1 Inch Multi Bladder Type Air Expanding Shaft
1inch air shafts are used in the producing processes for fitting into a core onto which materials such as fabric, nonwoven and plastics are winded. An Expanding Shaft is designed so that, on fitting into a core, it can be easily expanded, thereby achieving a quick and firm attachment, it may also be rapidly deflated to facility easy withdrawal of the shaft after winding of product is complete.

Specially recommended surface multi bladder inflation shaft:
The traditional air shaft has only a single central airbag, and the expansion force applied to each key is not uniform, and the concentricity is difficult to ensure, and the maintenance of the bladder is difficult after the damage, which is very time consuming.

Product features
1: The inflation operation time is short. It takes only 3 seconds to separate and place the inflation shaft and the paper tube to complete inflation and deflation, and it does not need to separate any parts at the end of the shaft to tightly engage with the paper tube.
2: The paper tube is placed simply: with the action of inflation and deflation, it can move and fix any position of the paper tube on the shaft surface.
3: Large bearing capacity: the size of the shaft diameter can be determined according to the actual needs of customers, and high strength steel can be used to increase the bearing capacity.
4: High economic efficiency: the shaft is designed for special functions, which can be used for all kinds of paper tubes that are thick, thin, wide and narrow.
5: Simple maintenance and long service life: the air expansion shaft is a single part, and each part in its structure has a fixed specification, which can be interchanged for easy maintenance.
