Air Shaft Expandable Leaf Type Air Expanding Shaft

Product DescriptionDescriptionThe contraction part of the plate type inflatable shaft is the plate, usually the expansion height can reach 4mm to 5mm, for example, the diameter before contraction is 74mm to 75mm, and the diameter after contraction can reach 78mm to 79m. The special contraction height is separately required and determined by the customer. The 3 inch plate type inflatable shaft usually uses a coil with an inner diameter of 76mm. The plate type inflatable shaft shrinks from the entire plate, the fulcrums are evenly dispersed, and the force is average. It can be used for machinery with higher winding precision or winding Light items.Expanding method:Air Expanding TypeExpanding Element Material:Aluminum LeafOuter Diameter:74mm-74.5mm(can be customized as per customers'demands or drawings)Length:Customized based on drawingMaterial of Shaft Body:Steel,Aluminum alloyMaterial of Shaft End:SteelColor:Silver or TawnyInner Diameter of Applicable Tube74mm-74.5mm(Customers need to inform their CORE ID exactly)Features: The expansion part are leaves, usually the height of the expansion can reach 4mm to 5mm, such as the diameter before expansion is 49mm, the diameter after expansion can reach 53mm to 54mm, special expansion height can be customized by customers,2-inch leaf type air shaft is with a coiled tube inner diameter of 50mm. The plate type air expansion shaft expands from the whole plate, the fulcrum is evenly distributed, and the force is uniform. It can be applied to machines with high precision of winding or lighter articles, such as electronic materials,battery materials,foaming, cotton, plush,paper towels,non-woven, etc., mainly based on actual needs.Under what conditions do you need to use a slatted air shaft?a. When the product needs to be wound in strips, and the width of a single wound product is narrow;b. When the product requires a higher true circle;c. When the roll paper core or other raw material roll used in the product has a thin wall or is of poor quality and is easily deformed.Product Parameters Technique parameter ModelInner Diameter of Paper TubeShaft Diameter Before ExpandingShaft Diameter After Expanding1″ ShaftΦ25.4mmΦ24.5mmΦ27.5mm-Φ28mm1.5″ ShaftΦ38mmΦ37mmΦ41mm2″ ShaftΦ50mmΦ49mmΦ53mm3″ ShaftΦ76.2mmΦ74mm-Φ74.5mmΦ82mm4″ ShaftΦ102mmΦ100mmΦ108mm6″ ShaftΦ152.4mmΦ150mmΦ158mm8″ ShaftΦ203.2mmΦ200mmΦ210mm10″ ShaftΦ254mmΦ250mmΦ260mm12″ ShaftΦ304.8mmΦ300mmΦ312mmNote: According to customers' special size requirements, production design can be carried out to meet your needs.The purpose of the key strip type inflatable shaft: the product is used in the slitting, printing, rewinding, coating, laminating, bag making, paper making, electronic battery and other related machinery or other related center drive winding Used in conjunction with the material sending machinery.Application Packaging & Shipping   Order Details Item Name3inch Leaf Type Air Expanding ShaftMOQ(Minimum Order Quantity)1PcLead time13-15 days after receiving the depositCalculated Weight8kg/Meter(Aluminum Body),14kg/Meter(Steel Body),PackageCarton/Wooden BoxPrice TermEXW,FOB, CIF, etcPayment termTT,L/C,Western UnionCountry of OriginChina/* January 22, 2024 19:08:37 */!function(){function s(e,r){var a,o={};try{e&&e.split(",").forEach(function(e,t){e&&(a=e.match(/(.*?):(.*)$/))&&1
