Product Specifications

Tapered roller bearings are uniquely designed to manage both thrust and radial loads on rotating shafts and in housings. We manufacture nearly 26,000 tapered roller bearing combinations – in single, double and four-row tapered roller bearing configurations. Customized geometries and engineered surfaces can be applied to these tapered roller bearings to further enhance performance in demanding applications.
Tapered roller bearings consist of four interdependent components: the cone, or inner ring; the cup, or outer ring; the tapered rollers, or rolling elements; and the cage, or roller retainer. The taper angles allow the bearing to handle a combination of radial and thrust loads. The steeper the cup angle, the greater the ability of the tapered roller bearing to handle thrust loads.
Taper roller bearing application:
Mainly used in axle box,motorcycle rear axle wheel hub, heavy machine tools’ main shafts, big power reduction gears, axletree axle boxes, roller wheels of transportation devices, and the supporting rollers and working rollers of the rolling mills.
