The main function of the hub bearing is to bear weight and provide precise guidance for the rotation of the hub. It bears both axial load and radial load, and is a very important component. Especially for the wheel hub bearings of trucks, due to the greater load it bears, the bearing capacity and precision of the wheel hub bearings are even more important.   

A wheel hub assembly (WHA), also referred to as hub assembly，wheel hub unit,wheel hub bearing, is an automotive part used in most cars, passenger vehicles, and light and heavy trucks.
