A series of powdered and gaseous type lubricant rolling and sliding characteristic studies are described. Lubricant materials evolved from these studies were evaluated in 20 mm angular contact bearings of titanium carbide cermets and cobaltbase alloys over the range from room temperature to 1200 F. The three most successful gaseous entrained lubricants--molybdenum disulfide in a nitrogen environment, graphite plus cadmium oxide mixture in an air environment, and molybdenum disulfide plus metal-free phthalocyanine mixture in a nitrogen atmosphere--have shown promise in ball bearings operating at speeds to 30,000 rpm and thrust loads of 100 lb over the range from room temperature to 1200 F for periods to 10 hr.
