ABSTRACT:
A foil member is stretched over a body of pressurizing material so as to be caused to balloon outwardly toward a rotating shaft. A fluid (e.g., air) film bearing is formed between the foil and shaft. The pressurizing material for the foil may be incompressible, but capable of plastic flow (e.g., water). Consequently, the foil is substantially stiff and unyielding to movement of the shaft toward the foil, but is locally yielding as to particles of foreign material that may get into the air film zone between foil and shaft or to misalignment of the shaft, and elastically recovers its original shape when the particle is gone, or the misalignment is corrected, having meanwhile suffered no damage.
