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

Type NFR is a bearing supported roller type freewheelwithout any sealing. Lubrication and 

sealing must be provided by the installation. Standard lubrication is oil.Size 8 to 20 units use steel on steel bearing support from the inner race. Above size 25, two 160.. series ball bearings are used,giving a higher overrunning speed capacity. A typical arrangement is shown overleaf.The inner race is keyed to the shaft. The outer race has a positive n6 tolerance to give a press fit in a housing to H7.Additional side notches provide for positive torque transmission.The housing must be strong enough to not expand after assembly.

ApplicationsReducers , 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.


 D . NFR type One Way Clutches Roller Type Installation & Cautions

For all freewheel inner races connected to shaft by a key, our stand-ard bore tolerance is H7, with keyway

 to JS10. If no other indication we recommend a shaft tolerance of h6 or j6. For maximum indexing accuracy,

 adjusted keys should be machined to give no clearance.

Shaft and bore tolerances are speci-fied on the pages for each type where press fitting is appropriate.As

 with standard bearings, suitable tooling must be used for press fitting such that no axial load is 

transmitted through the inner part of the freewheel during assembly.
