Single-row tapered roller bearings


Single row tapered roller bearings primarily carry combined loads which is main in radial.Tapered roller bearings are widely used in rear axle hubs of automotives, large machine tool spindles, large power reducer, roller wheels of feedways. Matched Type:

Single row tapered roller bearings primarily carry combined loads which is main in radial, and tapered roller bearings with large tapered angle (27°-30°) primarily carry combined loads which is main in axial but nor pure axial loads. These bearings can limit axial displacement of shafts or housings in one direction. The inner and outer rings can be mounted respectively as separable structure, the other rings are interchangeable, and they are easy to mounted and dismounted. The radial and axial clearance can be adjusted during mounting or working, and also can be interference mounted to crease stiffness. The clearance has great influence on bearing performance. 

Tapered roller bearings are widely used in rear axle hubs of automotives, large machine tool spindles, large power reducer, roller wheels of feedways.
