In angular contact ball bearings, the line connecting the contact points of the balls with the inner and outer rings forms an angle with the radial direction. Contact angles are generally 15°, 25°, and 40°. The axial load that this type of bearing can withstand varies with the contact angle; the larger the contact angle, the greater the axial load the bearing can withstand. Angular contact ball bearings are particularly suitable for applications involving combined radial and axial loads, and can also be used for pure axial loads. When subjected to pure radial loads, angular contact ball bearings generate an internal axial component force, so they must be installed in pairs, such as back-to-back (DB) or face-to-face (DF).
Angular contact ball bearings can be mainly divided into the following categories:
Single-row angular contact ball bearings
Double-row angular contact ball bearings
Four-point angular contact ball bearings
EISENBERG angular contact bearings are mainly used in high-frequency motors, machine tools, fluid transport machinery, printing machinery, automobiles, precision instruments, household appliances, and general machinery.
