Structural Features Of Tapered Roller Bearings

The type code for tapered roller bearings is 30000 and tapered roller bearings are separable bearings. In general, especially in GB/T307.1-94 "Rolling bearings radial bearing tolerances" within the size range of tapered roller bearings between the outer ring and the inner components can be used interchangeably.
The angle of the outer ring and the diameter of the outer raceway have been standardized as the dimensions of the outer raceway. Changes are not allowed at the time of design and manufacture. This makes the outer ring and inner components of tapered roller bearings interchangeable worldwide.
Tapered roller bearings are mainly used to accommodate combined radial and axial loads, mainly radial loads. Compared to angular contact ball bearings, the load carrying capacity is large and the limiting speed is low. Tapered roller bearings are capable of holding axial loads in one direction and can limit axial displacement in one direction of the shaft or housing.
