52100 Bearing Steel Round Bar is a high-carbon, high-chromium through-hardening steel manufactured to ASTM A295 / SAE J403 standards. It delivers excellent surface hardness, superior wear resistance and high rolling contact fatigue strength — making it the industry standard for rolling-element bearing components including balls, rollers, races and bearing rings. Supplied in hot-rolled, forged, peeled or ground finish with full mill test certification.

100Cr6 Bearing Steel Tube is a high-carbon chromium through-hardening seamless steel tube manufactured to EN ISO 683-17 and DIN 17230 standards. It is the European benchmark grade for rolling-element bearing components, delivering excellent surface hardness, superior wear resistance and high rolling contact fatigue strength after quenching and low-temperature tempering. Supplied in spheroidized annealed condition for machinability, with full mill test certification.
