28 - 1,460,000 Nm / Three-part external clamping set

Three-part external clamping set/shrink disk

The CLAMPEX KTR 603 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 sets that are shifted on top of each other via clamping screws generate radial forces ensuring friction fit between shaft and hollow shaft. This friction fit allows for simultaneous transmission of torque and axial force.

Compared to other types of clamping sets, disassembly of the CLAMPEX KTR 603 external clamping set is much easier, since KTR 603 releases automatically when unscrewing the clamping screws.

CLAMPEX KTR 603 external clamping sets (shrink disks) are preferred, among other things, as an alternative to a feather key connection considering their benefits.
