KR 19 X

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 cylindrical 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.

  • High radial load carrying capacity
  • Accommodate axial loads due to skew or tilting
  • Long service life
  • Easy to mount
  • Sealed for increased reliability, with relubrication feature
