Short description
The XW Machinery Leaf Type Air Shaft Adapter is designed to convert standard 3-inch air shafts into 6-inch core winding systems for industrial rewinding and unwinding applications. Manufactured from high-strength aluminum alloy with precision machining and hard anodized treatment, this pneumatic core adapter provides stable expansion, accurate roll positioning, and reliable torque transmission during high-speed operation.

What is a Leaf Type Air Shaft Adapter?
A leaf type air shaft adapter is a pneumatic sleeve installed over a 3-inch air expanding shaft to allow it to handle 6-inch paper cores or plastic cores. Instead of purchasing a separate 6-inch air shaft, operators can use a lightweight adapter to achieve the same winding function more economically and efficiently.

Also known as

• Pneumatic core adapter
