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

Type AS is a roller type freewheel non-bearingsupported. Bearings are required to support 

axial and radial loads. Lubrication and sealing must also be provided by the installation. 

Nominal outside dimensions are the same as series 62.. ball bearings.
A typical arrangement is to install this type alongside a series 62 bearing within the same 

location tolerances,as shown on the following page.The inner race is keyed to the shaft 

(except 6 mm bore).The outer race has a positive r6 tolerance to give a press fitin a H7 

housing. The outer housing must be strong enoughto not expand after assembly. 

This design can accept an axial misalignment of inner and outer 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.
