The traditional automotive wheel bearing is a combination of two sets of tapered roller bearings or ball bearings. It is both an axial load and a radial load. It is a very important component. The hub bearing unit is in standard angular contact. Based on the development of ball bearings and tapered roller bearings, it combines two sets of bearings.
Auto bearing feature :
Load-bearing and precise guidance for the rotation of the hub, with good assembly performance, easy to adjust clearance, light weight, compact structure, large load capacity, pre-loading grease for sealed bearings, omitting external hub seals and maintenance-free.
it has been widely used in cars, and there is also a trend of gradually expanding applications in trucks.
