ROLB type roller type one-way overrunning clutchDetailed product description：

The ROLB type is a roller type one-way clutch without bearing support. The ROLB model requires bearing installation to prevent axial and radial stress. Lubricating grease has been added at the factory.
The external dimensions are the same as those of the 63 series standard bearings. The typical installation method is that all ROLB models are placed next to the bearings, in the same position, with the same tolerance requirements. The inner ring and shaft are installed using keyway method. The end face keys on both sides of the outer ring are used to fix the outer ring and the machine wall to transmit torque.
