   --1. Airshaft Overall Function:

Leaf Type Airshaft 01

Leaf type Air shaft is suitable  for unwinding after slitting/cutting and cantilever single shaft winding. 

The leaf one the Airshaft is able for expanding. It is more stable and can provide a balance during the rotation.

For this reason, this type Air shaft has a longer using time.

The expanding Leaf the Leaf Type Airshaft is made by aluminum,

The inner tube in normal is steel, aluminum is also ok for using.

    --2Airshaft Feature----Air Expanding Leaf:

    The Leaf type Air Shaft is also known as Airshaft with expanding Leaf.

     The leaf is on the surface of the tube.

    As a professional Airshaft Manufacturer and Airshaft Factory, We provide high quality Airshaft expanding Leaf.

    --3. Airshaft Body:

Leaf Type Airshaft 03

       The body is the most important part in Airshaft. 

       Our normal Airshaft body material:



       ---Fully Stainless steel

       In normal case, We use Steel as the inner body tube.

                                                                            Some customer's weight load is smaller and want to reduce shaft weight, in this case, we recommend inner tube by fully aluminum.


       The length of the body tube of the airshafts and the thickness will decide the cost of 1piece Air shaft

       Our factory is ok to make Leaf type Air shafts at any length and any diameter.

       Just  need to give us a drawing and tell us the weight load!

       Then we can help any things related with air expanding shaft!

      --4. Airshaft 2 sides:

      The 2 sides of the Airshafts are the most interesting parts of Airshaft Design. It is usually the assemble             position of the Air expanding shaft.

      We have a lot of drawing example for customer reference.

      We have can make the 2 sides of the Airshafts according to requirements!

       --5. Airshaft Inflation air valve:

       The Air inflation valve of the pneumatic shaft is one of the most important things in it.

        If the Air shaft using poor quality air valve, then it will often leaking air, and then result into using trouble!


        Normal Airshaft Suppliers are using the copper material air valve in order to saving cost,

        However, This type Copper Valve have a higher possibility of air leaking,

        For us, we are using the high quality Stainless Steel Air Valve, it is more more stable in quality!

Normal Copper Air valve for Air shaft


        We don't want to see the machine stop production just for reason of a small Air valve.

        Therefore, a good AirShaft with better Air Inflation Valve will help users to avoid a lot of using troubles.

        We Guarantee the long time using of Air inflation Valve on the Airshaft!

           --6. Airshaft Inflation Inner Bladder:

          The Airshaft inner bladder is the air bag of the whole Air expanding shaft.

            The air will go through into the Black Rubber tube, then expand the whole lugs to grab the core on                          airshafts.

             If the airshaft inner bladder have low quality, it will result into the uneven expanding. It means most part                 of the Leaf are not expanding.

             As a result, the Air shaft cannot hold the core. It would caused big trouble, need to disassemble the whole               airshaft to replace this parts. (Time consuming and wasting)



          So, our company are using high quality NBR Rubber, It can ensure the good using of the airshaft.
