6inch Inflatable leaf type Air Expanding Shaft
It is specifically used in paper coating, printing and other industries. , Unwind the reel. After compressed air is inflated, the key bar on the shaft surface can protrude (the shaft diameter is increased), and the key bar on the surface is quickly retracted after the air is deflated (the shaft diameter is restored) to tighten the cylinder core.

Air expanding shaft Performance & Advantage:
In practical applications,it has advantages of convenient operation,quick, air shaft has big stress area, the stress distribution uniformity etc.
The 6inch leaf type air shaft is suitable for unwinding and rewinding of related machinery such as coating, composite, paper making, bag making, plastic, etc. It is especially suitable for occasions where the paper tube has high roundness requirements or the surface retracting roll is used,as a result,work efficiency and product quality on equipment can be improved.
In general, the main core tube and shaft head of the pneumatic shaft are made of steel; the raw material of the external pressure plate is aluminum alloy, which can be treated with hard oxygen according to customer requirements; and the method of external pressure plate is mainly There are two types: toothed and smooth. The toothed type is commonly used.

What problems should be paid attention to when using slatted air expansion shaft?
a. It is necessary to insist that the air pressure in the air shaft is still sufficient;
b. Keep the surface of the pneumatic shaft clean to prevent debris from getting stuck in the outer pressure plate and deforming it and affecting its use;
c. The pneumatic shaft must be placed horizontally when not in use, and should not be suspended or erected to avoid deformation of the external pressure plate due to collision;
d. Because the outer pressure plate is made of aluminum alloy, it is not suitable to knock with heavy objects during use to prevent deformation.
e. When winding or unwinding, if there are parts at both ends that are not covered by the core, use an empty core to cover the empty part;
