Tapered roller bearings, damaged in field applications or laboratory tests have been subjected to a systematic analysis of such damage to prevent its recurrence in the field or to gain knowledge of its control in the laboratory. A method of analysis is described which has been developed for examining such bearing damage. The essential steps of the analysis are described with emphasis on the visual classification and metallographic examination of the damage. Bearing damage is classified in two major categories, that resulting from contact fatigue, and that due to other mechanisms. Damage which is related to material, surface finish, geometry, local asperities (grooves and bruises), the lubricant viscosity is usually due to contact fatigue. Damage due to other mechanisms is that which results from obvious mechanical, chemical, or electrical factors in the application which either change bearing geometry or eventually cause contact fatigue.
