Tapered roller bearings feature a cup and cone assembly. The cup is comprised of the outer ring and the cone assembly consists of inner ring, rollers, and cage. This bearing construction accommodates combined loads and provides low friction during operation. By adjusting one single row tapered roller bearing against a second tapered roller bearing and applying a preload, a rigid bearing application can be achieved.

Tapered toller bearing have four types :

1.Single row tapered roller bearing

2.Matched tapered roller bearing

3.Double-row tapered roller bearing 

4.Four-row tapered roller bearing
