DesignsA single row deep groove ball bearing withfilling slots has a filling slot in both the inner
and outer ring (
fig ) enabling more andlarger balls to be incorporated than in stand-ard deep groove ball bearings. Filling slotbearings have a higher radial load carryingcapacity than bearings without filling slots,but their axial load carrying capacity issmall. They are also unable to operateat such high speeds as bearings withoutfilling slots.
The standard assortment of SKF deepgroove ball bearings with filling slots com-
prises:
basic design open bearings, shielded bearings, bearings with a snap ring groove.
Basic design bearingsBasic design bearings with filling slots areopen. Those bearings that are also pro-duced in shielded version may have seal re-cesses in the outer ring, for manufacturing
reasons ( fig ).
Shielded bearingsSKF deep groove ball bearings with fillingslots are available with shields on one orboth sides, designation suffixes Z or 2Z. Theshield forms a narrow gap to the inner ringshoulder ( fig ).
Bearings up to and including sizes 217and 314 are filled with a high-quality NLGIclass 2 polyurea base grease, that can be
used at temperatures between 30 and+150 C. The base oil viscosity is 115 mm2/sat 40 C and 12,2 mm2/s at 100 C.
Larger bearings are supplied with a high-quality NLGI class 3 lithium base grease, thatcan be used at temperatures between 30and +120 C. The base oil viscosity is 74mm2/s at 40 C and 8,5 mm2/s at 100 C.
The quantity of grease fills some 25 to 35 %of the free space in the bearing. The bearingsare lubricated for life and are maintenance-
free. They should therefore not be washedor heated above 80 C before mounting.

Because stainless steel deep groove ballbearings are often used in food processingmachines, the bearings can be deliveredwith a special non-toxic grease, designation
suffix VT378. This grease
fulfils the requirements of the Guidelinesof section 21 CFR 178.3570of the FDA(US Food and Drug Administration) regu-lations and
is approved by the USDA (United StatesDepartment of Agriculture) for catelory H1use (occasional contact with food stuffs).
Please check availability of bearings with
non-toxic grease before ordering.
Bearings with shields
Bearing with shields, designation suffix 2Z( fig ), have shields made of stainlesssteel. The shields form a sealing gap withthe land of the bearing inner ring shoulderand allow high temperatures and speeds.Bearings fitted with shields are primarilyintended for applications where the inner
ring rotates. If the outer ring rotates, there isa risk of the grease leaking from the bearingat elevated speeds.
Bearings with seals
Bearings with contact seals, designationsuffix 2RS1 ( fig ), have seals made ofan oil and wear resistant acrylonitrile buta-
3
2
diene rubber (NBR) with a sheet metal re-inforcement. The permissible operatingtemperature range for the seals is 40 to+100 C and up to+120 C for brief periods.
Contact seals run with their seal lip on theland of the bearing inner ring shoulder. Theseals are fitted with their external edge in therecesses at the outer ring and seal tightly.
Under extreme operating conditions, e.g.at high speeds or high temperatures, greasemay leak from bearings fitted with seals. Forbearing arrangements where this would beundesirable, special steps must be taken atthe design stage. Please consult the SKFengineering application service.
Bearing data generalDimensionsThe boundary dimensions of stainless steeldeep groove ball bearings are in accordancewith ISO 15:1998.
TolerancesSKF stainless steel deep groove ball bearings
are manufactured to Normal tolerances. Thevalues for Normal tolerances correspond toISO 492:2002 and can be found in tableon page 125.

