The pneumatically actuated clutch-brake units from the tried-and-tested series 406 have been further developed to meet the increasing performance and safety requirements in press engineering. The 406 series offers optimally high clutch and brake torques in small dimensions – making it a high-performance compact design. Today, the model series represent the traditional drive unit for stamp and form press engineering.

The hydraulic clutch-brake units from the series 123 work exclusively with Ortlinghaus propretary wet-running, oil-cooled plates with friction pairing steel/ sinter. This multi-plate design and the oil cooled friction pairing of steel and sinter offer a compact design and a high operating efficiency with high torque, low moment of inertia, high engagement frequencies and a minimal need of maintenance. The model series 123 operates in sealed housings which prevent leakage, air pollution and reduce engagement noise to a minimum.

Due to market demands that required higher output capacities of presses, the series 106 was developed from Ortlinghaus. The series 106 clutch-brake unit combines the simplicity of the traditional dry-running clutch-brake unit design with hydraulic actuation. This combination simultaneously achieves highest torques on clutch and brake side which cannot be achieved by engagement through pressurized air. In addition, the design of these clutch-brake units enables the use of two friction plates on the brake side, which allow to use a clutch-brake unit of a smaller size than with other clutch-brake designs. All this leads to a higher number of strokes per minute, a reduced braking angle and a lower individual moment of inertia.
