The contract for investigation of ceramic materials in rolling contact bearings, was carried out with high strength silicon nitride, silicon carbide and aluminum oxide. Screening rolling contact fatigue testing on silicon nitride with conventional lubricants showed excellent life, greater than M50 steel, at comparable load. The friction and wear properties were determined for silicon nitride, silicon carbide and steel. The coefficient of friction and wear rates are nearly the same for steel-steel and steel-silicon nitride combinations.
