Product image CLAMPEX KTR 620 Clamping elements two-parter external clamping set


70 - 7,394,000 Nm / Two-part external clamping set

The CLAMPEX® KTR 620 external clamping set (shrink disk) is a shaft-hollow shaft-connection.

This external clamping set allows for a backlash-free and frictionally engaged connection between cylindrical shafts without keyway and hollow shafts.

The wedge-shaped components of the clamping set that are shifted on top of each other via clamping screws generate radial forces which provide for friction fit between shaft and hollow shaft.

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

The integrated clamping screws of the external clamping set are used for clamping and untightening of the clamping set.

CLAMPEX® KTR 620 external clamping sets (shrink disks) are preferred, among other things, as an alternative to a feather key connection considering their benefits.
