SMITH Cam Followers are anti-friction needleroller bearings developed for use in cam ortrack roller applications. They were specificallydesigned and built to handle intermittentshock and heavy loads. Full compliment (non-caged) needle bearings maximize the radialload carrying capability while the soft inner core of the stud gives these cam followers theability to absorb extreme shock loads withoutfracturing.In addition to standard models, specialbearings are manufactured to customerspecification for unique applications.It is often found that the use of specialbearings reduces machine costs and...

ECCENTRIC CAM FOLLOWERS > Eccentric Sleeves Allow for Radial Location Adjustment of Cam Followers Add Suffix EӔ Cam Followers with a Press Fit EccentricSleeve > provide correct alignment andadjustment without costly preparation ofclose tolerance mounting holes and members. They eliminate problems ofclearances, preloading and wearcompensation and assure load sharing inmultiple cam follower applications. The hex-drive socket allows positive torque forlocking and adjustment. A lock nut willnormally provide adequate clamping to hold bearing and eccentric sleeve in theirproper position. When permanent...

GreaseFitting Fig. 1 shows the re-lubrication path through the thr eaded-end ofthe stud (white area). The head-end is properly closed off using one of the two the plugs provided with each cam follower. Due to diameter constraints of the stud, smaller cam followers cannot be re-lubricated though the threaded-end. Plug Cam Followers and Cam Yoke Rollers arepacked at the factory with a petroleum-base,lithium grease with extreme pressure andcorrosive resistant additives. This lubricant issuitable for most bearing applications within a temperature range of -30F to 250F. Re-lubrication in service can...

L Basic Dynamic Rating ( BDR ), or itsequivalent is an indication of how much dynamic load > Properly selected bearings that havebeen suitably mounted and lubricated will operate for extended periods of timewith minimal wear until the fatigue life ofthe rolling elements is reached. Fatigue life of a bearing is reached when "spalling" or flaking of the contact surfaces (rolling element and raceway) occur from repeated stresses. Once the fatigue life of the rolling element or raceway is reached, wear and ultimate failure of the bearing will occur very rapidly. The purpose is to select theproper...
