Spekuma is the general agent for GMN, which is a leading manufacturer of freewheel Cluches.

A freewheel is a machine element whose function only allows rotation in one direction while supporting or transmitting torque in the opposite direction. A backstop is a condition where a fixed output side prevents the driven side from rotating in the locking direction. Power transmission occurs from the driving side to the driven side. Torque can be applied via either the outer ring or the inner ring, depending on the requirements. The freewheel maintains its width even when rubber seals (RS) are used. Additionally, it offers high indexing accuracy and high transmissible torque.

The application areas for freewheels are almost limitless, and the product can be used in a variety of applications, including bicycles, printing machines, generators, and helicopters.
