High performance seal
Because the hub bearing is very close to the ground and high temperature brake discs and other parts, it needs to adapt to various complicated road conditions and harsh driving conditions. Therefore, the bearing seal must have good grease leakage resistance, and must also have good heat, mud and sewage resistance.
The third-generation wheel bearing generally adopts the self-locking semi-inner ring of the rocking technology. When the rocking technology is used, the axial load causes the spindle end of the wheel to be plastically deformed, so that the hub main shaft and the semi-inner ring are integrally connected. Compared to conventional nut tightening, third-generation hub bearings with rocking technology help reduce size and weight while reducing cost and improving the reliability of the hub bearings. At the same time, the step of adjusting the position of the internal components is eliminated when assembling to the car.
