Quick Loading/Unloading and Efficiency Improvement Achieve rapid fixation and detachment of roll materials through inflating/deflating operations (only 2-3 seconds), significantly reducing downtime and meeting high-frequency roll change requirements. No complex mechanical operations or tools required, lowering manual labor intensity, especially ideal for automated production lines.

High-Precision Positioning and Consistency After inflation, the shaft tightly adheres to the inner hole of the roll material, ensuring concentricity and uniform tension, preventing misalignment or loosening, and improving finished product quality in processes like printing and coating. Key-type expansion shaft design distributes force application points, balances load pressure, and suits heavy-duty scenarios (e.g., fabric, metal rolls).

Flexibility and Broad Applicability Customizable dimensions (length from hundreds of millimeters to over 6 meters, shaft diameter 1-12 inches), adapts to various roll materials of different thicknesses, widths, and specifications. Applicable to multiple industries including printing, papermaking, packaging, textile, and plastic processing, covering both light and heavy industrial needs.

Durability and Easy Maintenance Utilizes high-quality steel materials and chrome plating for wear and corrosion resistance, ensuring long service life. Modular design with interchangeable components simplifies repairs and reduces costs; routine maintenance involves checking air tightness, cleaning, and lubrication.

High Load-Bearing Capacity Steel materials selected based on requirements enable a single shaft to bear over 1 ton, meeting heavy industrial demands.

With more than 17 years of experience in all areas of modern winding technology, we are the first point of contact in china for pneumatic and pneumo-mechanical air shafts. We offer expansion shafts for every application, friction shafts or adapters. standard solutions or manufactured on customers request.

Material: No.45 steel/ Aluminum
Length: 0.2m-3.8m

The lightweight aluminium air shafts is the right choice for most standard applications. It is designed for medium web tension and medium coil weight. Due to the aluminium profile design, the air shaft is extremely light and relieves the machine operator during frequent roll changes. The pneumatic clamping shaft expands by a flat hose system. The continuous clamping bars are very protective to the cores and allow even a winding of multiple cores.

Due to its construction and the central tube system, this winding shaft is the most customisable. Depending on its design, it can withstand very high loads and is therefore a real high-performance air shaft. Even a carbon fibre body is possible in case a very low dead weight is required. The shafts expansion elements are expanding by a central rubber hose.
