Long Life Cam Followers; Material Han dling Rollers andSheaves; and Airframe Track Rollers and Needle Bear ings.RBC also produces a wide range of custom de signed camfollowers and track rollers. Designers and users with un- usu al ap pli ca tion re quire ments should contact RBC to dis cuss custom designed cam followers.

Savings at Every Turn!RBC Bearings produces the most in no va tive line of cam

followers in the industry. The entire line is made frombearing quality steel for optimum performance. From thepatented, long-life, RBC Roller® Cam Fol low er to the inventory reducing HexLube® line, RBC achieves costsavings and pro vides features that are unmatched by competitors. If you have a special ap pli ca tion that is notserved by the exhaustive list of products shown in this catalog, RBC has the en gi neer ing resources to create custom designed cam fol low ers that will meet your needs.

RBC Roller®

The patented RBC Roller® is the leading cost-saver inthe industry. This long-life cam follower lasts up to 400%longer than standard cam followers, with no main te nance!You can calculate your savings at our interactive websitewww.rbcbearings.com.

The RBC Roller® is di men sion al ly interchangeable withneedle roller cam followers. The RBC Roller® is a goodselection for production ma chin ery ap pli ca tions wheredown time is critical and must be avoid ed, or where camfollowers are not readily accessible for relubrication orreplacement. They are available in stud type (page 8) andyoke type (page 10) configurations.

Two paths of end-guided, cylindrical rollers pro videsubstantial increases in fatigue life and limiting speed.They can tolerate higher thrust loads than needle roller cam followers. Stan dard con tact ing lip seals offer en- hanced pro tec tion against con tami nants and positive grease re ten tion. A large internal grease cavity assuresmain te nance-free service. Hex sockets are a standard fea ture. Crowned outer rings are available as an option.

HexLube®

RBC’s new Universal HexLube® line of cam fol low erscan reduce your inventory by about 50%! This innovativeline can elim i nate the need for you to stock screwdriver slotor unsealed cam followers. Find out how much your in ven to ry can be reduced at www.rbcbearings.com.

The new HexLube® feature allows hex head cam followers to be relubricated through the hex head – a greatconvenience in tight spaces or when stud access is im pos si -ble. This feature is now available in sizes from 3/4” to 7”

with either a standard stud or heavy stud. Eccentric andcrowned versions are also avail able. Standard hex headcam followers are available in smaller sizes starting at 1/2”.

Needle Roller Cam FollowersNeedle Roller Cam Followers have a heavy outer ring

cross section and a full complement of needle rollers. Theyoffer high dynamic and static load car ry ing capability, andanti-friction per form ance, in a compact design. They areused as track rollers, cam followers, and in a wide range oflinear motion systems.

Standard Stud cam followers (page 14) offer the mount -ing convenience of a threaded stud and are designed to ac com mo date moderate loads. They are available with andwithout seals. Standard stud cam followers are also availablewith crowned outer rings (page 16) for ap pli ca tions wheremisalignment is a prob lem.

Heavy Stud cam followers (page 20) are designed toprovide additional stud strength for applications with high loading or shock loads. Heavy stud cam fol low ers are available with and without seals, and with crownedouter rings (page 22).

Yoke Type cam followers (page 24) are intended primarily for applications where loading conditions exceed the capabilities of stud type cam followers, or where clevis mounting is desired. Clevis mounting provides support on both sides of the cam follower andpermits use of a high strength pin. Yoke type cam fol low- ers are available with and without seals, and with crownedouter rings.

CamCentric® adjustable cam followers (page 18) areused where accurate positioning is required. They are par ticu larly useful for reducing clearance or backlash inopposed arrangements, and for assuring load sharing inmultiple cam follower installations. Seals and hex socketare stan dard features of CamCentric® adjustable cam fol low ers. Crowned outer rings are also available.

Crowned Outer Rings are used to minimize outer ringthrust ing in applications where the axis of the cam fol -low er is not parallel to the surface of the track or is skewedrelative to the direction of travel. Crowned outer rings area good selection for use with curved or circular tracks. Inwell aligned ap pli ca tions, crowned outer rings can causeaccelerated track wear.

