Wear and surface fatigue in rolling bearings | Evolution

28/6/2019· In some appliions, rolling bearings can suffer a substantial loss of material (wear) due to lack of lubriion, the presence of abrasive particles, corrosion, oscillating rotation and other causes. Such wear can in turn have a detrimental effect on bearing operation, from the reduction of preload to potentially astrophic effects.
