QJ 1096 N2MA-Angular contact ball bearing-FGFA bearings

QJ 1096 N2MA Four-point contact ball bearing with locating slots

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.
