Single ordinary level (P0, P6, P5 level)

A single ordinary grade angular contact ball bearing is a basic universal angular contact ball bearing with an accuracy of P0 ordinary grade, no pairing, no special material/structure upgrade, and a core all steel foundation configuration with a standard contact angle of 15 °. It is characterized by high cost-effectiveness, universality, and adaptability to single direction axial load+radial load single bearing installation conditions. It is the basic precision support choice for scenarios such as motors, pumps, valves, reducers, and general transmission equipment, and is also the basic bearing for DB/DF/DT pairing.
