NAB air friction brake's torque will be changed as air pressure, that is mean when air pressure larger, brake's friction pads linked tighter, then its braking force is larger, too. When its braking force is larger than actual needed, rotating part will be stopped completely.

When this NAB air pilot brake used in packaging, printing, coating and other winding unwinding working place, to realized a certain tension force, it can equipped with a electromagnetic valve, producing a certain force, so it is special suitable used for tension control.

Compared with electromagnetic brake, air friction brake is with better thermal capacity and heat dissipation, because its friction plate is like fan shape. This NAB air friction brake is also can be applied in continous slippage situation. HDB Friction brake will not occur problem because of over heat, and its braking torque is stable and will not reduced even temperature is much high.
