Flexure pivot bearings (Fig. 1) are increasingly found in modern machinery. Modern machining methods make it possible to produce these bearings integral with the bearing shell, which simplifies assembly, installation and dimensional verification during inspection. Lubrication is directed through nozzles between each pad close to the shaft surface. This reduces the effects of hot oil carryover and results in lower bearing operating temperatures and reduced power losses compared to conventional oil-flooded bearing designs. Houston-based Bearings Plus, Inc. uses computer numerical controlled (CNC) wire electrical discharge machining (EDM) manufacturing technology to achieve precise dim
