Angular Contact Bearings are constructional bearings that use "balls" as the rolling elements. The bearings have the inner and outer raceways being displaced relative to each other in the direction of the axis of the bearing. This means that the bearings can accommodate a combination of loads, axial and radial. The common types of angular contact bearings include the single row, double row, four-point and super-precision. Angular contact bearings are considered ideal for high-speed applications. Good examples include electric motors
, gearboxes, pumps
, and clutch
. They are also highly reliable when used in materials handling, steel mills, and machine tools. It is prudent to note that although the angular contact bearings can handle load only in one direction, they can be manufactured with varying angles (0-45 degrees) to transfer the load upon the bearings. Some of the key benefits of using the angular contact bearings include: 1) They are capable of withstanding heavy axial forces in one direction as well as radial loads because of the angle. The higher the angle of contact, the higher the axial thrust that the bearing can withstand. 2) Because of the construction ability, they are able to withstand a significant level of angular misalignment of the supported shaft.
