Introduction

Type RSCI is a centrifugal lift off sprag type freewheel with the inner race rotating. 

Only the inner race is designed for freewheeling. It is a non self- supported type.Bearings

 must be provided to ensure concentricity of the inner and outer races support axial and 

radial loads, as shown overleaf. Concentricity and run-out limits must be observed.

 The RSCI type accepts all types of lubricant currently used in power transmission 

equipment. It is possible to mount these freewheels directly in gear-boxes without 

separate lubrication. An oil mist is generally sufficient. Grease lubrication may be 

acceptable if the unit works mostly in overrunning condition, as on E-motors.When used

 as a backstop, it must be checked that the overrunning speed will not go below the 

minimum speed given in the characteristics table.

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.