Internal clearanceSKF stainless steel deep groove ball bear-ings are produced as standard with Normalradial internal clearance. The values for the
internal clearance are in accordance withISO 5753:1991 and will be found in tableon page 297. The clearance limits are validbefore mounting under zero measuring load.
MaterialsThe bearing rings and balls are producedfrom stainless steel X65Cr13 and the shieldsand cages are made of stainless steelX5CrNi18-10, according to ISO 683-17:1999.
MisalignmentSingle row stainless steel deep groove ballbearings have only limited ability to accom-modate misalignment. The permissible an-gular misalignment between inner and outerrings, which will not produce inadmissiblyhigh additional stresses in the bearing, de-pends on the radial internal clearance of thebearing in operation, bearing size, the internaldesign and the forces and moments actingon the bearing. Because of the complex rela-
tionship between these factors, no generallyapplicable specific values can be given.Depending on the various influences of thefactors, the permissible angular misalignmentlies between 2 and 10 minutes of arc. Anygreater misalignment will result in increasednoise in operation and decrease bearingservice life.
3
CagesDepending on the bearing series and size,SKF stainless steel deep groove ball bear-ings are supplied with one of the following
stainless steel cages (
fig ) as standard:
pressed snap-type sheet steel cage (a) ribbon-type cage of steel sheet (b) riveted cage of steel sheet (c)
For bearings with injection mouldedpolyamide 6,6 cage availability should bechecked prior to ordering.
Minimum load
In order to provide satisfactory operation,stainless steel deep groove ball bearings,like all ball and roller bearings, must alwaysbe subjected to a given minimum load, par-ticularly if they are to operate at high speedsor are subjected to high accelerations orrapid changes in the direction of load. Undersuch condition the inertia forces of the ballsand cage, and the friction in the lubricant, canhave a determental influence on the rollingconditions in the bearing arrangement and
may cause damaging sliding movements tooccur between the balls and raceways.
The requisite minimum radial load to beapplied to stainless steel deep groove ballbearings can be estimated using
n dmFrm = kr ( )2/3

1 000 100
where

SKF double row deep groove ball bearings( fig ) correspond in design to single rowdeep groove ball bearings. They have deepuninterrupted raceways and high conformity
between the balls and raceways. They areable to carry axial loads acting in both direc-tions in addition to radial loads.
Double row deep groove ball bearings arevery suitable for bearing arrangementswhere the load carrying capacity of a singlerow bearing is inadequate. For the sameoutside and bore diameters, double rowbearings are slightly wider than single rowbearings but have considerably higher loadcarrying capacity than single row bearings
in the 62 and 63 series.
1Bearing data generalDimensionsThe boundary dimensions of SKF double row
deep groove ball bearings are in accordancewith ISO 15:1998.
TolerancesSKF double row deep groove ball bearingsare produced to Normal tolerances. Thevalues for tolerances correspond to ISO492:2002 and can be found in table onpage 125.
Internal clearance
SKF double row deep groove ball bearingshave Normal radial internal clearance asstandard. The clearance limits are as speci-fied in ISO 5753:1991 and can be found intable on page 297.
MisalignmentMisalignment of the inner ring relative to theouter ring of a double row deep groove ballbearing can only be accommodated byforce, which leads to increased ball loads
and cage forces and a reduction in bearingservice life. For this reason, the maximumpermissible angular misalignment is twominutes of arc. Any misalignment of thebearing rings will result in increased noiseduring operation.
CagesSKF double row deep groove ball bearingsare fitted with two glass fibre reinforced poly-amide 6,6 cages ( fig ), designation
suffix TN9.
Note:Double row deep groove ball bearings withpolyamide 6,6 cages can be operated attemperatures up to +120 C. The lubricantsgenerally used for rolling bearings do nothave a detrimental effect on cage properties,with the exception of a few synthetic oils andgreases with a synthetic oil base, and lubri-cants containing a high proportion of EP
additives when used at high temperatures.For detailed information regarding the
temperature resistance and the applicabilityof cages, please refer to the section Cagematerials, starting on page 140.

Minimum loadIn order to obtain satisfactory operation,double row deep groove ball bearings, likeall ball and roller bearings, must be subjected
to a given minimum load, particularly if theyare to operate at high speeds or are subjectedto high accelerations or rapid changes in thedirection of load. Under such conditions theinertia forces of the balls and cages, and thefriction in the lubricant, can have a detrimentaleffect on the rolling conditions in the bearingarrangement and may cause damagingsliding movements to occur between theballs and raceways.
The requisite minimum load to be applied
to double row deep groove ball bearings canbe estimated using
n dmFrm = kr ( )2/3
( )2
1 000 100
whereFrm = minimum radial load, kNkr = minimum radial load factor
( product table)
= oil viscosity at operatingtemperature, mm2/s
n = rotational speed, r/mindm = bearing mean diameter
= 0,5 (d + D), mm
When starting up at low temperatures orwhen the lubricant is highly viscous, evengreater minimum loads may be required.The weight of the components supported bythe bearing, together with external forces,
generally exceeds the requisite minimumload. If this is not the case, the double rowdeep groove ball bearings must be sub-jected to additional radial load.
Axial load carrying capacityIf double row deep groove ball bearings aresubjected to a purely axial load, this axialload should generally not exceed the valueof 0,5 C0. Excessive axial loads can lead toa substantial reduction in bearing life.
Equivalent dynamic bearing loadFor dynamically loaded double row deepgroove ball bearings
P = Fr when Fa/Fr eP = 0,56 Fr + YFa when Fa/Fr > e
The factors e and Y depend on the relation-ship f0 Fa/C0, where f0 is a calculation factor( product table), Fa the axial component ofthe load and C0 the basic static loadrating.
If the bearings are mounted with the usualfits (shaft tolerance j5 or k5, depending on theshaft diameter, and housing bore tolerance
J7) the values for e and Y given in tablecan be used to calculate the equivalent load.
Equivalent static bearing loadFor statically loaded double row deepgroove ball bearings
P0 = 0,6 Fr + 0,5 Fa
If P0 < Fr, P0 = Fr should be used.

