   --1. Airshaft Overall Function:

Airshaft 23

*Lug type Air shaft is one of the most often used airshafts. It is also known as Lug type pneumatic shaft. It is used in the machines to rewind and unwind the material. It could be applied to different cores materials. For example, paper core, plastic core or steel core......

The lug type airshaft is a specialized mechanical component used primarily in the web handling industry for various applications such as printing, packaging, and converting processes. This type of airshaft is designed to provide secure and precise positioning of the cores, which hold the web material (e.g., paper, film, or foil) during processing.

The cost of the Lug type air expanding shaft is the lowest if compared with other type of airshaft. For reason of its easy inner structure, it could recude the cost of purchasing. It could be used in all using environment.

    --2. Airshaft Feature----Air Expanding Key:

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

    The keys are on the surface of the airshaft tube.

    As a professional Airshaft Manufacturer and Airshaft Factory, We have different type of expanding keys according to different airshafts using situations.

    We have the Air expanding shaft lug made by 






    We welcome if customer want to have different Airshaft expanding key designs

    --3. Airshaft Body:

Airshaft Body Lug Type

       The body is the most important part in Airshaft. 

       Our normal Airshaft body material:



       ---Carbon Fiber

       ---Fully Stainless steel

       According to different weight load of material on airshaft, we will decide the thickness of the body tube.

       For example:

       2000mm steel body tube----weight load 800kg----use thickened tube

       1000mm steel body tube----weight load 500kg----normal tube is ok


       The length of the body tube of the airshafts and the thickness will decide the cost of 1piecAir shaft. 

       Our factory is ok to make Lug 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 examples 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 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 lugs 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.

        --7. Why need to choose Luy type Airshaft? (advantage)

Lug type airshaft is also known as key type airshaft. It is the most often used airshaft. But what is its advantage?

1. Higher load capacity: Lug type airshafts can handle heavier loads than multitube airshafts, making them ideal for applications that require high torque or heavy web tension. We have thickened tube, for example, 3inch lug type airshaft can hold the weight load of more than 2 tons.

2. Lower cost for smaller sizes: For smaller applications, lug type airshafts can be more cost-effective than multitube airshafts, as they require less material and are simpler in design.

3. Reduced vibration: Lug type airshafts can help to reduce vibration during operation, which can improve print quality and reduce wear on machinery.

4. Customerization for overlength size: If customer want to use the bigger diameter airshaft, lug type airshaft can be produced from our standard big sized steel tube. It is more cost effective.

Overall, lug type airshafts still have a number of advantages that make them a viable option for certain applications. It's important to carefully evaluate your specific application needs when selecting an airshaft to ensure that you choose the option that best meets your requirements.
