Basic information A cam follower (track follower or track roller) is a specialized type of roller or needle bearing designed to follow cams. It is a rolling element bearings with either an integral stud or an inseparable inner ring for yoke mounting on a pin or shaft.

Cam followers come in a vast array of different configurations, however the most defining characteristic is how the cam follower mounts to its mating part; stud style cam followers use a stud while the yoke style has a hole through the middle.

In cam followers the outer race is loaded at a single point, so the outer race needs a thicker cross-section to reduce deformation. In order to facilitate this the roller diameter must be decreased, which also decreases the dynamic bearing capacity. On stud style followers one of the end plates is integrated into the inner race/stud; the other is pressed onto the stud up to a shoulder on the inner race.

The inner race is induction hardened so that the stud remains soft if modifications need to be made. On yoke style followers the end plates are peened or pressed onto the inner race or liquid metal injected onto the inner race. The inner race is either induction hardened or through hardened. Another difference is that a lubrication hole is provided to relubricate the follower periodically. A hole is provided at both ends of the stud for lubrication. They may also have a black oxide finish to help reduce corrosion.
Cam Roller Technology is ideally suited for material handling, point-to-point, door frame guidance and automation applications. We also offer linear motion solutions for high load transfer and compact, low profile applications.
