Advantages

Advantages of air shaft

1. Adoping high power press machine to realize interference fit

We are using a high power press machine which can produce 80T thrust to realize all the combination of spindle head and steel tube for the air shafts. Light type air shaft is with 0.03mm interference fit.Heavy type air shaft is with 0.06mm interference fit.While many factories knock it in with a big hammer,no quality and accuracy.

  

 

2. Adopting  hi-precision cold-drawn steel tube as the shaft body

We adopt  hi-precision cold-drawn steel tube as the shaft body.The thickness of this kind of tube is uniform so when the rubber balloon inside is inflated ,all key strips will stick out at same height .And it will  greatly weaken centrifugal force of the whole air shaft when it is rotating and will keep a dynamic balance. 


 

3. Adopting whole long key bar and pagoda springs for key type air shafts

We use the whole long key bar to form a good protective ring around the air shaft air chamber ,and we adopt the pagoda springs which can bear 300000 compression spring .The key bar is made of aluminum alloy. It is light in weight and suitable for ordinary tubes such as paper tubes.

 

4. Adopting special equipment to connect air chamber and shaft head

The connection mode between the air chamber and the shaft head is very important process,our company are using special equipment to realize it.Outside is buckled by siderosphere directly which can realize good sealing performance and stability. Many air shafts produced by other suppliers , both ends are fastened by iron wire,this is easy to leak and is with unstable sealing performance.

 

5. Quality control

We have the quality control system during the whole production from the very beginning to the end and our principle is to make sure each shaft  is qualified.

 

6.Packaging

Our air shafts are usually packaged by standard wooden box,plywood wooden box and carton,also can be packaged as customer's requirement.
