimples cast into the top of the housing cap

indicates where holes can be drilled and

tapped to accommodate a grease fitting. One

dimple on each outer side of the central ridge

indicates a hole location to relubricate the

seal. SNL housings have, as standard, two

holes that have been drilled and tapped for a

greasefittingAH1/8-27PTF ( † fig. 2).On

a new housing, the holes are covered byplas-

ticplugs.Theseplugsshould bereplacedwith

the grease fitting and threaded plug supplied

with the housing. The hole in the middle of

the cap should be used to relubricate spheri-

cal roller bearings with a lubrication groove

and three holes in the outer ring, designation

suffixEorW33( † fig. 3).ForSNLhousings

from size 524 having an eye-bolt in centre of

housing thishole isdrilled inoneof theboss-

es ( † fig. 4). It should be noted that when

spherical roller bearings are to be lubricated

via the outer ring, the shaft should be rotat-

ing. If outer ring relubrication is not possible,

ard hole should contain the greasefitting

( † fig. 5) and the centre hole should be

plugged. If a different size grease fitting willbe

used, adapters that fit into the existing holes

are available ( † fig. 6), making rework

unnecessary.

To improve the effectiveness of relubrica-

tion in applications where V-rings are used,

mountanadditionalV-ring insidethehousing

on the side where grease isapplied. Doing this

forces grease to travel through the bearing to

reach the escape hole on the opposite side of

the housing. For this type of sealing arrange-

ment, SKF supplies a V-ring and a splash

plate that fits in the seal groove to cover a bit

more than the top half of thehousing

( † fig. 7).TheV-ring andsplash plateset is

identified by the designation prefix ASNAfol-

lowed by the housing size identification and

thesuffixV,e.g.ASNA511V.

In applications where bearings aremount-

ed on adapter sleeves, the grease should be

introduced from the opposite side of the lock

nut. If the housing is located at the end of a

shaft, grease should be applied at the point

closest to the endcover.

In applications where L or C design seals

are used, grease cannot escape via the seals.

Therefore,if frequentrelubrication isrequired,

SKF recommends using a grease escape hole

( † fig. 3 and 5). SNL housings with a grease

escape hole are identified by the suffix V, e.g.

SNL 511-609 V. Recommended dimensions

canbefound in table2 onpage 30.

Housing for oillubrication

Fig.9


Fig.8


SKF has developed a grease guiding system

forSNLhousings( † fig. 8).Thehousingcon-

tains an integrated flange that guideslubricant

from the grease fitting directly to the rolling

elements to provide a more efficient means of

relubrication. This design feature is available

onhousings fromsize511uptoandincluding

size532.

Oil lubrication

SNL housings can be used for oil lubrication

at relatively high speeds provided thehousing

has been modified. When using oil, it is

important to not overfill the sump and to use

specially developed U design seals ( † fig. 9)

or leaks may result. These seals, which are

described on page 20, are supplied with the

housing.

In order for these seals to be used, the

housing must be modified. SNL housings for

oil lubrication are supplied from SKF com-

plete with seals, ventilation plug and oil sight

glass. It is important not to exceed therecom-

mended oil level if leakage is to be avoided

( † table 3).

Mounting

SNL housings, together with the appropriate

SKF bearings, can create a robust,operation-

ally reliable system that will provide long

service life. However, if the system is to

achieve maximum service life, each compo-

nent must be mounted properly, using the

correcttools.

Bearings can be mounted either on a

tapered seat –typically an adaptersleeve

–or on a cylindricalseat.

Mounting bearings on a tapered seat When a bearing is mounted correctly on a

sleeve,therewillbeaninterferencefitbetween

theinner ring, sleeveandshaft.Thedegreeof

interference depends on how far the bearing

is driven up on the sleeve and can be deter-

mined either by measuring the reduction of

internal clearance in the bearing with a feeler

gauge or by measuring the drive-updistance.

Clearance reduction in a self-aligning ball

bearing with Normal radial internalclearance,

can be checked by turning and swiveling the

outer ring. If, when swiveling, the outer ring

provides slight resistance, it has a sufficient

degree of interference and the drive-up is

complete.

Another simple way to mount a self-align-

ingballbearingonanadaptersleeveis touse

aTMHN7 locknutspanner(available forbore

sizes up to 55 mm). These specially designed

spanners are marked with the angle through

which the lock nut shouldbe turned.

