It has been demonstrated that bearing rollers made from bearing steel that is carbon-chrome and through hardening have similar or better rolling contact fatigue lifetime than bearing rollers made from any other material. The matching of chemistry only with the specification is not adequate for its use in bearing application. This qualifies to be used for bearing application only when it matches with chemistry and cleanliness both. We make sure to use the steel in which micro-inclusions, micro-cleanliness and micro-structure is maintained and controlled as the fatigue life of bearings depends on it.