The permissible static load for a cam rolleris determined by the smaller of the values ofF0r and C0. If requirements regarding smoothrunning are below normal, the static load
may exceed C0 but should never exceed themaximum permissible static radial load F0r.
Axial load carrying capacityCam rollers are intended for predominantlyradial loads. If axial loads act on the outerring, e.g. as produced when the cam rollerruns against a guide flange, they will pro-duce tilting moments in the cam roller andthe service life may be reduced as a con-sequence.
Design of associatedcomponents
PinsWith few exceptions, cam rollers operateunder conditions of stationary inner ringload. If easy displacement of the inner ringis required under such conditions, the pin orshaft should be machined to tolerance g6.If, for some reason, a tighter fit is required,then the pin or shaft should be machined totolerance j6.
For applications where cam rollers aresubjected to higher axial loads, SKF recom-
mends supporting the inner ring of the camroller over its entire side face ( fig ). Thediameter of the supporting surface shouldbe the same as the face diameter d1 of theinner ring ( product table, page 402).
Guide flangesFor rails or cams with guide flanges ( fig ),the recommended flange height ha shouldnot exceed
ha = 0,5 (D D1)
This helps to avoid damage to the sealsfitted in the outer ring. The values for theouter ring diameters D and D1 are listed inthe product table.
LubricationSKF single row cam rollers are greased for
life and cannot be relubricated. They arefilled with a lithium base grease of consist-ency 3 to the NLGI Scale with good rustinhibiting properties and an operating tem-perature range of 30 to +120 C. The baseoil viscosity is 74 mm2/s at 40 C and8,5 mm2/s at 100 C.

Angular contact ball bearings have racewaysin the inner and outer rings that are displacedwith respect to each other in the direction ofthe bearing axis. This means that they are de-
signed to accommodate combined loads, i.e.simultaneously acting radial and axial loads.The axial load carrying capacity of angular
contact ball bearings increases with increas-ing contact angle. The contact angle is de-fined as the angle between the line joining thepoints of contact of the ball and the racewaysin the radial plane, along which the load istransmitted from one raceway to another,and a line perpendicular to the bearing axis.
SKF angular contact ball bearings are pro-
duced in a wide variety of designs and sizes.Those commonly used in general engineer-ing are:
single row angular contact ball bearings( fig ),
double row angular contact ball bearings( fig ),
four-point contact ball bearings ( fig ), double row cam rollers ( fig ).
Detailed information on these bearings andcam rollers belonging to the SKF standardassortment are given on the following pages.For other SKF angular contact ball bearingse.g. high-precision angular contact ballbearings, fixed section bearings, slewingbearings or hub units please refer to thesection Other SKF products, starting onpage 1077.

DesignsSingle row angular contact ball bearingscan accommodate axial loads acting in one
direction only. The bearing is normallyadjusted against a second bearing.The standard assortment of SKF angular
contact ball bearings comprises bearings inthe 72 B and 73 B series. Two versions areavailable for different purposes:
bearings for universal matching in sets or basic design bearings (not universally
matchable) for arrangements with singlebearings.
The bearings have a 40 contact angle( fig ) and therefore support heavy axialloads. They are non-separable and the bear-ing rings have one high and one low shoulder.The low shoulder enables a large number ofballs to be incorporated in the bearing, thusgiving the bearing a relatively high loadcarrying capacity.
In addition, SKF single row angular con-tact ball bearings are available in many other
dimension series, designs, and sizes. Forfurther information on these bearings, consultthe SKF Interactive Engineering Catalogueon CD-ROM or online at www.skf.com.
Bearings for universal matchingThe bearings for universal matching are spe-cifically manufactured so that when mountedin random order, but immediately adjacentto each other, a given internal clearance orpreload and/or an even load distribution will
be obtained without the use of shims orsimilar devices. Universally matchable bear-ings carry a designation suffix to indicate theinternal clearance (CA, CB, CC) or preload(GA, GB, GC).
When ordering, it is necessary to state thenumber of individual bearings required andnot the number of sets.
Paired mounting ( fig ) is used whenthe load carrying capacity of a single bearingis inadequate (tandem arrangement) or when
combined or axial loads act in both directions(back-to-back and face-to-face arrange-ments).

