Compressed air enters through an air inlet, inflates the diaphragm, and balances the load.
(The internal pressure is the value of the load divided by area of the diaphragm.)
The air stored up in the diaphragm then leaks through a small hole and escapes through the space between the diaphragm and the floor. As the air escapes, it forms an extremely thin film that functions as a lubricant.
This is the principle behind the air transportation device known as an air bearing.
Freedom of movement
The object can be moved and rotated freely around the floor as movement is not constrained in any direction.
Capacity exceeding 1,000 tons
All manner of heavy objects (exceeding 1,000 tons) can be transported by being floated on air at pressures of 0.15 to 0.35 MPa.
Easy setup
Because pressure supports the heavy object being transported, simple frames can be used for ease of setup.
Maintenance-free design
Air bearings require no maintenance and have absolutely no parts — such as sleeves — that require oiling.
No floor damage
There's no need to worry about floor wear and tear, as objects are lifted on a film of air before being transported.
Thin-profile design
Air bearings require very little vertical space as they are quite thin. (Even a 300 kN unit requires only about 30 mm.) As long as a small amount of space is available, an air bearing can be positioned beneath existing equipment and made available for immediate use simply by connecting an air source.
Clean design
Air bearings are clean, dust-proof, noise-free, and vibration-free, and they do not pollute the environment. What’s more, the air around the device remains mostly undisturbed and the floor is not damaged.
