Pneumatically operated multi-disc clutch
Engaged by compressed air - axial or radial supply through the shaft. Opened by spring pressure (in special cases vice versa), free from axial forces requiring less maintenance small teeth backlash with the discs  excess service pressure 5.5 bar torque 120 to 60000 Nm (higher torques on request) wet operation or dry operation possible by selection of suitable disc combinations outer diameter 114 to 640 mm several friction faces - low residual torque in open condition small dimensions high torques high heat capacity
