Posidyne clutch brakes feature oil shear technology for rapid and precise stopping, starting, speed change and positioning, all without adjustment or maintenance. Suitable for applications with frequent start/stop cycles, these motion control devices allow cycle rates up to 300 cycles per minute. Designed with low-inertia cycling components, the clutch brake requires less motor horsepower to accelerate the load and less torque to stop the load. The totally enclosed design is impervious to dust, chips, chemicals, coolants, caustic washdown and weather, making them ideal for hostile environments. Recirculating the fluid dissipates the heat of engagement, helping to reduce downtime.