Caged Roller FollowersCaged roller followers (page 26) provide large inter nal

grease storage capacity for applications where relubrication isinfrequent. Cage guided rollers and a very heavy outer ringcross section permit operation at high loads and high speeds.Caged roller followers are avail able with and with out seals.The un sealed design provides the ad di tion al advantages ofvery low friction to prevent skidding in lightly loaded

applications and provides for flow-through lu bri ca tion.Caged roller followers normally mount directly on a

hard ened and ground pin. RBC offers a line of PrecisionGround Inner Rings (page 28) to simplify application ofcaged roller followers. More in for ma tion on shaft andmounting considerations is pro vided in part 5.4 of the technical section (page 45).

Material Handling Rollers and SheavesRBC offers a wide range of rollers and sheaves spe cifi -

cally designed for material handling ap pli ca tions—lifting,conveying, and power trans mis sion. All RBC rollers andsheaves use heavy duty roller bearing con struc tion whichprovides maximum dynamic and shock capacity for longer service life than ball bearing de signs.

Lift Truck, Crane and Conveyor Rollers (page 30, 31)commonly referred to as mast guide rollers or car riagerollers, are used in lift truck masts and carriages, trav el lingcranes, and conveyor lines, where max i mum capacity in ananti-friction roller is required. Sealed, lubricated-for-lifeversions are available.

Chain Sheave and Sprocket Idlers (page 32, 33) forBL-leaf and ANSI “rollerless” roller hoisting chain are es sen tial components of hoisting systems such as lift

trucks and car lifts. They are also used as track rollers andas tensioners in power trans mis sion chain drives.

Airframe Track Rollers and Needle Bear ings

Airframe track rollers and needle bearings are de signedfor high load carrying capability, light weight, and slowrotation or oscillatory motion. The exposed surfaces areplated to provide corrosion re sis tance. They are used in aircraft flap, slat and control ap pli ca tions, and in numerousnon-aircraft applications.

Series NBC needle bearings (page 34) offer high capacity, thin cross section and unitized construction. They are commonly used in pivots and linkages.

Series NBE and NBK needle bearings (page 36, 37)provide a spherical aligning outer ring to allow for mis -align ment. Applications and performance char ac ter is ticsare otherwise similar to series NBC.

Series NBF and NBL track rollers (page 38, 39) are de signed with heavy outer ring cross section for track roller ap pli ca tions. They offer a corrosion resistant alternative to con ven tional yoke type cam followers.

he RBC Roller® was developed for customersneed ing a high degree of assurance of long cam follower life. It can be used to great advantage inconveyors, automotive transfer lines or processindustries—food, beverage, plastics, glass and others.The RBC Roller® is also attractive for defense ap pli ca -tions, where system reliability and maintainabilityare primary design goals. The inter nal design andcon struc tion differ from typical needle bearing, ballbearing, and tapered roller bear ing cam followers.The RBC Roller® design is unique and is covered byPatent 5531137.

Two paths of cylindrical rollers create stable outerring support. The comparatively large diameter ofthe rollers provides substantially increased dynamiccapacity and fatigue life. On a size by size basis, theRBC Roller® offers at least twice, and up to nine timesthe fatigue life of conventional needle roller bearingcam followers.

A center thrust ring in the RBC Roller® impartsend guidance to the two paths of rollers. Conventionalneedle roller bearing cam followers rely on outer ringcurvature and controlled circumferential clearance forroller guidance. The needle rollers often skew duringnormal operation, generating unnecessary heat whichcan lead to premature failure. When com pared toneedle roller bearing cam followers, end-guidedcylindrical rollers allow the RBC Roller® to run atlower operating temperatures and higher speeds.

Thrust loading in the RBC Roller® is ac com mo -dat ed through contact between outer ring flanges androller ends, and contact between roller ends and thecenter thrust ring. This provides the RBC Roller® withsu pe ri or thrust capability. As a result, the RBC Roller®

is tolerant of tracking misalignment and axial loadsthat would overwhelm other designs.

