details:
 

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 usually used in pairs.
The material of the cage is brass, synthetic resin, etc., depending on the bearing type and the conditions of use.
Angular contact ball bearings are available in 7000C (∝=15°), 7000AC (∝=25°) and 7000B (∝=40°) types. The bearing of this kind of bearing is on the outer ring. Generally, the inner and outer rings cannot be separated, and can bear the combined load of radial and axial directions and the axial load in one direction. The ability to withstand axial loads is determined by the contact angle, and the greater the contact angle, the higher the ability to withstand axial loads. This type of bearing limits the axial displacement of the shaft or housing in one direction.
Contact ball bearings have a high limit speed and can withstand radial and axial loads. They can also withstand pure axial loads. The axial load capacity is determined by the contact angle and increases with the contact angle.
Single row angular contact ball bearings can only withstand axial loads in one direction. When subjected to radial loads, they will cause additional axial forces and must be applied to the corresponding reverse loads. Therefore, these bearings are generally used in pairs. Double row angular contact ball bearings can withstand large radial and axial bidirectional combined loads and moment loads, mainly radial loads, which limit the axial displacement of the shaft or casing in both directions with a contact angle of 30 degrees.
Paired mounted angular contact ball bearings can withstand radial and axial bidirectional combined loads with radial loads and can withstand pure radial loads. The series configuration can only withstand axial loads in one direction, while the other two configurations can withstand axial loads in either direction. This type of bearing is generally selected by the manufacturer and assembled into a pair of users. After installation, there is preloading and interference, and the ferrule and the steel ball are in an axial preload state, thus improving the whole set of bearings as a single support stiffness and rotation. Precision.
The main purpose of angular contact ball bearings:
Single row angular contact ball bearings: machine tool spindle, high frequency motor, gas turbine, centrifugal separator, small car front wheel, differential pinion shaft
Double row angular contact ball bearings: oil pumps, Roots blowers, air compressors, various types of transmissions, fuel injection pumps, printing machinery
