A shrink disc unit including a rotating body with a peripheral outer surface and a hub surrounding the rotating body with a peripheral inner surface. The peripheral inner surface and the peripheral outer surface form a separating line between the rotating body and the hub at an angle to a rotational axis of the rotating body. A fluid channel leads through the rotating body or the hub for pressurization of the separating line with a pressure fluid. A fixing device, formed from one of the rotating body or the hub, alone or in combination with the other, may be used to fix a tool for the assembly or disassembly of the hub at a given angular position on the rotating body and/or the hub.
