Combined needle roller bearings

Product Introduction
JOJI combined needle roller bearings consist of both radial needle roller bearings and thrust bearings. They can accommodate both radial and axial loads. Combined needle roller bearings are particularly suitable for applications where other locating bearing arrangements would require too much space, where axial loads are too heavy, where speeds are too high, or where lubrication is insufficient in bearing arrangements with simple thrust washers. JOJI offers combined needle roller bearings in three basic designs:
  • Needle roller/angular contact ball bearings
  • Needle roller/thrust ball bearings
  • Needle roller/cylindrical roller thrust bearings
The relubrication intervals for the radial and thrust components of the bearing must be calculated separately. The shorter of the two intervals should be used.