RBC ROLLERStud and Yoke Type

Contacting lip seals are a standard feature of theRBC Roller®. These seals ride on smooth ground surfaces on the inner ring or stud. This sealing sys -tem provides positive exclusion of solid and liquid contaminants, and excellent lubricant re ten tion.When compared to clearance seals typical of mostcam follower designs, the RBC Roller® con tact ing lipseals ensure superior protection in demanding environments.

The RBC Roller® is pre-lubricated at the factorywith a high quality mineral oil, NLGI grade 2 grease.The space between the two paths of rollers which iscreated by the center thrust ring provides a largegrease storage cavity. This larger than normal abilityto store lubricant, in combination with excellentgrease retention of the contacting lip seals, makes theRBC Roller® virtually maintenance-free. Under mostoperating conditions relubrication is not nec es sary.

The design of the RBC Roller® provides the ad di -tional benefit of positive, unitized construction.Conventional cam followers rely on swaging or staking, particularly in yoke type configurations, tomaintain integrity of the assembly. If adequate axialclamping is not provided, these designs can driftapart and cause catastrophic failure. During as sem -bly of the RBC Roller®, the center thrust ring per ma -nently engages a circumferential groove in the stud orinner ring. This design feature ensures integrity of the assembly during handling and operation, andsimplifies mounting design.

The RBC Roller® is available in stud and yoke typeconfigurations. Standard sizes range from 1 1/4inches outside diameter to 10 inches outside di ame -ter. The RBC Roller® is dimensionally interchange-able with standard needle roller bearing cam followerdesigns.

Uni ver sal line of cam fol low -ers, designed with a unique lu bri cat ing fea ture. The RBCHexLube® Uni ver sal Cam Followerallows for relubrication through thehex ag o nal head of the cam follower, making relubrication in tight spots possible. In addition, theuniversal design of the RBC HexLube® Cam Followercan eliminate the need to stock both screwdriver slotand unsealed cam fol low ers. RBC expects that mostcustomers can reduce their in ven to ry on stud typecam fol low ers by 50% using this new universal line.The complete line is available in sizes with an outsidediameter from 3/4 inch to 7 inches. The RBC HexLube® Universal Cam Followerdesign pro vides the easiest and fastest way to relubricate cam followers in hard to reach places or inap pli ca tions where stud access is limited. A cam follower that is properly maintained and lubricatedwill last longer than a cam follower that is neglected

due to the difficultiesposed by relubrication.

Companies looking tosharply reduce their inventory

levels will recognize the value ofRBC's uni ver sal design of the new

HexLube® Cam Follower. By stock -ing the RBC HexLube® line, companies will no longerneed to carry inventories of either screw driv er slot orunsealed cam followers. The entire line of RBC HexLube® Universal CamFollowers is dimensionally interchangeable withother needle bearing cam followers. The RBCHexLube® Uni ver sal Cam Follower is available inboth ec cen tric and crowned versions. Both standardstuds and heavy studs are available as well. RBC HexLube® Universal Cam Followers are de signed for ap pli ca tions such as automation andproduction equipment, bottling and canning,print ing machinery, material han dling, constructionequip ment, transfer lines, food processing, and packaging equipment.

BC developed the Universal Cam Fol low erproduct line to replace standard cam fol low ers, anddelivered two obvious ben e fits. First, it is possible torelubricate the hex head cam follower through thehead. The hex head feature is the pre ferred mountingmethod for stud-type cam followers, and now it canbe relubricated in tight spots or when stud access is re strict ed. Sec ond, the HexLube® can eliminate theneed to stock both screwdriver slot and unsealed cam followers. Your inventory can be reduced by about 50%!

RBC looked at the cam follower market and found358 line items and five manufacturers (1790 line items!)The challenge was to reduce the number of part num -bers needed to satisfy the market without sac ri fic ingfeatures and benefits. The answer was the “Uni ver salCam Fol low er Product Line.” The HexLube® cam fol -low er allows lubrication through the head of the camfollower, eliminating the need to stock the screw driv erslot series. Also eliminated from the line were all un -sealed cam followers. Re duc ing your inventory by thislarge amount results in real savings. The end result isa product line with just 186 line items!

MatchingInner Rings

(See page 28)Max.Min.NominalMin.

All dimensions are in inches.

Normal operating loads should not exceed the bearing dynamic capacity.

