Product Description
Expanding Air Shaft Lug Type Spline Steel Inflatable Bearing Core for Rewinder supplier
We are the factory in DongGuan professionally produce transmission parts for machines
Air shaft advantage:
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.
Air expanding shaft Feature
Air shaft Introduction:
The air shaft (air expansion shaft) introducing foreign advanced production equipment and fabrication technology, using imported airbag, shaft head for the high quality steel products with nigrescent process,attrib wattle using excellent aluminum and hard oxide, use convenient and long operate life. When using, match with our company’s professional configuration of the aerate gun filling gas for the nozzle jet, to make the shaft of off-axle appearance uniform expansion, thereby lock nitrogen-treated barrel,when unloading, press on deflated mouth to deflated, then nitrogen-treated barrel can be unloaded.