When arranged in tandem (a) the loadlines are parallel and the radial and axialloads are equally shared by the bearings.However, the bearing set can only accommo-
date axial loads acting in one direction. Ifaxial loads act in the opposite direction, or ifcombined loads are present, a third bearingadjusted against the tandem pair must beadded.
The load lines of bearings arranged back-to-back (b) diverge towards the bearing axis.Axial loads acting in both directions can beaccommodated, but only by one bearing ineach direction. Bearings mounted back-to-back provide a relatively stiff bearing arrange-
ment that can also accommodate tiltingmoments.
The load lines of bearings mounted face-to-face (c) converge towards the bearingaxis. Axial loads acting in both directions canbe accommodated, but only by one bearingin each direction. This arrangement is not asstiff as the back-to-back arrangement and isless suitable for the accommodation of tilt-ing moments.
Basic design bearingsBasic design single row angular contactball bearings are intended for arrangementswhere only one bearing is used at each bear-ing position. They have Normal tolerancesconcerning bearing width and standout ofthe rings. Therefore, they are not suitable formounting directly adjacent to each other.

DimensionsThe boundary dimensions of SKF single rowangular contact ball bearings are in accord-ance with ISO 15:1998.
TolerancesBasic design SKF single row angular con-tact ball bearings for single mounting areproduced to Normal tolerances. Standarddesign universally matchable bearings aremanufactured to better than Normal
tolerances.SKF Explorer angular contact ball bearings
are manufactured only as bearings for univer-sal matching with P6 dimensional accuracyand P5 running accuracy.
The values for tolerances correspond toISO 492:2002 and can be found in tablesto , starting on page 125.5

Internal clearance and preloadInternal clearance in single row angularcontact ball bearings is only obtained aftermounting and is dependent on adjustment
against a second bearing, which providesaxial location in the opposite direction.SKF universally matchable bearings are
produced in three different clearance andpreload classes each. The classes forbearing sets with clearance are:
CA small axial clearance, CB Normal axial clearance (standard), CC large axial clearance.
Bearings with clearance class CB are stand-ard. The availability of bearings with otherclearance classes can be obtained frommatrix on page 417. SKF universallymatchable bearings with clearance can becombined in sets of any number of bearings.
The classes for bearing sets with preloadare:
GA light preload (standard), GB moderate preload,
GC heavy preload.
Bearings to GA class preload are standard(matrix on page 417). Bearings withpreload can only be paired in sets of twobearings, in contrast to the SKF universallymatchable bearings with clearance, asotherwise the preload would increase.

MisalignmentSingle row angular contact ball bearingshave only limited ability to accommodatemisalignment. The permissible misalignment
of the shaft relative to the housing that willnot produce inadmissibly high additionalforces depends on the operating clearancein the bearing, bearing size, internal designand the forces and moments acting on thebearing. Because of the complex relationshipbetween the influencing factors, it is notpossible to quote any values that areuniversally valid.
For bearings mounted in sets, particularlythose with small axial internal clearance
mounted in a back-to-back arrangement,misalignment can only be accommodatedby increased ball loads, which will create cagestresses and reduce bearing service life. Anymisalignment of the bearing rings will alsolead to increased running noise.
Influence of operating temperatureon bearing materialSKF angular contact ball bearings undergoa special heat treatment. When equipped
with a steel or brass cage, they can operateat temperatures of up to +150 C.
CagesDepending on size and series, SKF single rowangular contact ball bearings are equippedas standard with one of the cages describedbelow and shown in fig . The availableSKF standard assortment is shown inmatrix on page 417:
The standard cages used for single row
angular contact ball bearings are
injection moulded cage of glass fibre re-inforced polyamide 6,6 (a), ball centred,designation suffix P,
pressed window-type brass cage (b), ballcentred, designation suffix Y,
machined window-type brass cage (c),ball centred, designation suffix M.
Bearings having a pressed sheet steel cage,
designation suffix J, or machined steel cage,designation suffix F, may also be available.Please check availability before ordering.