Small spherical roller and CARB toroidal

roller bearings can also be mounted on an

adaptersleevewithaTMHN7spanner.How-

ever, when mounting either of thesebearings,

donottousetheangleonthespanner,as it is

meant only for self-aligning ballbearings.

Appropriate angles can be found in thetables

in the chapters concerning spherical roller

bearings and CARB toroidal rollerbearings in

the SKF GeneralCatalogue.

To install larger spherical roller or CARB

toroidal roller bearings, either the clearance

reductionortheSKFDrive-up Methodshould

be used. When using a feeler gauge to meas-

ure clearance reduction, it is important that

the inner and outer rings of the bearing are

not displaced relative to eachother.

Detailsofthespanner locknutsetTMHN7,

several other mounting tools as well as the

SKF Drive-up Method can be found in the

catalogue MP3000 “SKF Maintenance and

Lubrication Products”, which will be sent on

Mounting bearingson a cylindrical seat

Bearings with a cylindrical bore are normally

mounted with an interference fit on the shaft.

Appropriateshafttolerancesshouldbeselected.

Small bearings may be mounted cold,driv-

en into position by applying light hammer

blows to a sleeve placed against the bearing

ring face.Theuseofamountingdollyenables

the mounting force to be appliedcentrally.

Theforcetomountbearings increasescon-

siderably with increasing bearing size. There-

fore, medium sized bearings should beheated

prior to mounting with an SKF electric induc-

tionheater.

Support surface for housing base

To provide long bearing service life, SKFrec-

ommends that all housing support surfaces

be finished to Ra ≤ 12,5 mm. The flatness

(planicity) tolerance should be to IT7. For

moderate demands, IT8 may besatisfactory.

Dowelpins

SNL housings are designed for loads acting

vertically to the housing base support. Ifthey

are to be subjected to moderate or heavy

loads, acting parallel to the basesupport,

a stop should be provided, or the housing

should be pinned to its support.Recommen-

dations for the position and size of the holes

to accommodate dowel pins are provided in

tables 4 and5.

Housings for four-bolt mounting

To attach SNL housings to T-shaped beams,

a variant with four oblong holes cast into the

mounting base can be supplied. Available

sizes are shown in table 5. These housings

are identified by the series designationFSNL,

e.g. FSNL511-609.It is also possible to drill four bolt holes in

the base of a standard SNL housing. Their

positions are indicated by cast dimples.Rec-

ommended dimensions are provided in

table 6 onpage 34. SNLhousings with four

drilled bolt holes can be supplied upon

Mounting SNL housings with four-lipsealsBefore starting installation work, thefollowing

instructions should be readcarefully.

1. Be sure that the work area is clean. Check

the dimensional and form accuracy of the

shaft seat. The shaft should be machined

to a h9/IT5 tolerance for adapter sleeve

mounting.

2. Check that the roughness of the support

surface is Ra ≤ 12,5 µm. The flatness

(planicity) tolerance should be to IT7.

Make sure that the mounting surface is

clean. If shims are used, the whole sur-

face must be covered by shims. The

mounting surface (frame) must be

designed to accommodate actual load,

vibrations andsettings.

3. Mount any components that are on the

shaft between the two SNLhousings.

4. If the bearing is mounted on an adapter

sleeve, determine its position relative to

the housing. For spherical roller bearings

with a lubrication groove and three holes

in the outer ring, SKF recommends using

the relubrication hole in the centre of the

housing. When relubrication from the

side of the bearing is required such as for

CARB toroidal roller bearings or self-

aligning ball bearings, the housing must

be positioned so that the grease fitting is

ontheoppositesideofthelocknut.When

a housing is located at the end of a shaft,

grease should be applied at the end cover

side.

8. Mount the second bearing and housing,

following steps 4 to7.

9. Lay the shaft with the two bearings in the

two housingbases.

10. For locating bearing arrangements and

arrangements with CARB toroidal roller

bearings, put in one locating ring oneach

side of thebearing.

11. Carefully align the two housing bases.

Vertical markings at the middle of the

side faces and ends of the housingbases

can facilitate this. Then, lightly tighten

the attachment bolts on bothhousings.

12. The remaining seal halves should be

inserted in the seal grooves in the two

housing caps and the space betweenthe

inner sealing lips filled withgrease.

13. Place the two housing caps over each

base and tighten the cap bolts (to join

cap and base) to the torque specified in

table 2 on page 52. The cap and base of

one housing are not interchangeablewith

those of other housings. The cap and

base of each housing should be checked

to see that they bear the same serial

number.

