Tapered Roller Bearings

Click to enlarge image
The inner and outer ring raceways and rollers of the tapered roller bearing are made with a taper so that the surface planes of the raceways and roller axis meet at a point. The rollers are guided by a flange on the inner ring.

Tapered roller bearings are separable and have the following components: outer ring, inner ring and roller assembly. The nonseparable inner ring and roller assembly is called the "cone", and the outer ring is called the "cup". Internal clearance is established during mounting by the axial position of the come relative to the cup.