Roller followers used without inner rings require a shaft with minimum hardness of Rc 58 and surface finish of 16 rms or better.

Standard configuration of roller follower series SRF-- SS is with seal lips facing outward. To specify roller followers with seal lips facing inward, replace suffix -SS with suffix -RR. (example: SRF 30 RR).

TECHNICAL DATA

the outer ring around the point of contact. The effectsare outer ring deformation with reversed bendingstress es in dynamic applications, a reduced load zone, and a higher maximum roller load (see Fig. 1.).

To keep deformation to a minimum, the outer ring ofa cam follower must have a considerably heavier cross section than a standard bearing. This re quire -ment conflicts with the desire for maximum dynamicbearing capacity which needs as large a roller di ame -ter as possible. RBC cam followers and yoke rollersprovide an optimum compromise between outer ringstrength and theoretical bearing capacity.

2. Capacity and Load Limits

Evaluation of the expected service life and limit loadsof cam followers is more complex than with housedbear ings. In addition to the static and dy namic capacityof the rolling elements, outer ring de for ma tion, track ca pac i ty, and cam follower stud bending stress must becon sid ered. In yoke rollers, the pin shear stress must becon sid ered.

RBC lists the static bearing capacity for referencepurposes only. Typically, the maximum allowable loadis a function of the maximum permissible bend ingstress of the stud or the outer ring. For best results, theoperating loads should not exceed the lower of trackcapacity or 50% of the dynamic ca pac i ty.

2.1 Capacity of Rolling Element Bearing

Equations for static and dynamic capacities of roll erbearings are given in ANSI/ABMA Standard 11. Themore recent revisions leave it up to the manu fac turer toin tro duce factors which account for internal design features and operating conditions. For cam followersand yoke rollers RBC has chosen to apply a con ser va tiverating sys tem, so a direct comparison with ca pac ity figures of competitive products may not be pos sible.

1. Difference from Standard Bearings

The outer rings of regular ball and roller bearingsare typically mounted in rigid housings providingsup port around the entire circumference. Individualroller forc es are transmitted through the outer ringdirectly into the housing with no major deformations.

By contrast, cam followers and yoke rollers are supported at a single point on their circumference.Individual roller forces produce bending moments on

Track capacity is that load which a track subject to auniform contact stress can withstand without ex ces siveplastic deformation. It is directly related to track hard -ness. The published track capacity is based on a hard nessof HRc 40. For other track hard ness values the trackcapacity must be modified with factors from Table 1.

2.3. Bending and Shear Stresses

2.3.1 Cam Follower Stud Bending Stress

If the load over the width of the outer ring isevenly distributed, it may be replaced by a singleconcentrated force F [lbf] acting at the center of thecam follower (see Fig.2). Assuming that the cam follower stud has been tightly mounted in a housingbore flush with the end plate, this concentrated forcegenerates a bending moment Mb.

where B = outer ring width [in]1/32 = cam follower overhang [in]

The bending moment generates a bending stressin the cam follower stud of approximate magnitude

where SD=Stud Di ame ter [in]

Standard cam follower studs are heat treated to ahardness of HRc 58 min in the raceway area only.

Fig. 2

Table 1. Track Capacity Adjustment Factors.

Alternatively, contact stress can be easily cal cu -lated and compared directly to the strength of ma te -rial. The equation for the Hertz contact stress be -tween a cylindrical cam follower outer ring and a flatsteel track is given by “Roark, Formulas for Stressand Strain” as:

F = radial load [lbf] leff = length of outer ring contact [in] D = outer ring diameter [in]

It can be shown that for infinite life the ultimatetensile strength of track and roller must be at leastequal to the maximum contact stress

Referring to Table 1, 149,800 psi is between 146,000 psi(HRc32) and 165,000 (HRc 36). Interpolation yields aminimum track hardness of HRc 33.

