Product Overview
The XW Machinery Leaf Type Air Shaft Adapter converts a standard 3-inch air expanding shaft into a 6-inch core winding sleeve 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 pneumatic 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 equivalent winding performance more economically and with faster roll changes.
