Description

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.
