CANTILEVER PNEUMATIC EXPANDING SHAFTS: HARNESSING THE POWER OF PNEUMATIC TECHNOLOGY: Our pneumatic expanding shafts deliver exceptional torque transmission, making them the ideal choice for roll rewinding and roll unwinding in packaging applications. With a cutting-edge design, these shafts serve as reliable drive shafts, ensuring smooth and efficient operations. Expansion is achieved through a sophisticated system of inflatable chambers strategically positioned beneath each row of expanders, guaranteeing precise control and consistent performance throughout the process. DURABLE CONSTRUCTION MATERIALS FOR EXPANDING SHAFTS Our expandable shafts feature a robust construction designed to meet your specific requirements. The shaft body is available in standard diameters, offering a compelling quality-price ratio with aluminum alloy extrusion. Additionally, upon request, we provide a wide range of steel options for the shaft body, allowing for tailored solutions. The journal ends of our shafts are crafted from AISI 304 steel as a standard material, ensuring strength and reliability. However, we also offer various steel options to accommodate individual needs. The use of aluminum extrusion provides exceptional rigidity, comparable to AISI 304 steel’s modulus of elasticity, enabling the construction of highly rigid airshafts.
