C . ASNU(NFS) Series One Way Clutches Roller Type Details
Product Features	One Way Clutches Roller Type mainly used as Overrunning and Indexing clutches; Overrunning clutches:The freewheel disengages automatically when the driven member rotates faster than the driving member. Indexing clutch:The freewheel allows the conversion of reciprocating motion into a discontinuous rotational movement.
Series Introduction	ASNU(NFS) is a roller type freewheel nonbearing supported. Bearings are required to support axial and radial loads. Lubrication and sealing must also be provided by the installation. Nominal outer diameter is the same as a series 63...Ball bearing. A typical arrangement is to install this type alongside a bearing within the same location tolerances, as shown on the following page. The inner race is keyed to the shaft. The outer race has positive n6 tolerance, to give a press fit in a H7 housing. Additional side notches in the outer race provide for positive torque transmission. If the housing is to K6 tolerance, use of the notches is not necessary, but the housing must be strong enough to not expand after assembly. This design can accept an axial misalignment of inner and uter race of ± S/2.

Applications	Reducers , Flender Gearbox ,SEW Gearbox; Overrunning clutch:for multiple-machine drives or to separate the inertia of masses of a driven machine from the driving machine after it has been switched off. Indexing clutch:which turns a shaft step by step, thus achieving indexed material feed or a variable speed. Backstop clutch:to prevent a machine shaft turning backwards. In this case the overrunning clutch acts as a brake.
