The application of bearings on semitrailer axles
The wheel hub bearing is one of the key components of the automobile. Its main function is to carry weight and provide precise guidance for the rotation of the wheel hub, which requires it to not only bear axial load, but also radial load.

Since the semi-trailer axle itself cannot provide power and does not have a steering function. Therefore, the wheel hub bearing has become the most important component of the semi-trailer axle and is often known as the "heart" of the axle.
