3 Inch to 6 Inch Plate Type Air Shaft Adapter

The XW Machinery Plate 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.

It is widely used in slitting machines, printing machinery, flexible packaging equipment, coating systems, film converting lines, and paper processing machinery.

What Is a Plate Type Air Shaft Adapter?

A plate 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.

This adapter is also known as:

• Pneumatic core adapter
• Air drum
• Air cover
• Rewinding core adapter
• Air shaft sleeve adapter

Key Features

• Converts 3-inch shafts to 6-inch core systems
• Plate type expanding structure
• Lightweight aluminum alloy body
• Stable pneumatic expansion
• Hard anodized surface treatment
• Easy installation and removal
• Reliable torque transmission
• Excellent wear resistance
• Suitable for high-speed rewinding
• Custom sizes available

Applications

This plate type air shaft adapter is widely used in:

• Slitting machines
• Rewinding systems
• Flexographic printing machines
• Rotogravure printing equipment
• Film converting machinery
• Coating machines
• Paper processing systems
• Plastic film production lines
• Foil rewinding equipment
• Flexible packaging machinery

Industry references also show these adapters are commonly used in coating, printing, rewinding, papermaking, plastics, and converting systems.

Advantages of Plate Type Adapters

Compared with traditional heavy 6-inch air shafts, plate type adapters provide:

• Lower equipment cost
• Faster roll changes
• Reduced shaft weight
• Easier handling
• Better production flexibility
• Reduced downtime

Many industrial converting systems use adapters instead of dedicated large shafts to improve operational efficiency.
