Constructed in the mid-1930s, the Norris Dam was the first major project for the Tennessee Valley Authority (TVA). Its purpose was to bring economic development to the region and control the flooding that had long plagued the Valley.
TVA worked with Michell Bearings after experiencing numerous thrust bearing failures over the life of one of the two generator units. The failures of the original white metal bearings resulted in excessive downtime and associated loss of revenue.
Michell Bearings was awarded a design contract to investigate the potential problems with the 1930’s design, which had been subject to various attempts over
