Introduction to Air Bearings – …
The use of a gas permits a torque orders of magnitude smaller than could be achieved by liquids, but perhaps in practice often of more importance is the fact that a low-torque bearing with an appropriately large operating clearance can be made in a very simple and clean fashion using gas lubrication.

2012-2-24 · In a gas bearing, a film of gas, hereby liberally referred as the lubricant, separates the rotating component (a journal, for example) from the stationary part (a housing or stator). Hydrodynamic
Fluid bearing – Wikipedia
2018-8-24 · Fluid bearings are bearings in which the load is supported by a thin layer of rapidly moving pressurized liquid or gas between the bearing surfaces. Since there is no contact between the moving parts, there is no sliding friction, … hydrostatic and many gas or air bearings, the fluid is pumped in through an orifice or through a porous …
Air bearing – Wikipedia
2018-9-5 · Air bearings (also known as aerostatic or aerodynamic bearings) are bearings that use a thin film of pressurized gas to provide a low friction load-bearing interface between surfaces. The two surfaces do not touch, thus avoiding the traditional bearing-related problems of friction, wear, particulates, and lubricant handling, and offer distinct …
