Aluminum lug type air expanding shaft for roller material

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.

Air shaft working theory and main characters:

1.Air pressure shaft also called air shaft, it uses air pressure changing shaft outside diameter size, so as to closely touch with reel pipe. So as to convenient whole roll material winding and unwinding, making production line operation reasonable, convenient, precious and automatic.

2.When air inlet, shaft inner expanded, components of inner shaft expanded, the shaft outside diameter increase, so the reel pipe touched with shaft closely. When air outlet, expanded components withdraw, shaft can be taken out easily.

3.Shaft core uses high stress steel or aluminum alloy, internal expand components adapts import synthetic rubber, and has various structure types: Strip Type Airshaft, Lug Type Air Shaft, Multi Bladder Airshaft.