14. Check the alignment of the two housings

en theattachmentbolts in the twohous-

ing bases.Recommended tightening tor-

quesareprovidedin table2 onpage 52.

5. Position thehousingonthesupport sur-

6. Insert one seal half in each of thegrooves

in the housing base (If a stepped shaft is

used, first mount the distance ring). Fill

the space between the two inner sealing

lips with grease. If the housing is to be

used at the end of a shaft, insert an end

cover instead of a sealhalf.

7. Mount the bearing on the shaft, using an

adapter sleeve. Completely fill thebearing

with grease. The remainder of the rec-

ommended grease quantity should be

put inthe housing base at the sides

14. Apply a string of oil-resistant sealant, of

type Blue Silicone or equal, along the

outer contour-line and around the holes,

on the housing split surfaces. Then place

the two housing caps over each base and

tighten the cap bolts (to join cap and

base) to the torque specified in table 2on

page 52. The cap and base of one hous-

ing are not interchangeable with those of

otherhousings.Thecapandbaseofeach

housing should be checked to see that

they bear the same serialnumber.






16. Slide the seals against the housing side

surfaces. Mount the seal mounting

screws and tighten them. If an end cover

has been mounted fully tighten thescrew

on the external part ofthe end cover.

17. Mount the supplied ventilating plugs on

the top of the housings and, when oil

bath lubrication is used, mount the oil

level sight glasses. When circulating oil

lubrication is used, connect the oil inlet

and outlet pipes to thehousing.

Note:It is important that sealant,of type

Loctite or equal, is appliedonall threads

onthesuppliedaccessories.

18. When an oil bath lubrication is used, the

maximum and minimum levels shouldbe

indicated on the sight glass. Recom-

mended oil levels to be used for the

mounted bearings can be foundin

table 3 on page 30. The oil levels must

be read while the application is notoper-

ating.

Important: For oil bath lubrication, it is

important not to overfill the maximum

level as this can cause oil leakage from

the housings. For circulating oil, it is

important that the outletpipes can drain

the housing in a proper way to avoid

overfill of oilinside the housings.

19. Protect the housing assemblies from

negative pressure from surrounding

equipment.

20. One dayafter tightening the cap and

attachmentbolts,makesure that the

Designations and housingdata–general

Designations

SNL housing designations consist of a basic

designation that identifies the design,mate-

rial and size, followed by any supplementary

designations needed to identify featuresthat

differ from the standard design. A dash(–) in

the designation chart indicates that the fea-

tures belong to the standarddesign.

Load carryingability

SNL plummer block housings are intendedfor

loads acting vertically toward the base plate

(support). If loads acting in other directions

occur, check to be sure that themagnitude

ofthe load ispermissible for thehousing, for

the bolts joining the housing cap and base,

and for the attachmentbolts.

Load carrying ability of the housing

Guideline values for the breaking load Pof the

housing for various load directions are pro-

videdin table1.Thepermissible housing load

can be obtained from these values by applying

a selected safety factor that depends on the

operating conditions. In general engineering

in Europe, a safety factor of 6 is often used. It

is important fortheloadcarrying abilityof the

48

housing that thebolts joining thecapand

baseare tightened in accordancewith the

valuesprovidedin table2 onpage 52.

The axial load carrying capacity of the

housing isapproximately65%ofP180°.The

housing should be pinned to the support or

a stop should be provided in the directionof

the load, if one of following conditionsapply

• load angles between 55°and 120°exist• if theaxial loadsactingparallel to thebase

plate (support surface)exceed5 %ofP180°

shownin table1.

Note that P0°values are valid only when the

housing isnotsupported in themiddleof the

base plate i.e. the space between the rein-

forcement ribs in the baseplate.

The axial load carrying capacity of the

adapter sleeve must also be considered,see

General Catalogue for moreinformation.

Load carrying ability of cap bolts

SNLplummerblockhousingsaresuppliedwith8.8 strength cap bolts as standard. SNL hous-

ingsmadeofspheroidalgraphitecastironhave

10.9 strength cap bolts. The guideline values

fortheyieldpointQforthecapboltsarepro-

vided in table 2 on page 52 for various load

directionsaswellasthecorrespondingmaxi-

mum radial loadsF.

