Pneumatic Differential Air Shaft: An Essential Tool for High-Quality Winding

A pneumatic differential shaft is a type of differential shaft that uses compressed air to provide adjustable tension to the material being wound.

carbon fiber prepreg

It is designed to address the issue of uneven material surfaces, which can affect the quality of winding using an air expanding shaft.

The pneumatic differential shaft consists of a shaft, air bag, friction strip, and slip ring, which work together to provide independent tension control for each ring.

differential friction shaft component

It is available in different ring sizes ranging from 10mm to 50mm and can be supplied in various shaft sizes, including 3-inch, 6-inch, 8-inch, 10-inch, and 12-inch.

Winding is a crucial process in the production of many industrial materials such as paper, film, foil, and textiles.

One of the key challenges in winding is maintaining constant tension on the material to ensure a smooth, uniform surface.

Uneven tension can result in defects such as wrinkles, telescoping, and baggy edges, which can affect the quality and performance of the product.

To address this issue, manufacturers use pneumatic differential air shafts, which provide a reliable and efficient way to maintain tension during winding.

What is a pneumatic differential air shaft?

A pneumatic differential air shaft is a mechanical device that uses compressed air to provide adjustable tension to the material being wound.

It consists of a hollow cylindrical shaft with a series of air bags or bladders along its length.

When the shaft is rotated, the bags inflate and deflate in response to changes in air pressure, providing a constant, even tension to the material.

How does a pneumatic differential air shaft work?

The working principle of a differential air shaft is based on the interaction between the torque groups and the air pressure.

Each torque group consists of a set of leaf springs or rollers that transmit the torque from the shaft to the material being wound.

Compressed air enters the interior of the air bag, causing it to expand and push each torque group outward.

The sliding torque value of each torque group can be adjusted according to the size of the inflation pressure, which allows for precise control of the tension on each roll of material.

Advantages of using a pneumatic differential air shaft

One of the main advantages of using a differential air shaft is that it provides consistent tension across the entire width of the material, regardless of variations in thickness or density.

This is because the tension is controlled by the air pressure, which is distributed evenly across the surface of the air bags.

In addition, differential air shafts are easy to install and require minimal maintenance, making them a cost-effective solution for many applications.

Another advantage of differential air shafts is that they can be used with a variety of materials and winding configurations.

They are commonly used in slitting machines, rewinders, and laminators, and can accommodate a range of roll diameters and widths.

They are also compatible with many types of material, including paper, film, foil, and textiles.


In summary, a differential air shaft is an essential tool for achieving high-quality winding in industrial applications.

By providing consistent, adjustable tension to the material being wound, differential air shafts can improve the surface quality, reduce defects, and increase productivity.

With their reliable performance and versatility, differential air shafts are a valuable investment for manufacturers seeking to optimize their winding processes.
