James Dale McMillian, Dale to his friends and peers, is a mechanical engineer with several passions, the first for energy and aerospace. The second is the role of the shaft and bearing assembly for these sciencs. Yes, they are closely related, however, the shaft and bearing assembly go far beyond energy and aerospace. There are four sciences that oversee the future of exacting performances for products of these industries. They are Metallurgy, Metrology, Tribology, and Mechanurgy. Dale has circled the globe working with hands-on crews and engineering groups for energy, aerospace, and precision accuracy for steel, printing, and paper mill rolls applications. Participating at oil and gas drilling sites to the in-plant manufacturing of indexable wing aircraft has provided him with an array of unique and beneficial experiences. The opportunity to work close to turbine and generator manufacturers has added to his knowledge of energy-producing products. Bearing and shaft design plays a major role in these industries. He has studied with bearing manufacturers in Germany, England, Italy, and Mobile USA. As a result of these studies, He is consulted frequently on suspicious bearing failures due to possible contaminated lubrication. Dale has an in-depth study of metallurgy. These are instrumental when evaluating shaft and bearing failures. The bearing is not always the culprit. Lubrications subject to accelerated failure, errors in shaft design, and extreme subjection to mechanical forces can also be the cause of failure. Dale is currently active as a manufacturing consultant for the work holding and critical application industries.
