Since the early 1980s, an elegant solution has been the near-frictionless air bearing linear arm which requires no tracking drive mechanism other than the record groove.

With conventional single nozzle air bearings, the compressed air flows through a few relatively large nozzles ( diameter 0.1 0.5 mm ) into the bearing gap.
43.
Typical turbines for this application use an air bearing, where the spinning shaft is suspended in a cushion of flowing compressed air, with virtually no frictional resistance.
44.
The air bearing creates a high-pressure pocket of air for the turbine that acts as a bearing but does not require lubricants such as oil or grease.
45.
Dead volumes refer in particular to chambers and canals existing in conventional air bearings in order to distribute the air and increase the compressed pressure within the gap.

Membrane air dryers are used in pneumatic components, spray painting, laser plenum purge, air bearings, air spindles, medical equipment, air guns and pneumatic brakes for vehicles and trains.

Late Friday afternoon at the same spot, a young man suddenly threw flyers into the air bearing a fervent message against corruption and the growing divisions in society.

In January 1964, David R Snoeyenbos, while working for General Motors Corporation, revised the design of the air caster, and filed a patent for a reversible air bearing support .

The holding force of an air bearing for one solar panel averages 600 N . This force is achieved by an equal distribution of the load on 16 single air bearing elements.
