Air Expanding Shaft

An air expanding shaft is a pneumatically actuated expandable shaft designed to give fast, secure and even gripping of cores and sleeves during high-speed winding and unwinding applications. This state-of-the-art solution offers better holding power with instant release speeds in converting, printing, packaging, and textile industries that require quick roll changes and accurate core centring to maximise productivity and minimise downtime. Typical applications include core mounting in slitting and rewinding machines, roll support in flexographic printing presses, material handling of laminating and coating equipment, etc. without manual effort or complex mechanical changes. Air expanding shafts are constructed of lightweight aluminium and offer precision-built expansion chambers, along with robust rubber gripping elements for reliable performance and long service life. The advanced pneumatic design allows air-expanding shafts to offer even, radial expansion with consistent clamping force while providing instantaneous release capabilities for smooth and rapid roll changeovers and providing emergency stop in the event of a web break or machinery failure. In addition, they offer flexible capability for different core diameters and roll widths with standard compressed air requirements for compatibility with existing pneumatic installations.
