The single-row angular contact ball bearing was designed to support radial, axial or composite loads, however, the axial load must be in one direction. The high thrust capacity is achieved by a higher shoulder on one side of the outer ring. A matching high shoulder is often on the opposite side of the inner ring as well. The direction of the load through the balls forms the contact angle. The thrust capacity increases with the contact angle. This ball bearing has a 40 deg contact angle. This bearing has a stamped steel cage and is not available with seals or shields. These bearings are non-separable. These bearings have normal tolerances and are not suitable for mounting adjacent to each other to achieve a preload. Cost effective. More economical than machined brass cage bearings. Support radial, axial or composite loads in only one direction. Requires grease or oil lubrication for operation. Energy efficient. Reduced friction. Low noise. The raceways of both the inner and outer rings of this bearing type are made with a set contact angle. This bearing type is generally used in adjacent positions.
