For three decades research has been performed into the use of nonmetallic and refractory materials as rolling-element materials for use in gas turbine engines. Materials and bearing design methods have continuously improved over the years. Materials such as alumina, silicon carbide, titanium carbide, silicon nitride, and a crystallized glass ceramic have been investigated by NASA in the past. Rolling-element endurance tests and analysis of full-Complement bearings were performed. The paper reviews a wide range of data and analyses to determine where ceramic bearings are most applicable for gas turbines. Special design and mounting requirements are needed to accomodate a full-complement ceramic bearing into turbomachinery applications.
