The Thin Section Angular Contact Ball Bearings(A Type) are mainly applied to support both radial load and single direction axial load. It needs to be installed in pairs if applied to support double direction axial load through the way of Face to Face installation (DF), Back to Back installation (DB) and Tandem installation(DT).
The difference between the Thin Section Radial Contact Ball Bearings (C Type) and the Thin Section Angular Contact Ball Bearings (A Type) is that the Thin Section Angular Contact Ball Bearings have big enough radial clearance that causes a contact angle to bear the axial load. The degree of the standard contact angle is *0.

The bore diameters of our Angular Contact Bearing range from 1.**0 inch to *0.**0 inch. Series range from 0.***5 X 0.***5 inch to 1.**0 X 1.**0 inch in cross section. In these series, the material of rings could be GCr*5 and stainless. By using the same series of thin-section bearings throughout a products line, the designer could standardize on common components.
