Bearing wear can occur even when lubricant is present if the lubricant does not maintain adequate separation between contacting surfaces under the actual operating conditions. Contributing factors may include insufficient film thickness, incorrect viscosity, contamination, lubricant degradation or starvation, misalignment, excessive or variable loading, corrosion, sliding, or unsuitable operating temperature. Rolling-contact fatigue may also occur when repeated contact stresses damage the bearing surfaces. The wear pattern should be evaluated together with lubricant condition, load, speed, temperature, alignment, contamination, and bearing geometry to determine which mechanisms are consistent with the observed damage.
Adhesive wear can occur when microscopic asperities on contacting metal surfaces form localized junctions during sliding. Continued motion can shear those junctions and transfer material from one surface to the other. Load, surface finish, material pairing, temperature, sliding conditions, and lubrication can all influence whether adhesive wear develops and how severe it becomes.
Poor lubrication is evaluated by comparing the wear pattern with lubricant condition, viscosity, contamination, operating temperature, load, speed, lubricant supply, and the condition of the contacting surfaces. Scoring, scuffing, overheating, discoloration, or evidence of direct surface interaction may be consistent with inadequate lubricant film separation, but those findings should be distinguished from damage caused by contamination, misalignment, unsuitable materials, or excessive loading. The conclusion should be based on the combined physical and operating evidence rather than on surface appearance alone.
Abrasive wear occurs when a harder surface or loose particle removes material from another surface through cutting, plowing, or scratching. Adhesive wear occurs when contacting surface asperities form local junctions and material is transferred or removed as those junctions shear during motion. Surface features, wear debris, material properties, lubrication conditions, and operating history can help distinguish the two mechanisms.