Page 42: RBC Rolle r , HexLube , CamCentric Cam Followers · RBC Bearings Incorporated (RBC Bearings, RBC) has had a long tradi-tion of innovation, commitment, and quality since the company

42

The hardness in other areas of the stud is typically in arange of HRc 20 -22 with an ultimate strength of material of 110,000 -120,000 psi. RBC bases the maxi -mum allowable load of stud type cam followers on atheo reti cal stud bending stress of 100,000 psi. Stan -dard stud cam fol low ers and heavy stud cam fol low -ers differ in stud di ame ter, which permits higher op er at ing loads and more resistance to impact load- ing for the heavy stud version. High stud strengthcam followers are available by special order.

In most applications the stud will deflect awayfrom the load, which causes the point of attack to shift toward the support, shortening the moment arm and reducing the effective bending moment (seeFig. 3). Tests show that this de flec tion yields a safetyfactor of at least 2 over RBC’s maximum al low ableload. How ever, this effect may not be sufficient toavoid damage in severely misaligned applicationswhere the load is applied at the very extreme out -board edge of the cam follower outer ring.

Where misalignment is a problem, RBC rec om -mends crowned cam followers.

Example 2Cam follower S 64 L supports a load of 6,000 lbf.The stud diameter is .875", the outer ring width 1.25".Determine the theoretical bending stress at the studhousing interface.

Solution:

2.3.2 Yoke Roller Pin Shear Stress

Yoke rollers are mounted with a pin in a yoke.Under load the pin is subject to shear and bendingstresses. RBC recommends that the yoke arms arelocated as close to the yoke roller as possible, so thatbending stress can be ignored. In case of widelyspaced pin supports, the resulting pin deflection maycause yoke roller dam age.

The pin shear stress can be calculated with

where d=pin diameter

The permissible stress depends on the pin materialselection.

Example 3Determine the shear stress of the .375 in. diameter pinfor yoke roller Y 40 L, loaded radially with 3,200 lbf.

Solution:

2.4 Outer Ring Stress and Deformation

The exact calculation of these values is beyond thescope of this introduction. The following methodmay be used for a (high) first estimate of the outerring tensile stress at the inside diameter opposite thecontact point of a single row cam or roller follower.The assumption is that the entire load is supported byonly 2 rollers straddling the point of contact:

where F = cam follower load [lbf]

In case of constant load, the equivalent radial loadequals the constant load. To compute the equivalentload for all other cases, use:

where q = 10/3 for roller bearingsFt = individual radial load [lbf]

4. Speed Limit and Maximum Acceleration

4.1 Speed Limit

The limiting speed of rolling element bearings ispri mar ily a function of size and internal design. Thespeed limits given in this catalog should not beexceeded on a con tinu ous basis to prevent prematurefailure due to excessive temperature. Contact RBC forsolutions to high speed applications.

4.2 Maximum Acceleration (Deceleration)

A sufficiently large tangential friction force Ft , acting between outside diameter and track is neededto change the rotational speed of cam follower andyoke roller outer rings.

(10)

where � = coefficient of friction (outer ring to track)

The force Ft produces a moment Mt, which mustaccelerate the masses of outer ring and rollers aroundthe bearing axis, plus the rollers in the load zonearound their own axes.

Example 4 Estimate the outer ring tensile stress of yoke roller Y 56 L subject to a load of 6,000 lbf. The yoke rollerhas 25 rollers, the outer ring outside diameter = 1.750in., the outer ring raceway diameter =1.125 in., theideal ized outer ring width = .690 in.

the life which 90% of a large group of apparently iden -ti cal rolling element bearings will complete or exceed.For a single bear ing, L10 also refers to the life associat-

ed with 90% reliability.

The relationship between fatigue or rating life, ca pac ityand load is:

(6)

where L10 rev = Rating life [106 rev] C = Dynamic capacity [lbf] Pe = Equivalent radial load

To obtain the rating life in hours, use

(7)

L10 hrs = Rating life [hours] where ne = equivalent speed [rpm]

In case of constant speed, the equivalent speed equalsthe constant bearing speed. In all other cases theequiva lent speed is the weighted average of all in di -vid ual speed components.

RBC offers a convenient socket (W suffix) for hexwrenches to pro vide a more substantial grip, es pe -cially for ‘blind hole’ applications.

