Angular Contact Ball Bearing 7300 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.
