The type code of tapered roller bearings is 30000, and the tapered roller bearings are separable bearings. In general, especially in the size range involved in GB/T307.1-94 "Rolling Bearings - Tolerances for Radial Bearings", the outer ring and the inner assembly of tapered roller bearings are 100% interchangeable.
The angle of the outer ring and the diameter of the outer raceway have been standardized in the same way as the outer dimensions. Changes are not allowed at the time of design manufacturing. As a result, the outer ring and inner assembly of tapered roller bearings are universally interchangeable worldwide.
Tapered roller bearings are mainly used to bear combined radial and axial loads, mainly radial loads. Compared with Angular Contact Ball Bearings, the load carrying capacity is large and the ultimate speed is low. Tapered roller bearings are capable of bearing axial loads in one direction and are able to limit the axial displacement of the shaft or housing in one direction
