Angular contact Ball Bearing introduction:
Angular contact ball bearings can withstand both radial and axial loads. Can work at higher speeds. The greater the contact angle, the higher the axial load carrying capacity. High-precision and high-speed bearings usually take 15 degrees of contact angle. With an axial force, the contact angle increases. Single-row angular contact ball bearings can only withstand axial loads in one direction and, when subjected to radial loads, will cause additional axial forces. And can only limit the axial displacement of the shaft or shell in one direction. In the case of paired double mounting, the outer rings of a pair of bearings are opposed, that is, the wide end faces the wide end face, and the narrow end faces the narrow end face. This avoids additional axial forces and limits the shaft or housing in the axial clearance in both directions.
Angular contact ball bearings can have relative displacement on the horizontal axis due to the raceways of the inner and outer rings, so they can simultaneously bear radial load and axial load - joint load (single row angular contact ball bearings can only withstand unidirectional axial load, Therefore, it is generally used in pairs. The material of the cage is brass, synthetic resin, etc., and it is divided according to the type of bearing and conditions of use.
Angular contact ball bearings are available in several types: 7000C (∝=15°), 7000AC (∝=25°) and 7000B (∝=40°). The lock of the bearing is on the outer ring. Generally, the inner and outer rings cannot be separated, and they can bear radial and axial combined loads and axial loads in one direction. The ability to withstand axial loads is determined by the contact angle. With large contact angles, the ability to withstand axial loads is high. This kind of bearing can limit the axial displacement of the shaft or shell in one direction.
