TECHNO CNC presents the Air Shaft Adjustable, a precision-engineered pneumatic expanding shaft designed for efficient handling of rolls in industrial converting, winding, and unwinding applications.
This air shaft operates using compressed air to expand internal lugs or strips, allowing it to securely grip the inner core of rolls such as paper, plastic films, aluminum foil, laminates, and textiles. The adjustable design enables compatibility with multiple core sizes, making it a versatile solution for various industrial machines.
Manufactured from high-strength steel or lightweight aluminum alloy, the shaft provides excellent durability, load-bearing capacity, and long operational life. Its precision-machined structure ensures smooth rotation, proper alignment, and vibration-free performance during high-speed operations.
Air shaft adjustable systems are widely used in slitting machines, rewinding machines, printing presses, lamination machines, and packaging equipment, where secure roll holding and quick changeover are critical for productivity.
The easy inflation and deflation mechanism allows fast roll mounting and removal, reducing downtime and improving operational efficiency.
