hub bearing

 1st wheel bearing is a double row angular contact ball bearing incorporating an integral outer ring and two separable inner rings or a double row tapered roller bearing. In order to ensure the preloading after assembly to meet the requirement ,the  bearing clearance is set in advance. There is no need to use the spacer to adjust the preloading at assembly. And the wheel bearings are self-owned seals so the labour cost is reduced.
