Lug type pneumatic expandable shaft can be made with both end loading and one end loading two modes. These two modesl pneumatic expandable shaft can meet customer's high-intensitive and high torque requirement, it is also can bear heavy loading coil material. Through single tube expanded, keys expanded, so as to grip and withstand paper core tightly.
Shaft body can be made with steel and aluminum material. As usually, keys are made with steel, if you have special requirement, keys are also can be made with rubber or other materials accordingly.
Pneumatic expandable shaft is widely applied in slitting, printing, packing, winding & rewinding, coating, laminating machine and other high circle or surface coiling machineries.
According to shaft material, this pneumatic expandable shaft can be divided into steel and aluminum two materials. As usually, the steel material pneumatic expandable shaft loading weight is heavier than aluminum material pneumatic expandable shaft. So for the large or heavy coil winding and rewinding, steel material pneumatic expandable shaft is a better choice. If the winding and rewinding coil is light, aluminum material expandable shaft is light for working, and surface looks beautiful.
On the other hand, the steel and aluminum material pneumatic expandable shaft both can be made with lug and strip types. It is according to its customer's requirement.
Handong company is a professional and outstanding manufacturer of air shaft. This pneumatic expandable shaft can be customized, such as material, body diameter, body length, total length, shaft end shape, shaft end length and etc.
Aluminum alloy or steel air shaft with hard chrome-plated surface. Air shaft has the advantage of easy paper tube placing, economic, short charging time, heavy loading, simple maintenance and long service life and etc. It is widely used in printing machinery, paper making machinery and other winding and unwinding machine. It can be match with brake, clutch, pedestal safety chuck, tension controller and so on.
