CLAMPEX® internal clamping sets

CLAMPEX® internal clamping sets are shaft-hub-connections allowing 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 that provide for 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 are used for clamping and untightening of the clamping set depending on the type of clamping set.

CLAMPEX® internal clamping sets are used, among other things, as an alternative to a feather key connection considering their benefits.
