FORTUNE MAKE 1INCH MULTIBLADDER AIR SHAFT

A Cantilever Air Shaft is a specialized shaft designed for easy roll loading and unloading without the need for support on both ends. It is widely used in applications where quick changeovers and efficient handling of rolls are required, such as in slitting, rewinding, and unwinding processes. The shaft operates by inflating an internal bladder, which expands to grip the core securely, ensuring stable and precise web handling. At Fortune Roto Control, we provide high-performance Cantilever Air Shafts engineered for durability, reliability, and ease of use. Our shafts are designed to improve operational efficiency, reduce downtime, and meet the demanding needs of modern industrial applications.

The FORTUNE ROTO CONTROL Leaf Air Shafts are thoughtfully designed and recommended for use with thin-walled cores or narrow cores. Our leaf type air shafts have a wide array of applications and can be used with thin-walled paper, steel, plastic, or fiber cores. FORTUNE’s Leaf Shafts are cost effective and lightweight - delivering impressive performance for you operations.. • Leaf-style design delivers more winding surface, and is best for the elimination of thin wall core deformation

Multi-bladder Aluminium Shaft Operator-friendly due to their lightweight aluminium construction, these shafts can be used for light to medium weight winding operations. Multiple rolls can be wound simultaneously on the same shaft. Multi-bladder Steel Shaft Due to their steel construction, these shafts can be used for heavy-duty winding operations. Multiple rolls can be wound simultaneously on the same shaft. • Perfect for roll unwinding and rewinding process • Body material aluminium with hard Anodized and Steel (NITRIDING STEEL|41CRALMO7 ) with Hardchrome re grinding or Electroless nickel platting • Fortune Centrimax system ensures high precision reel centering to guarantee perfectly concentric unwinding and rewinding. Perfect concentricity allows faster machine speeds and reduces stress on the web material.

Lug Air Shaft or Grippers are slit through the metal pipe and the pneumatic bladder is used for inflating. The grippers give positive holding of the core. These shafts are strong & rigid Standardized design allows us to manufacture the shaft in any size. The same design can be offered for heavy duty to light capability shaft. Simple design ensuring long service Staggered lug design makes it best in the winding application. Each gripper offers a designed chamfer for easy core insertion. Dimensional tolerance of journal is very tight for better fitting & rigidity during operation. Finished with black powder coating OR HCPand electroless platting
