Details

Structural Principle: Utilizing a through-type inflation tube, gas is evenly distributed throughout the entire shaft, ensuring synchronized operation of the expansion elements and more stable clamping.

High-Strength Design: The shaft is constructed from high-strength steel or aluminum alloy, possessing excellent bending resistance and durability.

Excellent Airtightness: High-quality internal seals ensure sustained and stable air pressure over extended periods.

Suitable for Multiple Roll Sizes: Compatible with various outer and inner diameters, supporting quick loading/unloading and size changes.

Easy Operation: Rapid inflation and deflation, suitable for frequent roll changes, significantly improving production efficiency.

Applications: Widely used in winding systems for films, paper, non-woven fabrics, aluminum foil, packaging materials, etc., ensuring uniform roll tension and smooth operation.
