Bearing failure chartpdf

This document discusses bearing failures, their causes, and countermeasures. It begins by introducing bearings and how their life is defined. The main causes of bearing failure are identified as heavier loading, inadequate or unsuitable lubrication, careless handling, ineffective sealing, insufficient clearance, and matching bearing life to machine service life. The document then examines different types of bearing damage like wear, indentations, smearing, surface distress, corrosion, and electric current damage. Specific failure modes like flaking, cracks, and cage damage are also outlined. Research on bearing failures in wind turbines is summarized. Overall countermeasures to prevent failures like improving lubrication, mounting, and handling are recommended.Read less
