This final report for a 3-year contract contains the results of several projects conducted on the program. The first project was a long-term repeatability study on the four-ball wear testers. The work was done to assure that the two test machines were constant in performance. The data confirm that the machine performance was as constant as could be statistically expected, both from machine to machine and for each machine as a function of time. The second project was to conduct four-ball wear tests on various oils and greases to determine the ability of the lubricants to prevent wear at various conditions of speed, load, and temperature. Data from 1,320 tests on 246 materials are reported. The third and fourth projects were to determine performance lives of various greases on the Pope spindles and Navy spindle. Equipment descriptions and test results are included. The fifth project was grease testing in the Sikorsky rigs. This rig is described and test results presented. The Sikorsky rig test procedures do not appear to be well suited for research testing. The last project discussed was the long-term testing of lubricant compact materials in ball bearings.
