ROTEX® clamping ring hubs

0 - 4,500 Nm / torsionally flexible jaw coupling

Jaw coupling with clamping ring hubs for fricitionally engaged shaft-hub-connections

ROTEX clamping ring hubs are torsionally flexible elastomer couplings with an integrated clamping system for frictionally engaged shaft-hub-connections.

Thanks to the integrated clamping system the ROTEX clamping ring hubs are able to transmit high friction torques. The internal clamping screws allow for easy assembly of the coupling.

Due to the rotation symmetry this type is additionally characterized by particularly smooth running


  • torsionally flexible jaw couplings with integrated clamping system

  • friction connection for cylindrical shafts

  • application up to a circumferential speed of 40 m/s 

  • particularly smooth running

  • high friction torques
