Air bearing - Wikipedia

In many cases engineers can create air bearings that approach the theoretical limit of performance. Rather than a few large nozzles, aerostatic bearings with lots of micro nozzles avoid dynamically disadvantageous dead volumes. Dead volumes refer to all cavities in which gas cannot be compressed during decrease of the.
