Cam followers and track rollers

A cam follower or track roller is a bearing with a heavy-section outer ring that rolls directly on a cam, guide or track. It mounts either with an integral threaded stud or through a bore onto a shaft. Applications include machine tool cams, linear guides, conveyor systems, automation equipment and any mechanism that needs rolling contact under high radial load.

Each brand has its own designations. At SKF, KR 16 PP, KR 19 PP and KR 22 are stud-type rollers; the number is the roller outside diameter in millimeters, and PP means contact seals on both sides. NTN offers a comparable series, with part numbers like KR16F and KR16FX. INA (KLRU08, KLRZ10) and NSK (FCJ-72, FCR-72) follow series of their own. McGill states the size in inches inside the part number, as in BCCF 1 1/2 S and BCCF 1 1/4 S.

To select one, define the track diameter and width, the mounting style (threaded stud or bore), the outer ring profile and the sealing. A crowned profile tolerates slight misalignment; a cylindrical profile spreads the load evenly on a flat track. In dirty conditions, sealing and lubrication determine service life, and the hardness of the track the roller runs on matters as well.
