Irreversible Locks IR

Product information

INTRODUCTION

Features

Irreversible Locks IR are bidirectional acting roller freewheels with bearing support. They are ready for installation.

The Irreversible Locks IR are used as:

➧ Bidirectional Acting Backstops

Nominal torques up to 100 Nm.

Bores up to 35 mm.

Whereas a normal Freewheel transmits torques from the driving or driven side in only one irection of rotation, with the Irreversible Lock IR it is possible for the driving part to drive the

shaft in both directions of rotation. There is, ho-wever, a locking action against any reverse tor-que coming from the driven part, irrespective of the direction of rotation in which it is exer-ted.
