ABSTRACT:
A self-compensating linear fluidstatic or hydrostatic bearing and method in which preferably circular annular pressurized-fluid-receiving grooves provided in the opposed carriage bearing surfaces regulate the fluid fed to longitudinal recess pockets formed in the opposing bearing surfaces to provide a thin film or layer of pressurized fluid in the gaps between a bearing rail and the opposing bearing surfaces; the regulation establishing differential pressures in the opposing bearing surface pockets to compensate for loads applied to opposite sides of the bearing.
