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.

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.
