This magnetic powder brake is widely applied in rewinding and unwinding machine for tension control or stop, such as face mask machine, non-woven fabric machine, packing and printing machine...
Its braking force is different as its model. As usually, there are some models of this magnetic powder brake, including PKB-0.6, PKB-1.2, PKB-2.5, PKB-5, PKB-10, PKB-20 amd etc. Their braking torque is from 6N.m to 200N.m.



In this case, magnetic powder brake is applied in film or paper unwinder. Through adjust its electricity, so as to regulating its braking force accordingly.
