DEFINITION
Classification: 29/898.02
Fluid bearing:
(under subclass 898) Process of manufacturing a bearing wherein liquid or gas under pressure is used to support a component in whole or in part during relative movement of the manufactured bearing.
(1) Note. Fluid (i.e., liquid, or gas) support and lubrication both involve interposing a fluid between relatively moving members. In general, the difference between them is that lubrication merely minimizes contact between the members whereas fluid support eliminates it altogether via a thicker layer of fluid. Almost all gas, hydrodynamic, or hydrostatic bearings involve fluid support.
