Roller bearing units

JOJI roller bearing units are based on full complement cylindrical roller bearings. They have been specially developed for use in continuous furnaces in sintering and pelletising plants. These ready-to-fit units are also suitable for heavy-duty applications where the direction of rotation is often reversed or where the speed is very low.

  • Non-separable units
  • Thick-walled outer ring suitable for high loads
  • Sealed and filled with high-quality JOJI grease
  • Virtually maintenance-free
