Miki Pulley Safety Brakes
Miki Pulley safety brakes ensure maximum reliability in safety-critical applications. As spring-actuated brakes, they are energy-efficient and reliably secure machines and axes in the event of a power failure. They are power-off engaged (fail-safe): when de-energized, the springs automatically engage and lock the shaft. This offers a high level of safety during emergency stops, power failures, or in safety-critical applications. This makes them ideal for servo motors, robotics, and precision machines.