5.2 Eccentric Cam Followers

Eccentric cam followers are used when there is aneed to make height adjustments between the cam follower and the track. By simply turning the entirecam follower inside the housing it is possible to adjust the distance between the cam follower and thetrack by twice the eccentricity. However, due to theme chan i cal advantage that the eccentricity provides, it is in ad vis able that the cam follower be adjusted over this entire range.

A very large force can be exerted on the track for asmall applied adjusting torque as the eccentricity ofthe cam follower approaches ±90 degrees from a starting position parallel to the track, in the housing.Ad just ments should be limited to ±45 degrees and the re sult ing preload should not exceed 10% of thecam follower’s capacity.

The following equation can be used to find anappropriate adjusting torque.

T = 0.1 * C * e * cos 45° [in * lbf] where T = appropriate adjusting torque [lbf]

C = cam followers dynamic capacity [lbf]

e = eccentricity of cam follower [in]

Example 5CamCentric cam follower S48LWX has a dynamiccapacity of 4,600 lb, and an eccentricity of 0.03 in.Determine the appropriate adjusting torque.

Solution: T = 4,600 lbf * 0.03 in * 0.070711 = 9.76 in * lbf

The moment Mt can be calculated using:

Accelerating the mass of the outer ring normally

re quires the largest part of moment Mt. Assuming

a co ef fi cient of friction of � = 0.10 and a typical cam follower design, the following equation may be used foran estimate of the permissible angular ac cel era tion α:

(12)

Excessive acceleration causes sliding of the outerring on the track. The effects range from minor uniform wear on cam follower and track to flat spotson the cam follower with subsequent failure.

5. Mounting

5.1 Cam Followers

For greatest rigidity and strength, the end plateshould be drawn up snugly against a boss or otherflat surface of the housing. The tables on pages 8throughout 23 list the maximum recommendedclamp ing torque for lu bri cated threads, which is thenormal condition. Use up to twice the listed torquefor completely dry threads.

The housing bore should be drilled and reamed tothe recommended tolerance. If a greater tolerance isneeded, it should be added to the plus side to preventcam follower damage during assembly. If the cam follower stud fits tightly into the housing bore, use anarbor press and apply pressure against the centralportion of the flange. Never press against the rim ofthe flange or the outer ring.

Although wide blade screwdrivers may be used tohold slotted head cam followers during assembly,round ed tools conforming to the slot are preferable toavoid plastic deformation in the slot area.

cam followers require relubrication depending on operating speed, duty cycle, operatingen vi ron ment, desired service life, etc.

For relubrication in service, mineral oil, or any goodroller bearing grease on mineral oil basis may be used.Inquire about compatibility of greases with differentbase oil and thickener.

Except for the very small sizes (see tables), cam fol low ers with screwdriver slots can be relubricatedfrom both ends of the stud and through the housing.Table 2 lists suitable drive fit Alemite fittings. Plugs are furnished by RBC to close off unused passages.

Table 2. Alemite fittings.Cam followers of the HexLube® series are supplied

5.3 Yoke Rollers

RBC yoke rollers correspond in many respects to thesame size cam follower, except they are mounted on apin for use in yoke type applications for greater shock re sis tance.

Yoke rollers should be clamped axially or mountedwithin closely fitting side rails to prevent dis place mentof the end plates. For applications with heavy loads, it is recommended to heat treat the pin and use a press fitfor the inner ring. A soft pin and light press or push fitare sufficient for lightly loaded applications. When press fitting a yoke roller, pres sure should be appliedcentrally and uniformly against the end plate, neveragainst the outer ring.

The pin should have a suitable lead-in chamfer orradius to prevent scoring and to hold the mountingforce to a minimum.

5.4 Caged Roller Followers

Caged roller followers can operate directly on a hard -ened and ground shaft (HRc 58 min, 16 rms min surfacefinish) or can be used with matching inner rings. Op er at -ing without an inner ring yields the largest possible shaftdiameter with greatest strength and rigidity. Axial guid ance must be pro vided by the application. It is rec om mended to use hardened steel or bronze thrustwashers with radial lu bri cat ing grooves as needed.

