CLAMPEX external clamping sets (shrink disks) allow 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 which provide for friction fit between the shaft and hollow shaft. This friction fit allows for simultaneous transmission of torque and axial force.
Three-part external clamping set / shrink disk
The CLAMPEX® KTR 603 external clamping set (shrink disk) is a shaft-hollow shaft-connection. CLAMPEX KTR 603 external clamping screws (shrink disks) are preferred, among other things, as an alternative to a feather key connection considering their benefits.
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.
