Functioning Principle

The aerostatic guide and support systems use gas, normally AIR, to lubricate them.

For this reason they are called AIR BEARINGS.

The air is released under pressure inside the part and, using specific more or less complex diffusers (nozzles and micro-grooves), it is distributed among the interacting surfaces. The slightest layer of air (meatus) which is created among them, measures just a few thousandths of a millimetre thick, and it acts as the lubricant with the lowest friction coefficient.
