Fatigue life testing was performed on tapered roller bearings using several fire resistant hydraulic fluids. The test fluids included an ester-oil blend, synthetic esters, invert emulsions and water glycols. For comparison, tests were also run in a reference petroleum oil and a petroleum type antiwear hydraulic oil of similar viscosities. Test results show that the relative bearing fatigue life compared to the reference oil ranged from 100+ percent for the ester oil blend to 14 to 24 percent for the water glycol.
