ABSTRACT:
A device for supporting and for at least contributing to the activation of an actuating element. An outer thin-walled bearing ring defines a pressure space to which pressure is applied. The outer thin-walled bearing ring at least partially bounds a circumference of the pressure space. A piston supports the actuating element and moves longitudinally within the pressure space with respect to the outer thin-walled bearing ring. Roller bodies configured to roll on the outer thin-walled bearing ring for supporting the actuating element.
