Wheel bearings support the weight of the vehicle and allow the tires to turn smoothly.

They are important because they have a major impact on safety,ride comfort and fuel efficiency. At the same time, their working

environment is more complicated, and they have higher requirements on the material of the bearing.

Other model

A and A1 are based on the ball and tapered roller bearings respectively, with cylindrical outside diameters. A and A1 both have a two-piece inner ring. Boundary dimensions，including chamfers, are optimized to deliver superior application and cost performance with each specific shaft and housing arrangement.

The advantages of A and A1: are compact, better reliable, and simpler mounting process. It is one of the most used wheel bearings.

A are double-row angular contact ball bearings designed with a large contact angle. This provides the units with the required stiffness to accommodate tilting forces under specified loading conditions.

A1 is double-row tapered roller bearings. The low crosssection and precise contact angle result in a very compact unit, which can accommodate both axial and radial loads.
