Film Pressure Distribution in Grease-Lubricated Journal Bearings. 1-GUNTHER COHN ~AND JESS W. ORES.3 Measurements of the pressure developed in the loadcarrying film of a grease-lubricated journal bearing show that grease can operate under hydrodynamic conditions. In a testing fixture, constructed for the purpose, the magnitude and distribution of that pressure is investigated using a No. 2 grade ball-and roller-bearing grease under conditions of copious feed. Fundamentally, the fixture consists of a test bearing and a drill press, the arborof which drives the journal. The latter is movable in such a way that a gage connected to a single tap hole can measure the pressure at any point in the film. The lubricant is fed into the bearing through an axial channel and is separated from the gage fluid by a diaphragm.
