Measurements of the pressure developed in the load-carrying 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 the distribution of that pressure is investigated using a cup grease under conditions of copious feed. The graphical analysis of the results shows a grease dome similar to that of oil, but flatter and extending over a larger arc.