To avoid elastic separation of the cap and

base under load, and to resist gradualloosen-

ing over time, the cap bolts should be tight-

ened to the torque specifications listed in the

table. This is particularly important for hous-

ings that are subjected to cyclic loading and

dynamicimbalance.

Torque values for cap bolts are general

guidelines based on bolt manufacturers’ spe-

cifications and normal mounting practices

where external loads act on the housingbase.

For applications where external stationary

and/or rotating upward loads exist, consult

the SKF application engineeringservice.

Materials

Standard SNL housings are made of grey cast

iron. Sizes up to and including 28 comply with

EN-GJL-200 specifications. Sizes 30–32com-

ply with EN-GJL-250specifications.

For applications where extra strength and

resistance are required, SNL housings are

also available in spheroidal graphite cast iron

that comply with EN-GJS-400-18 specifica-

tions. Sizes range from 510-608 to 532 and

are dimensionally interchangeable withhous-

ings made from grey cast iron. For spheroidal

graphite cast iron, the values for P obtained

from table1 onpage 51 should bemultiplied

by a factor of1,8.

These housings are supplied as standard

withasolidbase,fromsize510-608,orwith

four oblong cast bolt holes in the base, from

size 511-609. Spheroidal graphite cast iron

housings are designated SSNLD for a solid

base, e.g. SSNLD 513-611 or FSNLD for

housings with four oblong cast holes,e.g.

FSNLD513-611.

Bearing seattolerance

SNL housings can be supplied with different

bearing seat tolerances. E.g. an interference

fit is advantageous for self-aligning bearing

systems (spherical roller bearing in the locat-

ing position and a CARB bearing in the non-

locating position) or if the application is sub-

jected to vibration. For additional information

contact the SKF application engineeringserv-

ice.

Paintingsystem

SNL plummer block housings arepaintedas standard in accordance with ISO12944-2:

1998, environmental Class C2. Black colour:

RAL9005.

Safe loads

For the American and Canadian markets, the

norm is to use safe loads instead of breaking

loads. The approximate safe loads fordifferent

load directions are provided in table 3 on

page 54. These guideline limits have been

established using accepted engineering prac-

tices with consideration given to safety, ulti-

mate tensile strength of the materials,and

working stresses to reflect a safety factor of 5

against base fracture, and a minimum factor

of 2 against cap bolt yield. The housings

should be pinned to the support or a stop

should be provided in the direction ofthe load,

if one of following conditionsapply

• load angles 55°and 120°exist• if the axial loads acting parallel to the base

plate(supportsurface)exceeds25 %of the

P180°valueshownin table3 onpage 54.

The maximum permissible axial load that can

be safely carried by the housing assembly

depends on various considerations inaddition

to the operational performance abilities ofthe

bearing. For a purely axial load (static or

dynamic), the permissible load on thehousing

should not exceed 65 %of P180° value shown

in table3 onpage 54.

High-performance, self-aligning standard rollingbearings

To match the high performance of the SNL

plummer block housings, SKF alsomanufac-

tures state-of-the-art self-aligning rolling

bearings:

• Self-aligning ballbearings.

• Spherical rollerbearings.

• CARB toroidal rollerbearings.

They are available in many sizes andseveral

designs.

The degree of bearing misalignment that

can be accommodated depends on thebear-

ing series and also on the seals used in the

SNLhousings.

Self-aligning ball bearings and spherical

roller bearings can be used for bothlocating

and non-locating bearing arrangements.At

non-locating positions, the bearing outerring

is free to move axially in its seating in the

housing bore. CARB toroidal roller bearings,

on the other hand, accommodate axial dis-

placements within the bearing and arealways

non-locating. It is common practice to com-

bine a CARB toroidal roller bearing on the

non-locating sidewithaspherical rollerbear-

ing or self-aligning ball bearing on the locat-

ingside.

Self-aligning ballbearings

Self-aligning ball bearings in the 12, 22, 13

and 23 series can be incorporated in SNL

plummer block housings. Sealed self-aligning

ball bearings in the 22-2RS1 series are also

appropriate, particularly where the surround-

ings inwhichtheplummerblocksaretooper-

ate are heavily contaminated. Self-aligning

ball bearings are available with a taperedbore

for mounting on adapter sleeves or with a

cylindricalbore.

Spherical rollerbearings

Spherical rollerbearings in the222,232,213

and 223 series can be incorporated in SNL

plummer block housings. Spherical roller

bearings are available with a tapered bore for

mounting on adapter or withdrawal sleeves,

or with a cylindrical bore. Sealed spherical

roller bearings in the 22, 32 and 23 Dimen-

sion Series can alsobe incorporated.

