The main functions of hub bearing are load-carrying and providing accurate guidance for the rotation of hub. The hub bearing is an extremely important component. It can undertake both axial load and radial load. The traditional bearing that is utilized in the automobile wheels is composed of two sets of taper roller bearings or ball bearings. The installation, oiling, sealing and the adjustment of the clearance are all carried out on the automobiles’ production line. This structure makes it difficult to assemble in automobile factory, cost high and lower the reliability. Also, the bearing needs to be cleaned, oiled and adjusted when the car is maintained at the repair point. Hub bearing unit is developed on the basis of standard angular touching ball bearing and tapered roller bearing. It combines two sets of bearings. It has the following advantages: good assembly performance, omissible clearance adjustment, light weight, compact structure, high load capacity, sealing, capable of preloading grease, omissible outer hub sealing and repairing-free, etc. Now it has been widely applied in saloon cars. Even in heavy-duty trucks, its application is also expanding. Current hub bearing is the third generation one. The first generation is composed of double-row angular touching bearing; the second generation has a flange which is used to pin the bearing . It can easily put the bearing on the bearing axis and pined with the nut. That makes it easier to repair the automobiles. The third-generation hub bearing unit matches the bearing unit with the anti-lock brake system (ABS). There are inner flange and outer flange in the hub unit. The inner flange pined to the driving shaft with the bolt and the outer flange assembles the whole bearing together. The worn or damaged hub bearing or hub unit will result in improper and high-cost lose-efficacy, even insecurity.
