Introduction for Wheel Hub Bearing :
The main function of the wheel hub bearing is to load and provide precise guidance for the rotation of the car hub. It can bear both axial load and radial load, so it play a important role for the components. The wheel hub bearing is developed on the basis of standard angular contact ball bearings and tapered roller bearings. It integrates two sets of bearings and has good assembly performance, can eliminate clearance adjustment, light weight, compact structure and load capacity. Large, sealed bearings can be pre-loaded with grease, omitting external hub seals and maintenance-free. They have been widely used in cars and trucks.

Application of Wheel Hub Bearing :
With the development of technology, wheel hub bearing have been widely used in cars. The range and use of hub bearings are increasing, and has now reached the third generation: the first generation consists of double row angular contact bearings. The second generation has a flange for fixing the bearing on the outer raceway, which can be simply fixed to the axle by a nut. Make the maintenance of the car easier. The third-generation hub bearing unit is equipped with a wheel hub bearing and an anti-lock brake system ABS. The hub wheel part is designed with an inner flange and an outer flange, the inner flange is bolted to the drive shaft, and the outer flange mounts the entire bearing together.
