... contact bearings ROLLING ELEMENT FATIGUE has been recognized since the turn of the century, with fatigue life testing beginning in the early 1900s by rolling bearing manufacturers. Because of the high stresses imposed on bearings, steel with a hard matrix was required. However, the hard matrix, along...
