Irreversible Locks IR, For Bidirectional Acting Backstop

Irreversible Locks IR are bidirectional acting ­roller freewheels with bearing support. They are ready for installation. 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 ­direction 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, however, a locking action against any reverse torque ­coming from the driven part, irrespective of the direction of rotation in which it is exerted.
