This document defines, describes and classifies the characteristics of damage occurring in service in 
hydrodynamically lubricated metallic plain bearings due to cavitation erosion, together with possible 
countermeasures. It assists in understanding the various characteristic forms of damage which can occur.
Consideration is restricted to damage which has a well-defined appearance and which can be 
attributed to particular causes with a high degree of certainty. Various appearances are illustrated 
with photographs and diagrams.
