Pneumatic brakes, moving, rotating machine parts are used to ensure a shorter time to stop. Working principle of the system is driven by air, the air in the tank and the diaphragm pushes the pusher lugs keeps rotating disk. When the spring comes back through the vent driving and braking operation is terminated. Pneumatic brake goal: keeping constant movement, Hold function, moving mass, the stop function, stopping at certain times of providing an emergency stop function, the specific torque values, making braking function Applications: Iron and Steel Industry Equipments, roll on-winding, tension control and so on. Cable and Wire Winding Machines, Paper Industry, paper tension control, Packaging Machinery, Textile Industry, Cement, Mining, Construction Industry, and are used in a variety of purposes.
