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.

Introduction

Types GFR, GFRN are roller type freewheels. They are bearing supported, using two

 160.. series bearings, and require oil lubrication. These units may be used in designs

 providing oil lubrication and sealing as on the example overleaf. The bearings must

 not be axially stressed. Typically, types GFR, GFRN are used with the F series covers 

that are designed to transmit torque, and provide oil lubrication and sealing. 

Usually these covers are used in pairs according to combinations shown on the following

 pages. The outer race of the GFR model is plain to receive and center any component 

bored to H7 tolerance. Torque is transmitted by bolts through the cover plate in this case.

 Types GFR, GFRN are identical except that type GFRN has a keyway on the outside 

diameter to transmit the torque. Two paper seals are delivered with each unit to be 

placed between the outer race and cover plates.

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.
