Spring Set Holding Brakes

Spring set or electromagnetic release brakes provide braking action via springs when in the de-energized state. As the brake is energized, the load is released and allowed to rotate. Dynacorp spring set brakes are of high quality and are ruggedly engineered for holding applications. Typical applications include medical equipment, robotics, packaging machinery, lifts and motor braking. Use the torque ratings below for sizing/selection.

For smaller sizes, please see Inertia Dynamics' Type SAB Spring Applied Brakes and Type FSBR Reverse Mounted Spring Applied Brakes.
