Angular Contact Ball Bearings 7900 Series

Angular Contact Ball Bearing 7900 Series have a contact angle; they are designed to sustain significant combined axial and radial load simultaneously. RunFine axial load carrying capacity increases with respect to the bearing's contact angle. The contact angle (∝) is defined as the angle between the line contacting the raceway and ball.

Matched Angular Contact Ball Bearings such as Back-to-back (DB), Face-to-face (DF) arrangements are also available for usage in applications where radial and axial loads in both directions can be sustained. Regarding the tandem arrangement (DT), please contact RunFine Technical Support.

RunFine Precision Angular Contact Ball Bearing 7900 are designed with brass solid or glass-fiber reinforced nylon cage options. The bearings are available in open and sealed versions as well. For special applications where the bearing rigidity factor is of top-most consideration, rigidity requirements can be customized accordingly for reinforced bearing structure.
