Materials And Performance

Precision anti-friction bearings are most commonly made of chromium steel. This references to a carbon alloy steel containing approximately 1% carbon, 1.5% chromium and lesser amounts of manganese, silicon and in some instances, molybdenum. Modern methods of steel manufacturing combined with up to date heat treatment technology have greatly reduced the non- metallic inclusions. Materials are constantly being checked against Standard ASTM A295 in accordance to the Jernkontoret chart. Quenching temperatures are closely monitored to maintain a martensitic structure with the minimum amount of retained austenite. Stainless steel materials are available for many sizes.
