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.

Application : Bidirectional Acting Backstop

Housing Freewheels FH with hydrodynamic roller lift-off are typically used in cases where an assembly can be driven from two or more motors or turbines at the same or similar high speed. They allow a continuous plant oper­ation in the event that one of the energy sources or a drive line fails as well as energy saving in the case of partial load operation. The Housing Freewheels FH are completely enclosed freewheels for stationary arrangement with input and output shaft.

Application : Overrunning Clutch,at high speeds, which are the same or similiar in freewheeling operation and in driving operation.
