Angular Contact Ball Bearings

Angular Contact Ball Bearings is divided into angular contact ball bearings, double row angular contact ball bearings and four point contact ball bearings. It can bear radial and axial loads at the same time and can bear pure axial load as well with higher limiting speeds. The capability of bearing axial load is determined by the degree of contact angle. The bigger the contact angle is, and the bigger the axial load can be born. The bearings should be used in pair in general, in connection with installation in pairs, there are three kinds of ways, back to back, face to face and in series.
