How Do Angular contact ball bearings work effciently?

Angular contact ball bearings can support both radial and axial loads. Can work at higher speeds. The larger the contact angle, the higher the axial load capacity. High-precision and high-speed bearings usually have a contact angle of 15 degrees. Under the action of axial force, the contact angle will increase. Single-row angular contact ball bearings can only bear axial loads in one direction, and they will cause additional axial forces when bearing radial loads. And can only limit the axial displacement of the shaft or housing in one direction. If it is installed in pairs, the outer rings of a pair of bearings are opposite, that is, the wide end face is opposite to the wide end face, and the narrow end face is opposite to the narrow end face. This prevents additional axial forces and limits the shaft or housing to axial clearance in both directions.

Angular contact ball bearings, because of the relative displacement of the inner and outer ring raceways on the horizontal axis, can support both radial and axial loads-combined loads (single-row angular contact ball bearings can only support unidirectional axial loads, Therefore, they are usually installed in pairs). The material of the cage includes brass, synthetic resin, etc., which are differentiated according to the bearing type and use conditions.

Angular contact ball bearings are 7000C (∝ = 15 °), 7000AC ( = 25 °) and 7000B (∝ = 40 °). The lock of this kind of bearing is on the outer ring. Generally, the inner and outer rings cannot be separated, and can bear the combined radial and axial loads and the axial load in one direction. The ability to withstand axial loads is determined by the contact angle. The larger the contact angle, the higher the ability to withstand axial loads. This type of bearing can limit the axial displacement of the shaft or housing in one direction.
