Technical Details 
Precision Engineering for Reliable Core HandlingOur Lug Type Air Expandable Shafts are meticulously machined to 0.01 mm accuracy, ensuring excellent roundness ( 0.01 mm deviation) and high performance. Designed for demanding industrial environments, these shafts offer superb core grip and dynamic balance for smooth, vibration-free operation at high speeds.
Versatile Compatibility and CustomizationChoose from a variety of sizes, lug counts, and valve types to suit your application needs. Standard diameters include 3" (76 mm) and 6" (150 mm), with lengths from 300 mm up to 6000 mm. Our shafts are compatible with paper, plastic, and metal cores, enhancing flexibility for diverse industries.
Low Maintenance and Durable ConstructionBuilt with high-strength steel alloy and a choice of hard anodized or chrome plating, these shafts boast a polished texture with lug grooves to ensure smooth and long-lasting operation. The lugs are easily serviceable, providing extra convenience and extended service life.
FAQs of Lug Type Air Expandable Shaft:
Q: How does the Lug Type Air Expandable Shaft secure different core materials?
A: The shaft expands its lugs outward when air is supplied (47 Bar) using push, flap, or fixed inflation valves. This creates a secure grip on paper, plastic, or metal cores, ensuring stable rotation and preventing slippage during high-speed operations.
Q: What is the process for installing and inflating the shaft in a machine?
A: To install, choose either end or center shaft mounting as needed, insert the shaft into the core, and connect your air supply to the designated inflation valve. Inflate to the recommended pressure (47 Bar) until the lugs fully expand, then lock the shaft in place for safe and reliable operation.
Q: When should the lugs be serviced or replaced?
A: Lugs are designed for long-term use with low maintenance. Inspection is recommended during routine machine maintenance. If you notice grip loss or uneven expansion, servicing or replacing the lugs will restore optimal performance.
Q: Where are these air shafts mainly used?
A: Our lug type air expandable shafts are widely utilized in printing presses, laminators, slitters, rewinders, and packaging machines, supporting efficient web handling and material changeovers across manufacturing industries in India and export markets.
Q: What are the benefits of using a dynamically balanced shaft?
A: Dynamic balancing minimizes vibration at operating speeds up to 2500 RPM, leading to smoother machine operation, reduced wear on bearings, and improved product quality during high-speed processing.
Q: How customizable are the shaft length and diameter?
A: Shafts are available in standard diameters of 3" (76 mm) and 6" (150 mm), or can be custom-made. Lengths range from 300 mm to 6000 mm, ensuring a fit for nearly any core size or machine requirement.
