Rolling element bearings occupy the sweet spot between cost, size, weight, accuracy, load capacity, friction, durability and accuracy. Modern bearing steels are critically important ultra-high strength structural materials used in a multitude of industrial systems and subject to the highest loading conditions for, in some cases, billions of cycles. They are unique among structural materials because of the localized nature of rolling contact fatigue (RCF) loading, leading to extreme sensitivity of fatigue life to microstructural attributes.
