Automobile bearings are one of the key parts of automobiles. They are composed of two sets of tapered roller bearings. Their main functions are to bear weight and provide precise guidance for the rotation of the wheel hub. They can bear both axial loads and radial loads. Bearings are the foundation of automobile transmission parts and part of the drive device on the car. They are known as the "joints of the automobile industry" and are used to support the rotation speed of the tires.
