3 Inch Diameter 75mm Air Expanding Shaft Aluminum Material Key Type Light Weight
CBB brand air shaft, also known as pneumatic reel, is based on the principle of air compression to change the outside diameter of the shaft, andthen closely combined with the reel tube, so as to facilitate the delivery and coiling of the whole reel material, and promote the operation of the production line to be reasonable, simple, accurate and automated. Air shafts are the most widely used take-up and take-up reels
Aluminum material keytype air expanding shaft is especially for high speed machine, the most remarkable feature is the good concentricity, which is important for precsion and high speed material and machine.
Size of Air Expanding Shaft
Standard size of air shaft is useful all over the world for almost all kinds of machines

We can customized other sizes of air shaft even if the air shaft is not standard size.
1. Short inflating time
2. Simple paper tube placement
3. Large bearing weight
4. High economic efficiency
5. Simple maintenance, long use time
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.
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.
Our air shafts are usually packaged by standard wooden box,plywood wooden box and carton,also can be packaged as customer's requirement.
1. Perfect service system and after-sale protection.
2. Quality problems will be solved within 24hours.
3. One-to-one customer service tracking processing.
4. Companies carry out the ERP management, improve enterprise fast response.
5. Quality assurance, one year warranty.
6. Supporting professional matched other equipments.
7. Unique development and design capabilities to meet the needs of special-purpose equipment manufacturing.
