Description of DAC Wheel Hub Bearing:
The DAC type auto front wheel bearing is a double row angular contact ball bearing incorporating an integral outer ring and two separable inner rings; which is available either with seals or without seals. Wheel bearings (hub bearing) main role is to load and for the rotation of the hub to provide accurate guidance, both axial load radial load again, is a very important component. Traditional automotive wheel bearing 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 adjustment. 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 maintenance, etc. are omitted from the outside wheel, has been widely used in cars, and in the truck also has a tendency to gradually expand the application.
