Bearing steel is very high quality steel and is typically chromed. The material is quenched and then tempered at around 150°C. Bearing steel is characterised by its:
Both high and low carbon steels are used for bearings and both types have their own particular uses based on their properties. Many of these steels are covered by SAE-AISI designs and are generally very hard, durable and resistant to compression. These are all characteristics which are make this material ideal for the production of ball bearings, rollers and roller bearing cases.
