Development of wheel hub

In the past, single row tapered roller or ball bearings were used in pairs for car wheel hub bearings. With the development of technology, car hub units have been widely used in cars. The application range and amount of wheel hub bearing unit are increasing day by day, and it has developed to the third generation: the first generation is composed of double row angular contact bearings. The second generation has a flange on the outer raceway for fixing the bearing, which can be simply sleeved on the axle and fixed with nuts. So that the maintenance of the automobile becomes easy. The third generation wheel hub bearing unit adopts the bearing unit and anti lock brake system. The hub unit is designed with an inner flange and an outer flange. The inner flange is fixed on the drive shaft with bolts, and the outer flange installs the whole bearing together.
