Overrunning Clutches & Backstops

NF

Stieber Clutch NF Type

Type NF is a roller type freewheel non-bearing supported. Bearings are required to support axial and radial loads. Lubrication and sealing must also be provided by the installation.

Standard lubrication is oil. Nominal outside diameter is a standard ball bearing dimension. A typical arrangement is to install this type alongside a bearing with the same housing tolerances, as shown on the following page. The inner race is keyed to the shaft. The outer race has a positive n6 tolerance to give a press fit in a H7* housing. Additional side notches provide for positive torque transmission.

If the housing tolerance is to K6*, use of the notches is not necessary, but the housing must be strong enough to not expand after assembly.
