The main role of wheel bearing is to bear the load and provide accurate guidance for the rotation of the hub. It bears both axial load and radial load. It is a very important component. The traditional automobile wheel bearing is composed of two sets of tapered roller bearing or ball bearing. The installation, oiling, sealing and clearance adjustment of the bearing are all carried out on the automobile production line.

This structure makes it difficult to assemble in the automobile production plant, high cost, poor reliability, and the car in the maintenance point maintenance, but also need to clean, oiling and adjustment of bearings. Wheel hub bearing unit is in the standard angular contact ball bearings and tapered roller bearings, on the basis of it will be two sets of bearing as a whole, has the assembly clearance adjustment performance is good, can be omitted, light weight, compact structure, large load capacity, for the sealed bearing prior to loading, ellipsis external wheel grease seal and from maintenance etc, and has been widely used in cars, in a truck also has a tendency to gradually expand the application.
