KOYO auto tapered roller bearing included cup and cone there two parts.Cup is outer ring,Cone comprise rollers, cage,inner ring.And the inner ring with the rollers and cage can be fitted separately from the outer ring.

1)Tapered roller bearings are separable and have the following components: outer ring, inner ring, and roller assembly (containing the rollers and a cage). 

2)The non-separable 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 cone relative to the cup. 

3)Tapered roller bearing included cup and cone there two parts.Cup is outer ring, Cone comprise rollers,cage,inner ring.And the inner ring with the rollers and cage can be fitted separately from the outer ring.

4)The tapered roller bearings are generally used to support combined load mainly consisting of radial load. The carrying capacity of axial load depends on the contact angle of raceway of outer rings. The bigger the contact angle is, the stronger the capacity will be .
