White etching cracks

Today, bearing failure due to rolling contact fatigue is generally a rare occurrence, and the final achieved service life of rolling bearings is usually well in excess of the calculated rating life. There are instances, […]

Benefits of Hybrid Bearings in Severe Conditions

Hybrid bearings, i.e., bearings with steel rings and bearing grade silicon nitride (Si3N4) rolling elements, have been increasingly used in applications operating in challenging environments [1-4] such as high-speed, oil-free air conditioning and refrigeration compressors, […]
