Spring Applied Brakes are designed to decelerate or park inertia loads when the voltage is turned off. Type SAB is designed to be engaged and disengaged in a static condition at zero RPM. These brakes can be mounted to a flange or motor using thru-holes or tapped holes in the field cup. The brake incorporates a lever, which is rotated to mechanically engage the clapper plate. The clapper plate acts against the compression springs and allows the armature disc to spin freely.
