The Type NF is a Non-bearing-supported built-in one-way clutch from Stieber. It has bearings that support the axial and radial loads. This uses oil as a standard lubricating medium that is needed during installation together with a proper sealing. The clutch is usually installed beside the bearing with the same housing tolerance. It is offered with a nominal outside diameter as a standard ball bearing dimension. The inner race is installed to the shaft, while the outer race has an N6 tolerance in order to fit in an H7 housing. It is offered with additional side notches for a better torque transmission.