CARB toroidal roller bearings

CARBtoroidalrollerbearings in theC22,C 23 and C 32 series can be incorporatedin

SNL plummer blockhousings.

Although available in a caged as well as a

full complement version, itis normally recom-

mended that caged bearings be used in SNL

housings. CARB toroidal roller bearings are

available with a tapered bore for mounting on

an adapter sleeve or a withdrawal sleeve, as

well as with a cylindricalbore.

98

For easy mounting –adapter andwithdrawal sleeves

Generally, bearings with a tapered bore that

are incorporated in SNL plummer blockhous-

ings are mounted on straight or stepped

shafts by means of an adapter sleeve or, with

a withdrawal sleeve on stepped shaftsonly.

SKFmanufactures these sleeves inappro-

priatesizes for the rangeofbearings thatcan

beused in SNLhousings.

Adapter sleeves are more popular than

withdrawal sleeves as they are moreversatile

and easier tomount.

Withdrawal sleeves

These are also slotted sleeves with a tapered

outside diameter. The sizes used with bear-

ings for SNL housings have an externaltaper

of 1:12. Their dimensions are in accordance

with ISO2982-1:1995.

Bearings on withdrawal sleeves must be

mounted against a fixed abutment, e.g. a

shaftshoulder.Thewithdrawalsleevemustbe

secured in position after it has been pressed

into the bearing bore by a lock nut or end

plate on the shaft. The nuts are not supplied

with thesleeves.

These are slotted sleeves with a taperedout-

side diameter. The sizes used with bearings

for SNL housings have an external taper of

1:12 and are supplied complete with locknut

and locking washer. Their dimensions are in

accordance with ISO2982-1:1995.

When using adapter sleeves on straight

shafts, it ispossible tolocatethebearing at

any position on the shaft and no additional

axial location isrequired.

Other products

Locknuts

SKF lock nuts, also referred to as shaft nuts,

are available in several designs to axially

locate bearings on shaft ends. The most pop-

ular are those in the KM, KML and HM series.

These nuts have four or eight equally spaced

slots in theoutsidediameterandare lockedin

position with locking washers or locking clips

engaging a groove in the shaft. The nut

dimensions are in accordancewith

ISO 2982-2:1995, as are the dimensionsofthe locking washers in the MB andMBLseries

and locking clips in the MSseries.

Other lock nuts produced by SKFinclude

those in the KMT, KMTA, KMK and KMFE

series and do not require a groove in the

shaft.

Lubricating greases for bearings

Lubrication is a necessity for proper bearing

performance. Grease is normally used for

applications involving SNL plummer blocks.

SKF has put considerable effort into estab-

lishing a range of high-quality greases forball

and roller bearinglubrication.

The SKF SYSTEM 24 automatic lubricator

can also be used with SNL plummer block

housings. An adapter can be fitted to the

standard drilled and tapped hole in the hous-

ing cap. It should be remembered thatsurplus

grease should be able to leave the housing

( † section “Grease lubrication” on pages 28

and29).

Most of these housings are designed to take

self-aligning bearings, and the rangeextends

to shaft diameters up to andincluding

1 800 mm. Housings are available for oil

lubrication as well as grease lubrication and

also for bearings with a cylindrical ortapered

bore, mounted on adapter or withdrawal

sleeves.Straightorsteppedshaftscanbe

Condition monitoring equipmentThe goals of condition monitoring are tomax-

imize the time that the machine is correctly

functioning and to minimize the number of

breakdowns, thereby significantly reducing

operating downtime and maintenancecosts.

To achieve this, it is recommended that the

bearing and machine condition be monitored

either periodically or continuously. Condition

monitoring enables incipient bearing damage

to be detected and evaluated, so that bearing

replacement can be scheduled for a time

when the machine is not in operation, thus

avoiding unplanned stoppages. Applied to all

machinery (not just sensitive or problematic

machines), condition monitoring improves

machinery operation to an optimum level,

often exceeding the original equipmentspeci-

fications.

SKF provides a comprehensive range of

condition monitoring equipment tomeasure

allimportant parameters. These include

• temperature

• speed

• noise

• oilcondition

• shaftalignment

• vibration

• bearingcondition.

The range includes lightweight,handheld

devices for manual use as well as complex

continuous monitoring systems for fixed

installations in connection with preventive

maintenance.

