Product Overview:
 

Shrink discs are removable machine elements used for to connect a hollow shaft with a solid shaft. The assembly is hydraulically pre-loaded under high pressure using a hand pump. The self-locking tapered joint being secured with a retaining ring. Assembly and removal of these takes only a fraction of the time usually taken for bolt type Shrink Discs.

The main function of a shrink disc is the safe connection of a shaft with a hub by means of friction. For example, between a drive shaft and a transmission hollow shaft. The shrink disc generates a backlash-free connection by pressing the hub onto the shaft. This connection is mainly used to transmit torque. The shrink disc only provides the required forces, and transfers no forces or moments between shaft and hub by itself. Therefore, the force flow does not pass through it.
