718/500 AGMB-Angular contact ball bearing-FGFA bearings

718/500 AGMB Single row angular contact ball bearing

Angular contact ball bearings can simultaneously accommodate radial and axial loads. They are capable of operating at high rotational speeds. The greater the contact angle, the higher the axial load capacity. High-precision and high-speed bearings typically employ a 15-degree contact angle. Under axial force, the contact angle increases.
