Mechanical Properties
Bearing steel balls are uniformly hardened and tempered throughout their entire diameter to achieve maximum strength

 and quality. 

Ball hardness is controlled within the 60-67 HRC 

range as measured on parallel flat surfaces. Custom heat treating is available for special hardness and dimensional stability

 requirements.
