Air shaft is a machine part or shaft which tightens the core or roll on filling air. Air Shafts are of two types: Contains Inflatable Rubber tube inside also called Lug shafts.

The multi-bladder strip air shaft is our most popular air shaft, allowing for a variety of gripping ledges to handle all types of applications. Its rugged design is available in three body materials: aluminum, steel and carbon fiber, making it suitable for …

Using the Air Shaft, the slitting machine fabricates large rolls of material into smaller rollers and pieces. The latest technology embeds a brilliant feature into the device, it’s efficient to amend according to speed variations and core widths.

Air Shafts, also commonly known as Air Bars or Air Mandrels, are used in the manufacturing processes for fitting into a core onto which materials such as paper, card and plastic film are wound. An Air Shaft is designed so that, on fitting into a core, it can be readily expanded, thereby achieving a quick and firm attachment.

Mar 9, 2020 · An airshaft (or air expanding shaft) works by pumping its internal air shaft bladder which pushes out the external gripping Lugs/Leaves/rubbers to hold onto the materials from their core. By releasing the air, the gripping medium un-grips the materials, allowing easy replacement.

Oct 16, 2023 · A well-designed air shaft that makes repairs quick and easy could be the difference between pausing production for days and resuming operations quickly. The good news is that a proper air shaft design that makes it easy to access the bladder can help you save time and money on maintenance.

Sep 9, 2024 · Air shaft, also known as an inflatable shaft, is a type of mechanical device used for storing, transporting, and handling rolls of materials such as paper, plastic film, fabrics, or similar products.

In simple language, it is a metallic tube. In industry circles, it has also become popular as air bars or air mandrels, or an air expandable shaft. The important product is designed and configured to adjust to the speed of variations and different core widths.

Mar 21, 2025 · An air shaft (also termed air mandrel, air expanding shaft, or pneumatic core) is a critical mechanical component widely used in manufacturing processes requiring precise winding, unwinding, or slitting of materials such as paper, plastic film, textiles, and metal foils.

Mar 3, 2025 · An air expanding shaft is a mechanical transmission device that can control the transmission capacity of the shaft by inflating and deflating. Generally speaking, the outer diameter of the inflatable shaft will be enlarged after inflation, and then the inflatable shaft will be sleeved into the coil, and the coil will be tightened.
