Tapered Roller Bearings

Tapered Roller Bearings

Tapered Roller Bearing is composed of an inner ring, outer ring, and tapered rolling elements,bearings 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 the tapered roller bearings on the rolling tracks is variable, which in each case offsets the application axial and radial loading ratio; at a larger angle, a greater ability to withstand axial loads.

CNB has a wide range of tapered roller bearings consisting of detactable elements that make them easily adjustable in applications.

The most popular applications for this bearing type are:
1.Wheel hubs for light, industrial, and agricultural vehicles
2.Transmissions (gearboxes and differentials)
3.Machine tool spindles
4.PTOs(Power Take-Off)
