Compact alternative to CLAMPEX KTR 200

The self-centering internal clamping set CLAMPEX KTR 203 is a backlash-free shaft-hub-connection. CLAMPEX KTR 203 is the compact alternative to the CLAMPEX KTR 200 internal clamping set.

The clamping element CLAMPEX KTR 203 allows for a backlash-free and frictionally engaged connection between cylindrical shafts without keyway and hub bores The wedge-shaped components of the clamping sets that are shifted on top of each other via clamping screws generate radial forces ensuring friction fit on the contact surfaces of shaft and hub bore.

This friction fit allows for simultaneous transmission of torque and axial force.

The integrated clamping screws of the clamping set are used for clamping and releasing the clamping sets, depending on the type of clamping set. Additional centering between shaft and hub is not necessary. During the 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

  • shorter mounting lengths compared to KTR 200

  • maintenance-free
