The first generation: is composed of double-row angular contact bearings. It is widely used.
The second generation: there is a flange on the outer raceway for fixing the bearing, which can simply set the bearing to the wheel axle and fix it with a nut. It makes the maintenance of the car easy.
The third generation: wheel bearing unit is used with bearing unit and anti-lock brake system ABS.
The fourth generation: wheel bearing unit is to make the universal joint and bearing into a whole, solving the shortcomings of the existing technology due to the increase in weight of the wheel hub caused by the increase in size of the wheel hub and the universal joint as a whole.
Generally, the car should check the wheel hub bearings after 50,000-80,000 kilometers.
Wheel bearing is one of the key parts of the car, its main role is to carry the weight and provide precise guidance for the rotation of the wheel hub.
Wheel bearings can withstand both axial and radial loads.
