Family specifications and selection conditions
| Product description | Cam followers (stud-type track rollers) are designed to run on all types of tracks and to be used in cam drives, conveyor systems, etc. They are based on a double row full complement cylindrical roller bearing with a threaded solid stud instead of an inner ring. The design includes an eccentric collar pressed onto the stud, and a thick-walled outer ring with a crowned running surface. The bearings are supplied sealed and ready-to-mount, and can be relubricated via the stud. |
|---|---|
| Manufacturer features | High radial load carrying capacity • Accommodate relatively heavy axial loads due to skew or tilting • Long service life • Easy to mount • Sealed for increased reliability, with relubrication feature |
