Angular Contact Ball Bearings

The angular contact ball bearing is classified into the single row angular contact ball bearing, double row angular contact ball bearing and four point contact ball bearing. It can bear radial and axial loads at the same time and can bear pure axial load as well with higher limit rotation speed. The capability of bearing axial load is determined by the degree of contact angle. The bigger the contact angle is, the heavier the axial load can be borne. The contact angles are classified to 15, 25 and 40degrees. When the bearing bears radial load, additional axial force will occur. Therefore, a relevant axial load in the opposite direction must be applied. The bearings should be used in pair in general. In connection with mountage in pairs, there are three kinds of mountages, namely, back to back, face to face and in series.
