The Mayr ROBA®-servostop® Size 120 Type 898.002.00S Electromagnetic Safety Brake (Drawing Ref: Z7129838 / Part No.: 8229619) is a high-performance spring-applied holding brake engineered by Mayr (Germany) specifically for integration into servo motors and high-dynamic automation systems.

Operating on the fail-safe principle, the brake engages mechanically via spring force when electrical power is removed or interrupted, instantly clamping the motor shaft to hold loads securely in place and prevent vertical Z-axis drop. When 24VDC power is supplied, the electromagnetic coil counteracts the spring force, releasing the brake rotor and allowing unobstructed motor rotation. Providing a robust 32 Nm nominal braking torque within an exceptionally slim profile and low mass moment of inertia, the ROBA-servostop Size 120 delivers backlash-free torque transmission, fast engagement times, and maximum operational safety for robotics and CNC machine tools.
