Micropitting occurs in gears and rolling-element bearings thatoperate in the mixed or micro EHL lubrication regime. It manifestsin many different ways depending on the loads, speeds, rolling andsliding velocities, macrogeometry, surface topography, edgeeffects, metallurgy, and lubricant properties. The failure analystmust discern whether the micropitting is a primary failure mode ora secondary failure that occurs because of prior damage.Understanding the morphology of micropitting is the key todetermining the primary failure mode and root cause of failure.Several examples of micropitting in gears and rolling-elementbearings are presented to illustrate the morphological variationthat can occur in practice.
