The motion transmission devices are necessary for a proper connection of electromechanical axes and cylinders with motors or gearboxes.

Mod. COE couplings are composed of two hubs with a high concentricity clamp and an elastomeric element.
Mod. COS couplings are composed of one hub with a high concentricity clamp, a hub with expansion shaft and an elastomeric element.
The torque transmission is performed without angular play or vibrations. Both couplings are without angular play thanks to the pretensioning of the elastomer between the two semi-couplings.
Mod. COT locking-sets are composed by an internal and an external conical ring connected with eachother by means of several screws. Through the tightening of the screws, an axial force is generated that enables the torque transmission from the shaft to the hub.
