6 Inch Multi Bladder Type Air Expanding Shaft

Air shaft is a special shaft for winding and unwinding. 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 shafts

5.Differential Air Shafts

6.Slitter Knife Shafts

6 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.
