Wheel Hub Bearings

The main function of hub bearing is to bear weight and provide accurate guidance for the rotation of the hub. It bears both axial load and radial load, and is a very important component. The traditional automobile wheel bearing is composed of two sets of tapered roller bearings or ball bearings. The installation, oiling, sealing and clearance adjustment of the bearings are carried out on the automobile production line. This structure makes it difficult to assemble in the automobile factory, with high cost and poor reliability. In addition, when the automobile is maintained at the maintenance point, the bearing needs to be cleaned, oiled and adjusted. Hub bearing unit is developed on the basis of standard angular contact ball bearing and tapered roller bearing. It combines two sets of bearings as a whole. It has the advantages of good assembly performance, can omit clearance adjustment, light weight, compact structure, large load capacity, can be filled with grease in advance for sealing bearings, can omit external hub seal and is free from maintenance. It has been widely used in cars, and has the trend of gradually expanding its application in trucks.
