ABSTRACT:
The required pumping power for hydrostatic bearings is reduced with bearings having at least two lubricating areas bounded with a narrow raised perimeter of lower clearance. The lubricant is supplied under pressure and is retained with an area which is large enough to provide a low friction thick film of lubricant while the clearance at the narrow, raised perimeter is small enough to provide satisfactory control of lubricant loss rates. In particular embodiments, the raised perimeter is provided by sealing assembly mounted on one side of the sliding surfaces.
