NAC model air shaft clutch is linked with air pressure, released by return springs. Disc relies on air pressure to slide along the direction of the axis, contacting the friction plate. Disc, friction plate and so on, are assembling to the wheel to come into an integrated structure. This NAC model air shaft friction plate clutch can replace HDC model friction disc clutch well. This air shaft clutch is widely used in rubber machine rollers, conveyor, elevator, handling machinery, food machinery, printing machinery, crusher, motor, tire and rubber machinery, packaging machinery, forming machinery, automatic machinery, wire machinery, sheet metal machinery, filling machinery, plywood machinery, medical machinery, stretching wire� machinery, fiber machinery, metalworking machinery,� pulverizing machinery, tire forming machinery, paper making machinery and etc.
