GFR40 One Way Clutches Roller Type (40x125x86mm) One Way Bearings Freewheel Clutch

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.

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.

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.
