Frequent and severe failures of spring-loaded thrust bearings can cost million of dollars, both in terms of repairs and generator downtime. Replacing spring-loaded bearings with a self-compensated diaphragm design greatly improved reliability and reduced costs at Alcan Smelters and Chemicals Ltd., Quebec, Canada. The article describes problem analysis, the evaluation of alternative bearing designs, and design and construction of the diaphragms. Analysis of the upper bracket, installation techniques, and operating experience are also described.
