In the past, most of the wheel hub bearings of cars used single row tapered roller or ball bearings in pairs. With the development of technology, car wheel hub units have been widely used in cars. The range and amount of use of wheel hub bearing units are increasing day by day, and have developed to the third generation: the first generation consists of double row angular contact bearings. The second generation has a flange on the outer raceway for fixing the bearing, and the bearing can be simply sleeved on the axle and fixed with a nut. Makes car maintenance easier. The third-generation wheel hub bearing unit is a combination of the bearing unit and the anti-lock brake system. The hub unit is designed with an inner flange and an outer flange, the inner flange is bolted to the drive shaft, and the outer flange mounts the entire bearing together.
