GMN insert elements are available in many different diameters. The FE 400 Z, FE 400 Z2 and FE 8000 Z series are equipped with a tension spring. The FE 400 M series has a meander spring. GMN insert elements are designed for installation on hardened and ground connecting parts. They are suitable for either oil or grease lubrication. All GMN insert elements can be used as indexing clutches, backstops or as overrunning clutches.
The FE 400 Z series contains freewheel clutch insert elements with tension springs.

The freewheel clutch insert element requires axial constraints on both sides.
Hardening and grinding of the mating parts are necessary. Chamfered shafts and hubs ease installation.
Freewheel clutch insert elements are not self-centering. External bearing support to define the gap between mating parts (Shaft and housing) is necessary.
