Auto wheel bearings is load-bearing and provide accurate guidance for rotating wheels,both axial load radial load again,is a very important component,Traditional automotive wheel bearings is composed of two tapered roller bearings or ball bearings combination,bearing installation,oiled,and adjust the clearance seals are conducted in automotive production line.This structure makes it difficult in the automotive assembly plant,high costs,poor reliability,maintenance and car maintenance,but also the need for bearing cleaning,oiling and adjutment.

Developed on the basis of the hub bearing unit is the standard angular contact ball bearings and tapered roller bearings on ,it will be two sets of bearings as a whole,with a good assembly performance can be omitted clearance adjustment,light weight,compact structure,load capacity large ,sealed bearings can advance into the grease,hub seals and maintence and more are omitted from the outside wheel,has been widely used in cars,and in the truck also has a tendency to gradully expand the application.
