The statistical framework that answers 'how long will this bearing last?' A step-by-step look at basic rating life L10, the load-life exponent, and the modified rating life (ISO 281) that accounts for lubrication and cleanliness.
Over 90% of bearing damage stems not from the bearing itself but from external causes. Following the ISO 15243 classification, learn to read the marks of fatigue, wear, corrosion, electrical erosion, plastic deformation, and cracking — and their root causes.
Lubrication is not merely 'adding oil.' The ratio of film thickness to surface roughness (λ) governs friction and life. Understanding bearing lubrication through the Stribeck curve and EHL theory.
How rolling-element bearings cut friction, how ball and roller designs differ, and how radial and axial loads travel through the rolling elements — explained from a design perspective.
