Structural characteristics of tapered roller bearings

- Sep 15, 2019-

The type code of tapered roller bearings is 30,000, and tapered roller bearings are separate bearings. In general, especially in the dimensions covered by GB / T307.1-94 "Tolerances for rolling bearings, radial bearings", the outer ring and inner components of the 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 outer dimensions. No changes are allowed during design and manufacture. As a result, the outer ring and inner components of tapered roller bearings can be universally interchanged worldwide.

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