The cam follower and track roller is a thick-walled bearing, with an outer ring that rolls directly on a cam, guide, or track, and which can have an integral threaded stud or a bore for mounting on a shaft. It is used in machine tool cams, linear guides, conveyor systems, automation equipment, and mechanisms that require rolling contact with high radial load.
Designations depend on the brand. In SKF, KR 16 PP, KR 19 PP and KR 22 correspond to stud-type rollers, and the number is the outer diameter of the roller in millimeters; PP indicates contact seals on both sides. NTN uses a similar series with codes such as KR16F and KR16FX. INA, with KLRU08 and KLRZ10, and NSK, with FCJ-72 and FCR-72, have their own series. McGill, on the other hand, expresses the dimension in inches within the code, as in BCCF 1 1/2 S and BCCF 1 1/4 S.
To choose, define the track diameter and width, the mounting method (threaded stud or bore), the outer ring profile, and the sealing. Crowned profiles tolerate small misalignments, and cylindrical ones distribute the load evenly on a flat track. In dirty environments, sealing and lubrication define the service life, and the hardness of the track against which it rolls also matters.
The brands we work with in this subcategory are McGill, NTN, INA, NSK and SKF. To quote, send us the complete code or the dimensions: track outer diameter, width, stud or bore diameter and length, and thread type. The equivalence with another brand also works.
