GMN freewheel cluches are used in many devices. The most important of them are: printing machines, conveyors, hoisting devices, agricultural machines (seeders), electric power switches, textile machines, automatic transmissions in vehicles.

All GMN backstops have the following features:

• The coupling curve depends on the specific outline of the individual sizes of the rolling and locking elements (cams).
• A very small front surface, which allows the maximum number of rolling-blocking elements to be placed in a specific surface to be built-in, gives the possibility of transmitting the maximum torque.
• The 400 series uses a log spiral shaped clamping curve that provides the best possible load distribution for all rolling and locking elements, which is especially important for small diameters.

In all designs of rolling-blocking elements used in GMN clutches, the average values ​​of division accuracy were exceeded, which increases their reliability.
