Shrink Discs are external clamping connections for the backlash free fastening of hol- low shafts or hubs to shafts. By tightening clamping screws conical surfaces are pulled together generating radial forces; these forces press the hollow shaft onto the shaft. Torques or axial forces can be transmitted frictionally from the hollow shaft to the shaft. The Shrink Disc itself is not involved in the transmission of torques or axial forces. The radial clamping forces which act through the circumference of the hollow shaft also ensure an optimum centring to the shaft.

Characteristics two-part Shrink Discs
• Easy, quick assembly by tightening clamping screws without a torque wrench
• Modern design with high power density
• Distance-controlled assembly ensures guaranteed transmissible torques
• Enclosed design, therefore impervious to dirt
• True running even at high speeds

Characteristics three-part Shrink Discs
• Tightening of clamping screws with a torque wrench
• Classical design
• Torque-controlled assembly
• Easy disassembly without jacking screws
