N-EUPEX pin coupling


Due to their torsional flexibility N-EUPEX couplings offer the possibility of moving critical torsional vibrations from the operating area of the mechanical equipment in such a way that no negative effects on the drive train are to be expected. N-EUPEX couplings are made of high-quality cast iron. The flexible elements made of synthetic rubber (buna N) are available in different degrees of hardness for many applications. Metal pins and flexible elements are so designed that no wear occurs when properly fitted.

Examples of application

Widely used in the whole field of mechanical engineering, as high-speed coupling on the motor side (e. g. pump, fan or compressor drives) as well as high-torque couplings for the connection of gear unit and driven machine (e. g. mills).
