Abstract
Phosphate ester, phosphate ester-base, and water-glycol-base combustion-resistant fluids and a petroleum oil were investigated to determine the relative effects of the fluids, used as flood lubricants, on the life of angular-contact ball bearings. Bearing life was lower in the combustion-resistant fluids than in oil, ranging from 58 per cent of the life in oil for the phosphate ester, to 6 per cent for the water-base fluid. Fatigue failures of the bearing races were prevalent for all fluids and additional investigations are required to determine the causes of the wide variation in bearing life in the various fluids.
