Product Key Facts
Product Description
Torsionally highly flexible coupling with a segmented elastic element.

High speed shaft - Low speed shaft of compressor driven by electric motor or diesel engines with non-SAE flywheel.


  • The segmented construction assures easy handling at installation and easy maintenance
  • High flexibility to minimise torsional vibration.
  • High axial, angular and radial misalignment capacity with minimum reaction forces.

Tailor-made Solutions

  • Different torsional stiffnesses provide the satisfactory tuning of the torsional vibration behaviour of the drive system.
  • Custom built-in length of the coupling available on request.
  • ATEX Certification available on request.


  • Segmented design, displaced arrangement in case of multi-row design and ventilation holes guarantee the good ventilation of the elements.
