Prot.act – Hydraulic brake | Series 171. Ortlinghaus Quality.

Series 171

Servo brake Prot.act

With the Prot.act model series, Ortlinghaus has developed a hydraulically released and spring-loaded brake with dry-running friction elements specifically developed for servomotor-driven presses. The brake is normally used as a holding brake for stationary machines, but can also be used as a safety brake for emergency stops.

The brake is characterized by its minimal space requirements, low moment of inertia of the parts rotating with the drive motor, and short switching times. Thanks to its enclosed design, the brake also produces little external pollution and minimal noise. It conforms to the European safety standard DIN EN 692 and is largely maintenance-free. 


Due to the design format with friction blocks, the axial mobility of the friction elements when operating the brake is possible without moving metallic contact points. Thanks to the dry-running principle, no undesired residual torque develops during normal operation of the press with the brake open. 

With the Prot.act servo brakes, we have designed two size variants (Prot.act 90 & Prot.act 94) for integration in front of the Siemens high-torque motors 1FW3 and 1FW4. The Prot.act flanges are exactly the same dimensions as the Siemens motor flanges, which allows a slim but compact and robust drivetrain combination.
