Description

Tapered roller bearing is composed of an inner ring, outer ring, and tapered rolling elements. They can withstand combined loads (axial and radial). In addition, this design allows rolling movement without the rollers slipping off the tracks of the outer and inner rings. 


 

The contact angle of CNB tapered roller bearings on the rolling tracks is variable, which in each case offsets the application axial

The popular applications for this bearing type are:

  • Wheel hubs for light, industrial, and agricultural vehicles
  • Transmissions ( differentials and gearboxes)
  • Machine tool spindles
  • PTOs
