What is angular contact ball bearing

Angular contact ball bearings are mainly subjected to large one-way axial loads. The larger the contact angle, the greater the load bearing capacity. 

The cage material is steel plate, brass or engineering plastic. The forming method is stamping or turning, depending on the bearing form or the conditions of use. Other combinations of angular contact ball bearings, double row angular contact ball bearings and four-point contact ball bearings. 

Angular contact ball bearings can withstand both radial and axial loads. Can work at higher speeds. The larger the contact angle, the higher the axial load carrying capacity. High precision and high speed bearings typically take a 15 degree contact angle. Under the axial force, the contact angle will increase. 

Single row angular contact ball bearings can only withstand axial loads in one direction and will cause additional axial forces when subjected to radial loads. And can only limit the axial displacement of the shaft or casing in one direction. 

If it is installed in pairs, the outer rings of a pair of bearings are opposite, that is, the wide end faces the wide end faces, and the narrow end faces the narrow end faces. This avoids causing additional axial forces and limits the shaft or housing to axial play in both directions. 

Angular contact ball bearings can withstand radial and axial loads due to the relative displacement of the inner and outer races on the horizontal axis. Combined load (single row angular contact ball bearings can only withstand uniaxial axial loads, Therefore, it is generally used in pairs. The material of the cage is brass, synthetic resin, etc., depending on the bearing type and the conditions of use.


7000C type (∝=15°), 7000AC type (∝=25°) and 7000B (∝=40°) The bearing of this kind of bearing is on the outer ring. Generally, the inner and outer rings cannot be separated and can withstand radial and axial directions. The combined load and the axial load in one direction. The ability to withstand axial loads is determined by the contact angle, and the contact angle is large, and the ability to withstand axial loads [1] is high. This type of bearing limits the axial displacement of the shaft or housing in one direction.
