1. Hub bearing is one of the key parts of an automobile. Its main role is to carry weight and provide accurate guidance for the rotation of the hub, which requires that it can withstand not only axial loads but also radial loads.

2. Hub bearing unit is developed on the basis of standard angular contact ball bearing and tapered roller bearing. The two sets of bearings are integrated as a whole, with good assembly performance, which can omit clearance adjustment, light weight, compact structure and large load capacity.
