Expansion Shaft
The principles and characteristics of expansion shaft.
1 Pneumatic reel and expansion shaft, based on the principle of air compression, the diameter of the shaft changes, and then closely with the volume control, facilitate the take-up the entire volume to send materials to promote the production line operation of the reasonable, simple, accuracy and Automation.  
2When the air into the internal expansion, the axis of the main parts were expanded within the extrusion, changing the diameter of the main axis increased, prompting the exact volumes of full width of the main body fixed to the shaft.  
3When the internal air is released, the expansion of extrusion parts retracted, the axis will be taken out can be very convenient. Strip-type air shafts  
4Axis of the main high-stress steel or aluminum alloy material, the internal expansion of the body made of imported synthetic rubber as a special form. 
5The main used by the tissue machine, rewinder machine and converting machine.
6We can offer ever size expasion shaft for you if you need .
7As follow we will introduction the expansion shaft used by the tissue machine.the main size have 3inch,6 inch,*0inch.,*4inch……
