Aluminum 74mm Lug Type Air Shaft For 3 Inch Core

Aluminum Material Light Weight Air Expanding Shaft Lug Type 74mm For 3 Inch Core

Summary

CBB brand air shafts are used in the manufacturing processes for fitting into a core onto which materials such as paper, card and plastic film are wound. An Air Shaft is designed so that, on fitting into a core, it can be readily expanded, thereby achieving a quick and firm attachment, it may also be easily deflated to facility easy withdrawal of the shaft after winding of product is complete. Their efficient design makes them ideal for mounting onto bearing housings to enable the winding or unwinding of rolls of stock material with the minimum of equipment down time. The advantage of using an Air Shaft is its ability to grip the core, without damage, whilst providing a positive interface to control the web via motors & brakes. Air Shafts are available as either Key/Lug Type (with bladder down the center) or Board/Leaf Type (bladders on the periphery of the shaft)

Size of Air Expanding Shaft

Standard size

We can customized other sizes of air shaft even if the air shaft is not standard size.

Advantages:

1. Adopting high air press machine to meet interference fitting

We are using a high air press machine for the air shaft, which most of the machine has included it. Air power is more efficient and safe.

2. Adopting hi-precision Aluminum as the shaft body

We adopt hi-precision Aluminum as the shaft body.The thickness of this kind of tube is uniform so when the flat rubber tube 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 special equipment to connect air chamber and shaft head

The connection 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.

4. New Techology

The newest techology for the multi bladder type air shaft, the quality of the air shaft will be stable and good, the life of the air shaft will be long too.

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.

Application

Air shaft is widely used for winding, rewinding and slitting machines. It is widely used in printing, packaging, plastics, paper, glass, pharmaceuticals, electronic battery, textile machine and industry.

Air shaft can used for every kinds of machine which need rewind and unwind.
