N-EUPEX Pin Coupling

Please enter your complete MLFB number here

Robust and proven a million times

  • Damping shaft coupling that can be used universally to compensate for shaft misalignment
  • Nominal torque range from TKN = 19 Nm up to 62,000 Nm with 23 sizes
  • Temperature range: from –50 °C to +100 °C

Due to their torsional flexibility, N-EUPEX® couplings can move critical torsional vibrations away from the operating area of 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 designed so that no wear occurs when they are properly fitted.

Did you know?

Original FLENDER® elastomers ensure the optimal operation of your system. The flexible elements of the N-EUPEX coupling are subject to compression. If the flexible elements are irreparably damaged, the hub parts come into contact with metal. This “emergency operation capability” is required, e.g., in the case of fire pump drives.
