3 Inch & 6 Inch Steel Air Shaft Core Adapter

The XW Machinery Steel Air Shaft Core Adapter is designed for converting 3-inch and 6-inch roll cores in industrial winding and unwinding systems.

Manufactured from high-strength steel with precision machining, this heavy-duty core adapter provides stable torque transmission, accurate roll positioning, and reliable operation in high-speed converting applications.

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

What Is an Air Shaft Core Adapter?

An air shaft core adapter is a converting component used to adapt different paper core sizes on pneumatic air shafts and rewinding systems.

It allows operators to quickly switch between different roll core diameters without replacing the entire air shaft system.

Core adapters are commonly used for:

• 3-inch to 6-inch roll conversion
• Rewinding systems
• Slitting machinery
• Printing machines
• Film converting lines
• Flexible packaging equipment

These adapters improve production flexibility and reduce machine downtime during roll changes.
