Lightweight and highly airtight automotive hub bearing based on rolling technology

Lightweight and highly airtight vehicle based on rolling technologyhubBearings include outer flange bearing outer ring, double row spherical balls, dust cover, internal pressure contact surface, outer flange bearing outer ring, outer ring designed with flange bolt connection holes.

There is a cage on the inside of the outer ring of the bearing with an outer flange, and a double-row spherical ball is arranged on the cage, and a dust cover is arranged on the outside of the double-row spherical ball. The inner ring of the bearing is installed inside the double-row spherical ball, and the inner pressure contact surface The inner ring of the bearing is an internal pressure contact surface, and the internal pressure contact surface is designed with hexagonal fastening bolt holes, and the outer ring of the bearing with an outer flange is designed with a grease fitting.

In order to further improve work efficiency, the main structure of the hub bearing is composed of the outer ring of the bearing with the outer flange, the inner ring of the bearing and the double-row spherical surface sandwiched between the outer ring of the bearing with the outer flange and the inner ring of the bearing. On the outer side of the outer ring of the bearing with an outer flange, the bolt connection holes of the flange are arranged uniformly in a circular shape, and the inner surface of the inner ring of the bearing is designed as an internal pressure contact surface.

Put the cage on the outer side of the inner ring of the bearing, and the double-row spherical balls are evenly fixed on the cage, and the outer side of the double-row spherical balls is equipped with a dust cover, and the inner pressure contact surface of the inner ring of the bearing is designed with a hexagonal sleeve for fastening Bolt holes, grease nipples are designed on the outer side of the outer ring of the bearing with outer flange.
