Magnetic powder clutch, brake

Magnetic powder clutches and brakes transmit torque via high-permeability magnetic iron powder, combining the flexibility of fluid couplings with the high efficiency of friction clutches during engagement and startup. Our products have been extensively field‑tested by numerous machinery manufacturers, accumulating substantial production and technical expertise to meet a wide range of customer requirements. They are indispensable for tension control in applications such as winding and unwinding paper, wire, printing substrates, and various film slitting processes, while also serving as buffering devices for smooth starts and overload protection systems.

Air-expanding shaft

Air‑inflated shafts are primarily designed for use in unwind and rewind operations across a range of machinery, including film blowing, printing, slitting, coating, laminating, bag making, and papermaking.
