Abstract : A program is described which had as its objective the attainment of several cycles of operation including portions at 700 F and the simulated pressure of 80,000 feet. Major attention was given to grease packed bearing systems. The most successful performance was obtained with both an auxiliary grease supply and periodic injection of base fluid to the grease. A circulating grease system is described which shows promise for improved elevated temperature operation. Some atten ion was given to the use of an oil lubricated system. This was not as promising as the grease system. Dry Operation is discussed, and preliminary data are presented. (A UTHOR)
