2. Description .
1.The first generation wheel bearing is a double row angular contact bearing components.
2.The second generation wheel bearing have an outer raceway for the bearing retainer flange , the bearing sleeve may simply be fixed with a nut on the axle. Making the car maintenance becomes easy.
3.The third generation wheel hub bearing units are used bearing unit and anti-lock braking system ABS compatible .
4.The fourth generation hub bearing unit is the CVJ and bearing made of a whole, to solve the prior art because the hub and the constant velocity joint integrated structure makes wheel size increases caused by increased weight disadvantage .
3. We also can offer following bearings , please check .
