Air Expanding Shafts for Winding & Rewinding Applications

  Air shafts, also known as air expanding shafts or pneumatic shafts, are essential components for secure core gripping, efficient roll handling, and stable winding performance in modern converting equipment. XW Machinery manufactures high-performance air shafts designed for printing, packaging, paper, film, textile, lithium battery, coating, laminating, slitting, rewinding, and unwinding applications.

  Our comprehensive product range includes slat type air shafts, key type air shafts, continuous long-key air shafts, and manual expanding shafts to meet different production requirements. Slat type air shafts provide uniform 360-degree core expansion for lightweight and thin-wall cores, while key type air shafts deliver superior torque transmission for heavy-duty winding operations. Long-key air shafts are ideal for multi-roll and multi-slit applications requiring consistent gripping performance across varying core widths.

  Manufactured from aviation-grade aluminum alloys, precision steel components, and durable inflatable bladders, our air shafts offer excellent concentricity, high load capacity, and long service life. Designed for stable operation at high speeds, they help improve winding quality, reduce downtime, and increase overall production efficiency.
