1.1 This specification covers medium carbon bearing quality steel to be used in the manufacture of anti-friction bearings.

1.2 Supplementary requirements of an optional nature are provided and when desired shall be so stated in the order.

1.3 The values stated in inch-pound units are to be regarded as the standard.


This specification covers the standard specification for medium carbon bearing quality steel to be used in the manufacture of anti-friction bearings. The bearings shall conform to the required chemical composition for carbon, phosphorus, manganese, sulfur, silicon, chromium, molybdenum, vanadium, copper, oxygen and aluminum. Requirement for dimensional tolerances of hot-rolled or hot-rolled and annealed bars, in straight lengths or coils, and cold-finished bars and larger in diameter furnished shall conform to the specified size, shape and tolerances. The grain size of the material shall conform to the required size, otherwise it shall be normalized and retested. Decarburization and surface imperfection shall not exceed the limit in the specified values. Material may be ordered as hot rolled or thermally treated. No hardness limits shall apply for as-hot-rolled materials.
