At the same time, the bearings must be set up to support both axial and radial diameters. Because the contract curvature is larger than that of the roller, the load is larger, and the torque capacity is larger than that of the roller clutch of the same size, and the wear parts are made of wear-resistant materials due to its special structure. The contact surface between the crucible and the inner and outer rings is also changed accordingly, and the service life is greatly extended.
