The wheel hub bearing is one of the key parts of the automobile. Its main function is to carry the weight and provide precise guidance for the rotation of the wheel hub, which requires it to bear not only the axial load but also the radial load.

Chinese name: 轮毂轴承

Type: Bearing

Usage: car

Force: axial load, radial load

Related Background
The traditional automobile wheel bearing is composed of two sets of tapered roller bearings or ball bearings. The installation, oiling, sealing and clearance adjustment of the bearings are all carried out on the automobile production line. This structure makes it difficult to assemble in an automobile factory, with high cost and poor reliability, and the bearings need to be cleaned, oiled and adjusted when the car is maintained at the maintenance point.
The wheel hub bearing unit is developed on the basis of standard angular contact ball bearing and tapered roller bearing. It integrates two sets of bearings, which has good assembly performance, can omit clearance adjustment, light weight, compact structure and load capacity. The advantages of large, sealed bearings can be pre-loaded with grease, omission of external hub seals, and maintenance-free.
