Surface damage created by debris significantly reduces the life of rolling element bearings. The metallurgical structure of a bearing raceway can be modified to optimize strength and damage tolerance. The correct balance between raceway strength and damage tolerance can significantly improve bearing life in contaminated environments. Two test procedures exist for measuring the damage tolerance of steels. Both test procedures produce comparable results, which can be correlated using baseline data. Damage tolerant steel produces a significant life improvement in large tapered roller bearings.
