The inflatable shaft is the most widely used retractable reel. For coils of different materials and the weight, width, thickness, winding speed and tension parameters of the coils, the corresponding shaft material thickness and convex key specifications are different. The width of the coil is required to be> 80mm, and the wall thickness of the coil core reaches a certain thickness. For the different requirements of the use of various machinery, the product tube material can be divided into: steel and aluminum alloy materials. The steel surface treatment standard is electroplating hard chromium treatment, and the aluminum alloy surface treatment standard is anodized hardening treatment .

Features: The shaft body of air shaft is made of high-quality steel pipe, and the surface is chrome-plated. It is equipped with high-quality rubber bladder and fast filling and exhausting nozzle. It has good sealing effect, long service life, detachable shaft head and convenient maintenance. After inflation, the unilateral expansion height can reach 1.5mm to 2mm, such as the diameter before expansion is 24.5mm, the diameter after expansion can reach 27.5mm-28mm, special expansion height, separately required.
