The 2-part shrink disc (torque-controlled) is an external clamping element consisting of a pressure ring and a sleeve. By tightening the clamping screw with the specified screw tightening torque, the pressure ring is pulled axially onto the sleeve. By using conical surfaces, the inner diameter of the sleeve is reduced so that a radial clamping force is applied to the hollow shaft. The clamping force applied by the shrink disc connection creates a frictional connection at the contact surface between the shaft and hub. Compared to the 3-part shrink disc, the 2-part shrink disc has a smaller cone angle and a self-locking function. Due to the small cone angle, the sleeve has additional push-off threads which allow the pressure ring and sleeve to be pressed apart during disassembly. The 2-part shrink discs (torque-controlled) do not have a defined clamping travel. This enables them to compensate for a larger fitting tolerance during assembly. The clamping screws of the 2-part shrink disc (torque-controlled) are tightened evenly in sequence until the specified screw tightening torque is reached. When this assembly condition is reached, it is ensured that the torques specified in the catalog can be transmitted. 2-part shrink discs (torque-controlled) are available in various designs. Depending on the installation space available to you, the required torque or special environmental requirements, we will work together to find the right solution for you.

The 2-part shrink discs (torque-controlled) can generally transmit the same torque as 3-part shrink discs and differ only in their design. As standard, 2-part shrink discs are used in the same way as 3-part shrink discs in the entire area of frictionally engaged shaft-hub connections, e.g. in drive technology, the oil and gas industry, the wood industry or hollow shaft gearboxes.
