About the Hub BEARING

2018-06-27 The main function of the hub bearing is to bear weight and provide accurate guidance for the rotation of the hub. It is an important component because it supports both axial and radial loads. The traditional bearings for automobile wheels are composed of two sets of tapered roller bearings or ball bearings. The installation, oiling, sealing and clearance adjustment of bearings are all carried out on the automobile production line. This structure makes it difficult to assemble, high cost, and poor reliability in an automobile factory. Moreover, when a car is maintained at a maintenance point, the bearing needs to be cleaned, oiled, and adjusted. The hub bearing unit is developed on the basis of standard angular contact ball bearings and tapered roller bearings. It combines two sets of bearings. It has good assembly performance, can eliminate clearance adjustment, light weight, compact structure, and load capacity. Large, sealed bearings can be pre-loaded with grease, omission of external hub seals and maintenance-free advantages, have been widely used in cars, there are also gradually expanding the application of the trend in trucks.
