The type code of tapered roller bearing is 30000, and the tapered roller bearing is separated bearing. In general, especially in the dimension range of GB / t307.1-94 rolling bearing centripetal bearing tolerance, the outer ring and inner assembly of tapered roller bearing are 100% interchangeable.

The angle of the outer ring and the diameter of the outer raceway have been standardized as the same as the overall dimension. It is not allowed to change during design and manufacturing. So that the outer ring and inner assembly of tapered roller bearing can be interchanged in the world.

Tapered roller bearings are mainly used to bear the combined radial and axial loads which are mainly radial loads. Compared with the angular contact ball bearing, the bearing capacity is large and the limit speed is low. Tapered roller bearing can bear axial load in one direction and limit axial displacement of shaft or shell in one direction.
