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. The direction of the load through the balls forms the contact angle. The thrust capacity increases with the contact angle. The BMU bearings are commonly referred to as thrust bearings. These bearings have a 40 deg contact angle to accept heavy axial loads. The bearings have Universally Flush Ground rings to facilitate mounting in multiple bearing sets. The inner and outer rings have identical widths. These bearings can be mounted as DB, DF and DT pairs or can be combined into triplex and quadraplex sets. When two bearings are mounted together, a clearance or preload may be obtained without the use of shims or spacers. This bearing has a machined brass cage and is not available with seals or shields. These bearings are most commonly used in vertical pump and motor applications. Higher precision. Increased speed and load carrying capacity. Support radial, axial or composite loads in only one direction. Capable of moment loads if used in pairs. Machined brass cage. Energy efficient. 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.
