Used for tightening locking screws, the pressure rings are pulled together to compress the inner ring, creating pressure on the outer surface of the shaft.
– Featuring a lightweight design, the shrink disc is placed around the hollow shaft to provide concentric connection, suitable balance for high-speed applications, and space-saving. It is easy to replace and install.
– When the locking screws are tightened, the contact surfaces are pressed together to prevent the ingress of dirt and moisture. The inner ring has grooves to minimize pressure and force on the hollow shaft and shaft. Suitable for both static and dynamic loads.
