   --1. Airshaft Overall Function:

Multitube Air shaft 019

*Multitube Type Airshaft is a better choice if compared with Lug type Airshaft or Lug type Air shaft. 

Multitube Airshaft have 5 or 6pcs expanding grooves on its surface. After inflation, the full long piece of expanding strip inside the surface will expand.

It has better concentrity and could avoid the jumping problem in some precise cutting using environment.

It has another advantage of reason repairing. For reason of its structure, when this Airshaft need reparing, there is no need to disassemble the whole Air shaft. Just need to loose the locking block on surface, then taking the Expanding element out from the groove, we can replace the Air tube easily. The other Airshafts need to take out the 2 sides, then take away the rubber tube from inside of the Air expanding Shaft body tube.

    --2. Airshaft Feature----Expanding Strip:

       According to the different using situation of customer, we have different expanding strip design. In normal case, we will provide with the NBR rubber + Steel Sheet type Expanding element for Multitube Airshaft. 

         At the same time, we have other material like:

        (1) Full Rubber Expanding Element (without steel sheet)

        (2) Full Aluminum

        (3) Polyurethane 

        (4) Steel 



          We welcome if customers have any other material requirements or dimension design for Pneumatic Shaft!

    --3. Airshaft Body:

      The body is the most important part in Airshaft. 

       Our normal Airshaft body material:



       ---Carbon Fiber

       ---Fully Stainless steel

       Normally for 3inch type, we choose Aluminum tube to make Airshafts for most Market using. 

       For example: 3inch

     2000mm length Air shaft ---- weight load 800kg----use Steel tube

        3300mm length Air shaft ---- weight load 300kg----use Aluminum tube


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

       Our factory is ok to make Multitube 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!

Don't worry weight load and dimension, as a reliable Airshaft Factory, We accept all dimension Air shaft tailor making!

      --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!

        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 Inner Bladder or Inner Tube of the Multitube Airshaft is the most special type.

         For reason of the special structure of the inflatable shaft, it use the Flat TPU tube as the expanding tube.

         Each groove has one pieces Bladder. If one Airshaft have 6 groove, length 1m, then it will use 6m of the Air tube.


          Our company are using high quality TPU raw material, It can ensure the good using of the airshaft.

          Each roll of the Airshaft Inner Bladder is 50m, it is ok for purchasing for spare parts.

           --7. Multitube Airshaft Special Bladder Small Air valve:

              The most interesting part of the Multitube Airshaft is: Except the bigger Air valve on the tube, there is another smaller Air valve inside the TPU tube.


             It is for connection the air, so it quality is also very important.

            In order to improve the quality and ensure the using experience of Airshaft for customer,

         Our company also upgrade the copper matertial in Stainless steel. It has lower possibilty of air leaking!

            --9. What is the advantage of the Multitube Airshaft than Lug type Airshaft?

             Multitube airshafts and Lug type airshafts are both used in the printing, paper, and packaging industries for web handling applications. While both types of airshafts have their own advantages and disadvantages, here are some advantages of multitube airshafts compared to lug type airshafts:


            1. Better control: Multitube airshafts allow for better control of web tension due to their multiple tubes, which   can be individually inflated or deflated to adjust tension.

            2. Reduced slippage: Multitube airshafts distribute the gripping force more evenly across the web, reducing the risk of slippage or wrinkling.

            3. Improved safety: Multitube airshafts eliminate the need for lug rings or spacers, which can pose a safety hazard to operators during setup and maintenance.

            4. Lightweight design: Multitube airshafts are typically lighter in weight than lug type airshafts, which can help to reduce the overall weight of the machinery and improve handling. Because the multitube type airshaft is made by aluminum profile. It can hold the same weight as the steel lug type airshaft.

            5. Low maintenance: Multitube airshafts require minimal maintenance due to their simple design and lack of moving parts. This can help to reduce downtime and repair costs. Customer only need to loose the two sides locker, then can replace the inner air tube directly.

            Overall, multitube airshafts are a reliable and efficient solution for web handling applications, providing better control, safety, and productivity compared to lug type airshafts.