6.1 Track Lubrication

In most applications it is difficult to eliminate all camfollower misalignment. Misalignment causes the outerring to thrust, which in needle bearing cam followers,pro duc es wear of the seal followed by wear of the outerring face and the stud flange or the end plate. In RBCRollers ® the wear is generallly limited to the center thrustring. Misalignment where the axis of the cam follower isnot perpendicular to the direction of rolling, typicallyproduces the most severe thrust and also causes wear onthe cam follower outside diameter, and the track. Toreduce these symptoms as much as possible, the trackmust be lubricated. Lubrication also reduces wear stem -ming from excessive acceleration. Oil and grease areacceptable lubricants.

If the track cannot be lubricated, contact RBC Engineer-ing for a review of the operating parameters to ensure thatthey do not exceed the limits of the bearing selected.

6.2 Bearing Lubrication

Cam followers and yoke rollers are pre-lubricatedwith an NLGI grade 2, lithium soap, mineral oil basedgrease with EP additives. RBC Roller® type cam fol low -ers and yoke rollers are nor mally lubricated for life andhave no provisions for relubrication. Needle roller type

with a grease fitting at the bottom of the hex hole. Yokerollers and sealed roller fol low ers must be relubricatedthrough the shaft.

7. Misalignment

Initial misalignment should not exceed .001 in./in.Any misalignment generates thrust forces be tween outerring and flange or end plate. Excessive thrust ing can leadto increased operating temperature and destruction of theseal in stan dard cam followers and yoke rollers. Wheremisalignment and outer ring thrusting cannot be avoided,RBC rec om mends crowned outer rings or the RBC Roller®

design which is more capable of withstanding thrust loads. Contact RBC engineers about thrust and load limits.

8. Operating Temperature

The temperature limits of all standard cam followersand yoke rollers in this catalog, except airframe bearings,are determined by the temperature limits of the seals andthe lubricant. With lower temperatures, grease graduallybecomes stiffer, increasing the rolling resistance of thecam follower. Any application with the cam followeroperating continuously below 0° F (-18° C), consult withRBC Engineering for a specific low temperature grease.The maximum continuous operating temperature is+250° F (120° C), and for short periods, the maximumtemperature may rise to +300° F (150° C). For continuousoperation above +250° F (120° C), consult with RBCEngineering to determine the need for special high tem-perature grease and seal material.

RBC can provide special so lu tions for applicationsoutside the normal operating temperature range.

TYPICAL APPLICATIONS

Material Handling EquipmentCarriage rollers and side rollers of lift trucks are typicalapplications where roller followers have performed ex ceed -ingly well. The heavy walled outer ring eliminates the needfor a separate tire and bearing assembly.

Drum CamA pair of heavy stud cam followers are shown mounted inlink ag es activated by a drum cam or grooved rotating shaft.A lu bri ca tion hole through the stud accepts a drive fittingfor pe ri odic relubrication.

Rewind StandsRewind stands for packaging material or printed coils makeuse of cam followers. A simple two or three point supportconsists simply of several cam followers acting on the journalor body of the roll. The upper bracket is optional and a veryquick changeover results in either case.

Table SupportsYoke rollers may be effectively mounted to support tables,tracks or other machine members requiring linear motion.The illustration depicts horizontal location between yokerollers, but this may be achieved by cam followers or Cam-

Centric® followers as well.

Turntable MountingCam followers can be mounted in a circular housing tosupport a ring or thrust plate. Precise leveling adjustmentfor the turntable can be obtained using the adjustableCamCentric® cam follower.

Internal Combustion EnginesRBC's yoke roller followers have found wide ac cep tance asvalve tappet and fuel injection rollers. The outer ringflanges support the cage against high inertia loads assuringpositive, individual roller control by the cage.

TYPICAL APPLICATIONSCluster MountingCluster mounting of four cam followers around a squarecolumn demonstrates the unique versatility of these bearings.Threads are concentric with the shank within very close limits. This feature is important on “blind hole” mountingswhere run-out would result in binding.

Manual Lift TruckSchematic arrangement of cam followers is shown on theupright of a warehouse hand truck. CamCentric® bear ingsare frequently used to provide adjustment so that all bearingscontact the track without critical hole positioning.

Textile MachineryThe sealed yoke rollers work extremely well as picking rollsof looms due to the fact that the minimum friction assuresconstant turning to eliminate wear.
