Technical Details 
Engineered for Versatile Roll HandlingOur air expanding shafts are crafted to facilitate seamless rewinding and unwinding processes in industrial environments. With compatibility across different core sizes and types, along with robust load capacities, these shafts excel in both cantilevered and supported installations. Their smooth, chrome-plated or anodized surface ensures durability and resistance against corrosion, making them ideal for a variety of materials and conditions.
Precision Manufacturing for Consistent QualityManufactured with industrial-grade steel or aluminum, each shaft boasts tight tolerancesroundness 0.02 mm and precision up to 0.01 mmensuring high performance in demanding applications. Features such as adjustable expansion stroke (up to 18 mm) and a wide operating temperature range (-10C to +55C) enhance their adaptability. Customization options cater to specific industry needs, with low-maintenance designs for maximum convenience.
FAQs of Air Expanding Shafts:
Q: How do air expanding shafts function during the roll rewinding process?
A: Air expanding shafts use inflatable elements within the core to securely grip and expand into the rolls inner diameter when air is applied (up to 6 Bar). This provides firm holding during rewinding and unwinding, reducing slippage and ensuring accurate material handling.
Q: What types of cores and mounting styles are compatible with these shafts?
A: These shafts are compatible with lug, leaf, and multi-bladder core types and come in supported or cantilevered mounting styles. They can be fitted with 3, 6, 8, and 10 cores, with custom sizing available for specialized applications.
Q: When should I choose a multi-bladder shaft over a lug or leaf type?
A: A multi-bladder air expanding shaft is ideal when you require precise, uniform expansion for delicate or sensitive materials. Lug and leaf types suit general applications where robust grip is needed for heavier or standard rolls.
Q: Where can these shafts be utilized within industrial processes?
A: These shafts are commonly used in industries like paper, film, foil, and textile manufacturing, where accurate and efficient rewinding or unwinding of rolls is required. They are suitable for production lines operating in temperatures from -10C to +55C.
Q: What is the maintenance process and are parts replaceable?
A: Maintenance is minimal due to the robust, corrosion-resistant construction. If needed, components such as air bladders or lugs are easily replaceable, extending the service life of the shaft and reducing downtime.
Q: How does customization benefit customers needing specific shaft requirements?
A: By offering custom sizes, colors, materials, surface treatments, and end fittings (such as flange or journal types), customers can obtain air expanding shafts optimized for their precise production parameters and machinery, enhancing operational efficiency.
