Key Type Air Shaft is a special rolling or unreeling roller, which is created through high-pressure gas-filled with the lugs on the surface. It introducing foreign advanced production equipment and fabrication technology, using imported balloon, the shaft is casting by aluminum alloy, shaft body plating chromium, accurate assembly, convenient to use and long operating life. When using, match with our company's professional configuration of the aerate gun filling gas for the nozzle jet, to make the shaft of off-axle apperance uniform expansion, thereby lock nitrogen-treated barrel, when unloading, press on deflated mouth to deflated, then nitrogen-treated barrel can be unloaded.
Performance and advantages: Air shaft in practical applications, it has advantages of convenient operation, quick, without damage rolls etc.
Product usage: It is widely used in printing, cutting, coating, compounding and other machineries's releasing and winding scroll.
