Angular contact ball bearings are especially suitable for bearing combined loads, that is, loads acting at the same time in radial and axial directions. The axial load bearing capacity increases with the increase of the contact angle α. The contact angle is defined as: the angle between the common normal of the contact point of the rolling element and the raceway or the midpoint of the contact line and the radial plane of the bearing is called the bearing contact angle, and the load is transmitted from one raceway to the other along this connection line. , For single-row bearings, the contact angle can be identified by different code suffixes. 
We can produce many categories and more than 6000 specifications of high-quality bearing products for various purposes and performances, which are sold well in various provinces, municipalities, autonomous regions and more than 50 countries and regions in the world.
