up to 1,640,000 Nm / self-centering clamping element with highest performance data

Self-centering clamping element with highest performance data

The CLAMPEX KTR 400 self-centering internal clamping set is a backlash-free clamping element.

These clamping elements enable a backlash-free and frictionally engaged connection between cylindrical shafts without keyway and hub bores (shaft-hub-connection).

The self-centering internal clamping set CLAMPEX KTR 400 has the biggest mounting dimension compared to other internal clamping sets, thus transmitting the biggest forces.

Additional centering between shaft and hub is not necessary.

During assembly the hub is axially displaced towards the shaft.


  • backlash-free shaft-hub-connection
  • simultaneous transmission of torque and axial force
  • additional centering of the hub is not necessary
  • transmitting the highest forces compared to other clamping sets
  • maintenance-free
