Shrink discs, 2-piece (torque-controlled)

The two-piece shrink disc (torque-controlled) is an external clamping element consisting of a pressure ring and a sleeve. Tightening the clamping screw to the specified torque draws the pressure ring axially onto the sleeve. The use of conical surfaces reduces the inner diameter of the sleeve, thus exerting a radial clamping force on the hollow shaft. The clamping force applied by the shrink disc connection creates a friction-fit connection at the contact surface between the shaft and hub. Compared to the three-piece shrink disc, the two-piece shrink disc has a smaller cone angle and a self-locking function. Due to the small cone angle, the sleeve has additional release threads that allow the pressure ring and sleeve to be forced apart during disassembly. The two-piece shrink discs (torque-controlled) do not have a defined insertion path. This allows them to compensate for larger tolerances during assembly. The clamping screws of the two-part shrink disc (torque-controlled) are tightened evenly in a sequential manner until the specified tightening torque is reached. Once this assembly state is achieved, it is ensured that the torques specified in the catalog can be transmitted.
Two-part shrink discs (torque-controlled) are available in various designs. Depending on the available installation space, the required torque, or specific environmental requirements, we will work with you to find the right solution.

Two-piece shrink discs (torque-controlled) can generally transmit the same torque as three-piece shrink discs and differ only in their design. As standard, two-piece and three-piece shrink discs are used in all areas of friction-fit shaft-hub connections, e.g., in drive technology, the oil and gas industry, the wood industry, or hollow shaft gearboxes.
