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.
