Abstract
An actuating device for a coupling/braking device is provided with at least one actuating piston that is axially slidable relative to a shaft and, in an actuating state, exerts an axially acting contact pressure on coupling/braking parts of the coupling/braking device. At least one control piston is provided that axially displaces the at least one actuating piston into the actuating position. A coating is provided in a contact region between the actuating piston and the control piston, wherein the coating is disposed at the actuating piston or at the control piston or at both the actuating piston and the control piston. The actuating piston can also be designed as a control piston that interacts immediately with the coupling/braking parts of the coupling/braking device.
