Structural characteristics of tapered roller bearings

The type code of the tapered roller bearing is 30000, and the tapered roller bearing is a separable bearing. In general, the outer ring and inner assembly of tapered roller bearings are 100% interchangeable, especially in the size range involved in GB/T307.1-94 "Rolling Bearings - Radial Bearing Tolerances".

The angle of the outer ring and the diameter of the outer raceway have been standardized as the outer dimensions. Changes during design and manufacture are not allowed. So that the outer ring and inner assembly of the tapered roller bearing can be interchanged worldwide.

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