Note:Bearings with polyamide 6,6 cages can beoperated at temperatures up to +120 C.The lubricants generally used for rolling
bearings do not have a detrimental effect oncage properties, with the exception of a fewsynthetic oils and greases with a syntheticoil base, and lubricants containing a highproportion of EP additives when used athigh temperatures.
For detailed information regarding thetemperature resistance and the applicabilityof cages, please refer to the section Cagematerials, startingon page 140.

When starting up at low temperatures orwhen the lubricant is highly viscous, evengreater minimum loads may be required.
The weight of the components supported bythe bearing, together with external forces,generally exceeds the requisite minimumload. If this is not the case, the angular con-tact ball bearing must be subjected to anadditional load. Single bearings and bearingpairs arranged in tandem can be axially pre-loaded by adjusting the inner or outer ringsagainst each other, or by using springs.

Minimum loadIn order to provide satisfactory operation,angular contact ball bearings, like all ball and
roller bearings, must always be subjected toa given minimum load, particularly if they areto operate at high speeds or are subjectedto high accelerations or rapid changes in thedirection of load. Under such conditions theinertia forces of the balls and cage, and thefriction in the lubricant, have a detrimentalinfluence on the rolling conditions in thebearing arrangement and may cause dam-aging sliding movements to occur betweenthe balls and raceways.

For bearings mounted in pairs arrangedback-to-back or face-to-face
P0 = Fr + 0,52 Fa
Fr and Fa are the forces acting on thebearing pair.
Determining axial force for bearingsmounted singly or paired in tandemWhen a radial load is applied, the load istransmitted from one raceway to the other
at an angle to the bearing axis and an inter-nal axial force will be induced in single rowangular contact ball bearings. This must beconsidered when calculating the equivalentbearing loads for bearing arrangementsconsisting of two single bearings and/orbearing pairs arranged in tandem.
The necessary equations are given intable , page 414, for the various bearingarrangements and load cases. The equationsare only valid if the bearings are adjusted
against each other to practically zero clear-ance, but without any preload. In the arrange-ments shown, bearing A is subjected to aradial load FrAand bearing B to a radial loadFrB. Both FrAand FrB are always consideredpositive even when they act in the directionopposite to that shown in the figures. Theradial loads act at the pressure centres ofthe bearings (see dimension a in theproduct table).
Variable R
The variable R from table takes intoaccount the contact conditions inside thebearing. The values for R can be obtainedfrom diagram , page 415, as a function ofthe ratio Ka/C. Ka is the external axial loadacting on the shaft or on the housing and C isthe basic dynamic load rating of the bearing,which must accommodate the external axialload. For Ka = 0 use R = 1.

Design of bearingarrangements
When designing bearing arrangements in-corporating single row angular contact ballbearings, remember that these bearingsmust either be used with a second bearingor in sets ( fig ).
When two single row angular contact ballbearings are used, they must be adjustedagainst each other until the requisite preloador clearance is obtained ( section Bearingpreload, starting on page 206).
Where bearings for universal pairing are
used and the bearings are mounted immedi-ately adjacent to each other, there is no needfor adjustment. The requisite preload orclearance is obtained by choosing bearingsfrom an appropriate preload or clearanceclass and by applying suitable fits for thebearings on the shaft and in the housing.
It is important for proper bearing perform-ance and for the operational reliability ofthe arrangement that the bearings are cor-rectly adjusted, or that the correct choice of
preload or clearance has been made. If theclearance of the bearing in operation is toolarge, the load carrying capacity of the bear-

ings will not be fully utilized; on the otherhand, excessive preload will produce morefriction and higher operating temperatures,leading to a reduction in bearing service life.
It should also be remembered that with 72 Band 73 B series single row angular contactball bearings (40 contact angle), correctrolling conditions will only be achieved in thebearing when the load ratio Fa/Fr 1.
Special attention should also be paid toback-to-back and face-to-face arrangementswhere the axial load acts predominantly inone direction. This creates an unfavourablerolling condition for the balls of the unloadedbearing and can lead to noise, discontinuity
in the lubricant film and increased stressingof the cage. Under these conditions, zerooperational clearance is best and should beattained, for example, by using springs. Foradditional information contact the SKFapplication engineering service.
