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 a contact angle of 15 degrees. 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 to axial play in both directions.
The contact ball bearing has a high limit rotation speed and can bear both radial and axial loads, as well as pure axial load. Its 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 can cause additional axial forces and must be applied to corresponding reverse loads. Therefore, these types of bearings are generally used in pairs. Double-row angular contact ball bearings can withstand large radial and axial bidirectional combined loads and moment loads with radial loads. It can limit the axial displacement of the shaft or the housing in both directions. The contact angle is 30 degrees.
Paired mounting angular contact ball bearings can withstand both radial and axial bidirectional combined loads with radial loads, and can also withstand pure radial loads. The series configuration can only withstand axial loads in one direction, while the other two configurations can accommodate axial loads in either direction. This type of bearing is generally selected by the manufacturer as a pair of submitted users. After installation, there is a pre-press interference, the ferrule and the steel ball are in an axial preload state, thereby increasing the entire set of bearings as a single support stiffness and rotation. Accuracy.
The main purpose of angular contact ball bearings:
Single row angular contact ball bearings: machine tool spindles, high frequency motors, gas turbines, centrifugal separators, small car front wheels, differential pinion shafts
Double row angular contact ball bearings: Oil pumps, Roots blowers, air compressors, various types of transmissions, fuel injection pumps, printing machinery
