Cam roller bearings requiring additional lubrication (stud type roller bearings)

Cam roller bearings (yoke ring type roller bearings) are used for running on all types of tracks, as well as cam drives, conveyor systems, etc. Their bearings are based on the design of needle roller bearings with threaded solid studs instead of inner rings. Their thick-walled outer rings with spherical running surfaces are easy to mount. The narrow gap between the outer ring and the neighbouring parts constitutes a gap type seal. The bearings can be supplemented with lubrication by means of a stud.

  • Particularly high radial load carrying capacity
  • Able to withstand axial loads due to oscillation or tilting
  • Long service life
  • Easy to install
  • Seals for increased reliability with supplementary lubrication
