The Material of Sealed spherical roller bearing

The Material of Sealed spherical roller bearing

 

Sealed spherical roller bearing adopt the most widely used Quenching chrome steel,the carbon  chromium steel conform with ISO0683-17:1999,contain approximately 1% carbon and 1.5%  chrome.because of sealed spherical roller bearing service life is increasing,carbon chromium 

steel is still the longest history of useful and most comprehensive research steel,this chrome steel are achieve the best balance both in the manufacture and applications,the chrome steel used in manufacture sealed spherical roller bearing are usually under process of heat treatment of martensite or bainite.hardness range between 58-65HRC.

 

Along with the development of steelmaking technology,the purity of steel is achieve higher standard.its play very important role in the quality and consistency of XRB chrome steel,XRB (China Bearing manufacturer)sealed spherical roller bearing adopted high quality chrome steel with very few Non metallic inclusion and oxygen content.
