High performance sealing ring
Because the hub bearing is very close to the ground and high temperature brake disc and other parts, it needs to adapt to a variety of complex road conditions and harsh driving environment. Therefore, the bearing sealing ring must have good anti-grease performance, but also must have good heat resistance, anti-mud and sewage performance.
Roll rolling technology
The third generation of wheel hub bearing generally adopts rolling technology to self-lock half inner ring. When rolling technology is adopted, axial load causes plastic deformation of the hub spindle end, so that the hub spindle and the half inner ring are connected as a whole. Compared with traditional nut fastening, the third generation hub bearing with rolling technology helps to reduce volume and weight, reduce cost and improve the reliability of hub bearing. At the same time, it eliminates the step of adjusting the position of internal parts when assembling into the car.
