What does the bladder of the air inflatable shaft do？

An inflatable shaft is a combined mechanical device consisting of multiple components such as bearings, hydraulic cylinders and air bags. The airbag is one of the important components, and it has a very important role.

The air bag of the core expanding shaft is mainly used to control the pressure and force of the inflation shaft to ensure its normal operation. First of all, the air bag can be used as a medium for pressure transmission, and by compressing the internal air, the air expansion shaft generates a certain pressure and forming force. At the same time, the air pressure of the air bag can be adjusted by the air supply system, so that the pressure and forming force of the air expansion shaft can be controlled and adjusted.The air expansion shaft airbag discharge does not need to remove the entire shaft. After direct deflation, the material can be removed, because its width is not large, so the natural operation is more convenient. This is also the choice of many machines with light weight and small width.

The air expansion shaft bladder has a balanced force pressure, so that it can evenly distribute the pressure, play a shock absorption and cushioning role, and protect the bearings and other sensitive parts of the air expansion shaft. It generally only takes about 2 seconds to complete the inflation and deflation process, and the steps of operating and placing the reel are very simple and practical, and are not dangerous.

 The multi bladder type /lug type air expansion shaft of PRE use Imported transparent flat airbag  have long service life and low maintenance rate .
