ABSTRACT:
A fluid film bearing suitable for use with either liquid or gaseous fluid and capable of far greater lift because of the larger usable lifting surface. The larger lifting surface is achieved in that the bearing assumes a square, rectangular, or race track configuration, a configuration which is more easily adapted for use in combinations of multiple bearings for large lift capacity and further may more closely approximate the shape of an object to be lifted or moved. An integral high tensile strength, flexible membrane gives the fluid bearing sufficient strength to withstand internal pressures over elongated, non-circular peripheral portions and also gives the bearing a far greater ability to flex and conform to an uneven or undulated surface thereby enabling the bearing to comply with a surface of far less uniformity without the loss of support than was heretofore possible. The utilization of a bifurcated membrane while adding strength increases the ability to comply to a greater extent as well as increasing the jacking ability.
