A hydrodynamic thrust, journal or combined radial and thrust bearing and methods of manufacturing the same. The bearing includes a bearing pad structure that may change shape and move in any direction (six degrees of freedom) to optimize formation of a converging wedge for hydrodynamic operation, equalization of load on the bearing pads in thrust bearings and to adjust for any shaft misalignment. The bearing pad may be formed so as to contact the shaft in the installed state and to deflect under fluid film pressure. The pad is separated from the support member by a support structure which includes one or more beam-like members. The support structure preferably includes a primary support portion, a secondary support portion and a tertiary support portion. The beams allow deflection of the pad by either deflecting or twisting in a torsional mode. The bearing pad support structure may include portions which are fluid dampened. The bearing may be made self lubricating through the provision of a lubricant absorbing and releasing material in the spaces between the bearing pads or within the support structure. The bearings may be made of a wide variety of materials including, plastics, ceramics, powdered metals, composites and metals. The bearings may be manufactured by simple molding using a two-piece camless mold, injection molding, casting, powdered metal die casting, extrusion, electric discharge or laser cutting.
