The shaft is designed by the key/leaf/lug on the surface, which will be expanded when the high-pressure gas filled enter into the shaft inside. The customer just aired the shaft through the air valve and when user want to lock the coils or web, and just push the core of the air valve to deflate, the keys will revert to its original appearance, then web can be dismantled simply.Expanding shafts are widely used for winding, rewinding slitting ,printing, packaging, plastics, paper, glass, pharmaceuticals, electronic battery, textile machines or industries.6inch Core shafts and expanding shafts are used to handle winding rolls in the processing of web-fed materials. They are worked with equipment such as continuous-process printing machines. Mandrels and air shafts are similar to the axles on an auto. They apply as the connection between the motor that drives the reel-winding application and the roll itself.There are many different models of air shafts and core shafts,including:1.Standard Air Shafts(Lug type or Leaf Type)2.Internal Bladder Air Shafts(Single Bladder Type)3.External Bladder Air Shafts(Multi Bladder type)4.Light Weight and Aluminum extrusion shafts5.Differential Air Shafts6.Slitter Knife Shafts6 inch pneumatic shaft features:(a). Lightweight structure: Reduce the risk of operator injury, light weight (aluminum alloy).(b). High roundness and less jitter: The circumference is eight equal parts and the force is uniform, which can replace the traditional leaf air shaft.(c). Simple maintenance and easy assembly and disassembly:Upper and lower two-piece press key design: Bladder replacement can be easily done without disassembling the entire shaft.(d). imported transparent flat airbag, long service life and low maintenance rate.(e). Internationalization of quality and localization of prices.Technique parameterModelInner 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" ShaftΦ304.8mmΦ300mmΦ312mm4:ApplicationUsing of air shaft is extensive,as long as there is the mechanical part of the working group winding , unwinding , etc. , you will see it,such as printing machine,coating machine,leather machine,embossing machine,slitting machine,cutting rewinding machine,paper tube machine,bag making machine, laminating machine , laminating machine , blown film machine, paper machine , non-woven machines, fabric inspection machine, etc.will be used in air shaft .ApllicationReal Delivery PicturesIf you need more information or contact us early, you can check: www.pre-webguidesystem.com
