ENGINEERING GENERAL INFORMATION Cam Followers Stud & Yoke Type

ECCENTRIC CAM FOLLOWERS
Eccentric Sleeves Allow for Radial Location Adjustment of Cam Followers Add Suffix “E” Cam Followers with a Press Fit EccentricSleeve

The eccentric sleeveallows for easy radialpositioning for stud-type cam followers.

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 locking ofeccentric sleeve is required, drill through the housing, eccentric sleeve, and bearing studand secure with a dowel or set-screw.
EccentricSleeve In-line Adjustment Allows Greater Location Tolerance for Mounting Holes Control of Clearance andAdjustment for Wear CROWNED CAM FOLLOWERS
Crowned Outer Races Reduce Edge Loading when Bearing/Track are Misaligned Add Suffix “C” Unwanted edge loading of needlebearings causes skewing and end thrusting of the needles which contribute to premature bearing failure. In situationswhere it is impractical or too costly to provide for perfect alignment, crownedbearing O.D.s provide compensation formisalignment between the cam followerand the surface of a slanted track or cam.The radius also eliminates skidding of the outer race when bearing is on contact with a flat, circular cam.

Crowned outer races are recommended when the track is not exactly aligned and square with the cam follower. Crowned outer races reduce undesirable thrust loads on the rollers when track-bearing mis- alignment happens to occur. This increases life andreliability of the bearing.

Available in stud type and yoke type cam followers. SEALED CAM FOLLOWERS
Seals Provide Protection Against Contamination & Loss of Lubricant Add Suffix “X”

Seals provide an effectivemeans of protection from outside contamination and ensure lubricant retention.

Seal Available in stud type and yoketype cam followers.Sealed cam followers are furnished withmolded-acetyl full-contact seals contained within the outer race undercuts at both endsof the bearing. This is a low-friction materialwhich keeps drag to a minimum yet is stableand unaffected by corrosive agents orlubricants. A small vent hole in the seals allows for purging during relubrication withoutcausing seal displacement. The outer race onsealed cam followers is provided with amachined groove in the bore, which acts asa grease reservoir to extend time periods between relubrication. All sealed bearingsare dimensionally interchangeable with theunsealed configuration of the same series.
