Air shaft is a special shaft for winding and unwinding. The shaft is created by the key on the surface, which will be expand when the high-pressure gas filled in the shaft. Air shaft is easy to operate, the user only have the air supply with the air pressure controlled within 6-8kg/cm2. Just aired the shaft through the air valve and when user want to lock the web. Just push the core activities of the air valve to deflate, the keys will revert to its original appearance, then web can be removed easily.

1. What is Air Shaft
It is a kind of special-made shaft for winding or unwinding, when it inflated by high-pressure, the surface of it can be raised up
and after deflating the air,the surface will quickly retract.It is widely used in the manufacturing process and light metal industry.The advantage of using an air shaft is that it can greatly improve the working efficiency.
2. What can an air shaft be used for?
- Air ePrinting machine;
- Cutting machine;
- Slitting machine;
- Coating machine;
- Laminating machine;
- Bag making machine;
...etc.
3. Specifications of air shaft
Type: Key type air shaft(steel-made or aluminum made), Lath type air shaft, Differential air shaft
Material: No.45 steel/ Aluminum
Length: 0.2m-3.8m
Expanding shaft brief introduction:
The air shaft (inflatable shaft) introducing foreign advanced production equipment and fabrication technology, using imported airbag, shaft head for the high quality steel products with precise process, attribute wattle using excellent aluminum and hard oxide, use convenient and long operate 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 appearance uniform expansion, thereby lock nitrogen-treated barrel,when unloading, press on deflated mouth to deflated, then nitrogen-treated barrel can be unloaded.
Air expanding shaft main feature:
1. Material and technology from Taiwan .
2.Factory directly supply.
3.Extensive application and high precision performance.
4.Simple installation.
5.Durable.
6.All specification can be customized.
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.
1. Inflatable job a short time, separated from the inflatable Key type air shaft and place the paper tube just three seconds to
inflate and deflate, nor do they need any parts sub negligent shaft side that is able to work closely with the paper tube bite.
2. Paper tube placement simple: inflatable and deflated operation, mobile and fixed any position paper tube in the axial plane.
3. Carrying heavy: May be the actual needs of customers, to determine the size of the shaft diameter, and the use of high
strength steels hard to make it carry the weight increase.
4. Economic efficiency: shaft design for a particular function, for thick, thin, wide, narrow tubes have encountered all kinds of
paper of all applications.
5. Maintenance is simple, use a long time: a single film blowing machine inflatable Key type air shaft parts, each part in its
construction fixed specifications, can exchange it with, it is convenient.
Air expanding shaft Product Purpose:
It is applicable to winding and unwinding shaft of the related machines in coating,cutting,printing,compounding,paper making,bag making,plastic items,specially the occasion of the high-efficient roundness required or surface winding and unwinding of the paper tube.Moreover,it also can improve efficiency and quality of the products.

Thermocouples are a widely used type of temperature sensorfor measurement and control,and can also convert a temperature gradient into electricity. When two wires composed of dissimilar metals are joined at both ends and one of the ends is heated, there is a continuous current which flows in the thermoelectric circuit. If this circuit is broken at the center, the net open circuit voltage (the Seebeck voltage) is a function of the junction temperature and the composition of the two metals. Which means that when the junction of the two metals is heated, or cooled, a voltage is produced that can be correlated back to the temperature.