One example is the MARLIN I-Pro data

manager, which is a rugged, high perform-

ance data collector that enables plant oper-

ations personnel to quickly and easily collect,

store and analyze overall machine vibration,

process and inspection data. The unit enables

trending, comparison with previous readings,

alarm alerts and more. A “user notes” feature

allows an operator to immediately record

detailed observations of troublesome

machine conditions or questionablemeasure-

ments.

Evolving by-wiretechnology

SKF has a unique expertise in the fast-growing by-

wire technology, from fly-by-wire, to drive-by-wire,

to work-by-wire. SKF pioneered practical fly-by-

wire technology and is a close working partner with

all aerospace industry leaders. Asan example, virtu-

ally all aircraft of the Airbus design use SKF by-wire

systems for cockpit flightcontrol.

SKF – theknowledge engineering company

From the company that invented the self-

aligning ball bearing more than 100 years

ago, SKF has evolved into a knowledge engin-

eering company that is able to draw on five

technology platforms to create unique solu-

tions for its customers. These platforms

include bearings, bearing units and seals, of

course, but extend to other areas including:

lubricants and lubrication systems, critical for

long bearing life in many applications; mecha-

tronics that combinemechanical andelectron-

ics knowledge into systems for more effective

linear motion and sensorized solutions; and

a full range of services, from design and logis-

tics support to condition monitoring and reli-

ability systems.

Though the scope has broadened, SKF

continues to maintain the world’s leadership

in the design, manufacture and marketing of

rolling bearings, as well as complementary

products such as radial seals. SKF also holds

an increasingly important position in the mar-

ket for linear motion products, high-precision

aerospace bearings, machine tool spindles

and plant maintenanceservices.

Developing a cleaner cleanerThe electric motor and its bearings are the heart of many householdappliances.

SKF works closely with appliance manufacturers to improve their products’ per-

formance, cut costs, reduce weight, and reduce energy consumption. A recent

example of this cooperation is a new generation of vacuum cleaners with sub-

stantially more suction. SKF knowledge in the area of small bearing technology

is also applied to manufacturers of power tools and officeequipment.

Harnessing wind power

The growing industry of wind-generated electric power provides a source of

clean, green electricity. SKF is working closely with global industry leaders to

develop efficient and trouble-free turbines, providing a wide range of large, highly

specialized bearings and condition monitoring systems to extend equipment life

of wind farms located in even the most remote and inhospitable environments.

Working in extreme environmentsIn frigid winters, especially in northern countries, extreme sub-zero tempera-

tures can cause bearings in railway axleboxes to seize due to lubrication starva-

tion. SKF created a new family of synthetic lubricants formulated to retain their

lubrication viscosity even at these extreme temperatures. SKF knowledge enables

manufacturers and end user customers to overcome the performance issues

resulting from extreme temperatures, whether hot or cold. For example, SKF

products are at work in diverse environments such as baking ovens and instant

freezing in food processingplants.

Maintaining a 350 km/h R&D labIn addition to SKF’s renowned research and development facilities in Europe and

the United States, Formula One car racing provides a unique environment for

SKF to push the limits of bearing technology. For over 60 years, SKF products,

engineering and knowledge have helped make Scuderia Ferrari a formidable

force in F1 racing. (The average racing Ferrari utilizes around 150 SKF compo-

nents.) Lessons learned here are applied to the products we provide to automak-

ers and the aftermarketworldwide.

Delivering Asset Efficiency OptimizationThrough SKF Reliability Systems, SKF provides a comprehensive range of asset

efficiency products and services, from condition monitoring hardware and soft-

ware to maintenance strategies, engineering assistance and machine reliability

programmes. To optimize efficiency and boost productivity, some industrial facil-

ities opt for an Integrated Maintenance Solution, in which SKF delivers all ser-

vices under one fixed-fee, performance-basedcontract.

Planning for sustainable growthBy their very nature, bearings make a positive contribution to the natural envir-

onment, enabling machinery to operate more efficiently, consume less power,

and require less lubrication. By raising the performance bar for our own prod-

ucts, SKF is enabling a new generation of high-efficiency products and equip-

ment. With an eye to the future and the world we will leave to our children, the

SKF Group policy on environment, health and safety, as well asthe manufactur-

ing techniques, are planned and implemented to help protect and preserve the

earth’s limited natural resources. We remain committed to sustainable, environ-

mentally responsiblegrowth.
