Tapered roller bearings can withstand large radial and axial loads. Since tapered roller bearings can only transmit axial loads in one direction, another symmetrically mounted tapered roller bearing is required to transmit axial loads in the opposite direction.

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

The outer ring angle and outer ring diameter have been standardized to outer dimensions. Changes are not allowed during design and manufacture. The outer ring and inner parts of tapered roller bearings can be interchanged worldwide.
