KR22 SKF Cam Follower Bearing
Cam follower (stud-type track roller) with relubrication feature.
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 needle roller bearing with a threaded solid stud instead of an inner ring. They have a thick-walled outer ring with a crowned running surface and are supplied ready-to-mount. A narrow gap between the outer ring and the adjacent components forms a gap-type seal. The bearings can be relubricated via the stud.
- PP = Contact seal on both sides
- A = Improved crowned profile of the outer ring running surface
- .2RS = NBR contact seal on both sides
- X = Cylindrical (flat) profile of the outer ring running surface
