Angular Contact Ball Bearings

With a proper contact angle, angular contact ball bearings can bear significant axial loads in one direction together with radial loads. When a radial load is applied, an axial force component will be produced. Therefore, two opposed bearings or a combination of more than two bearings must be used.
In general, angular contact ball bearings have two different designs: separable and nonseparable. Contact angle of separable bearing is 15°, contact angle of non-separable bearing are 15°, 25°or 40° respectivity. Separable angular contact ball bearings can be divided into removable inner ring and removable outer ring according to the internal structures.
