About 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.
Application field
Widespread use in all mechanical engineering, both on the motor side as a high-speed coupling, e.g. pump, fan or compressor applications as well as at high torques for connecting gear units and driven equipment, e.g. mills.
Advantages of the product
- Torsionally rigid and damping pin coupling to be used universally for compensating shaft misalignments
- Maximum operational reliability, since fail-safe
- Suitable for plug-in assembly and simplified replacement of elements in the type consisting of three parts
- Dynamic adaptation by selection of elastomer hardness

Note
1) The formula symbols are defined here.
2) The permissible axial offset is applicable for offsets that slowly occur, e.g. as a result of thermal expansion of the coupled shaft.
3) Permissible shaft offset at rated speed nN = 1500 min-1.
4) Torsional stiffness at 0.5 * TKN, excitation amplitude of 0.1 * TKN with 10 Hz, ambient temperature 20°C.
5) The orderer is responsible for verifying the design strength of the shaft-hub connection.
