The original two sets of discrete angular contact ball bearings or tapered roller bearings are integrated into a whole set of outer ring, inner ring back-to-back combination.The best working clearance is preset before delivery to customer. It is not necessary to adjust when using and installing, and designs multi-lip labyrinth seal structure, professional lubrication, easy to install, compact structure and reliable performance.

The hub bearing outer ring is made into an integral structure with the hub flange.In addition to all the advantages of the first generation bearing, the integration of its outer ring and hub flange has a good rigidity, high reliability, light weight and can effectively shorten the production cycle.

Integrate hub bearing with hub & mounting flange (brake side and knuckle side) and sensor into an assembly component.The third generation hub bearing unit with wheel speed sensor has become a development trend.Compared with the second generation hub bearing unit, it has better rigidity, stronger bearing capacity and higher reliability.And built-in wheel speed sensor, achieved the development of mechatronics.
