Grease systems capable of operating in loaded bearings over the temperature range of -65 to 900 F were investigated. Current work was done on a 0 to 600 F grease system under 5 lb. radial and 5 lb. axial load and 50 lb. radial and 25 lb. axial load. Some tests were carried out at 650 and 700 F under light load. Greases made by blending F-6-7024 Silicone Fluid and one of several polyphenyl polysiloxanes and thickening with Ammeline have given the longest 600 F, high load bearing tests to date. Bearing tests on a series of these greases range from 150 to 220 hours. Ammeline is the only thickener that gave these long bearing tests with these blends.
