G5-G1000 Precise bearing ball aisi 52100 chrome steel ball

AISI 52100 is a high-carbon alloy steel and contains another key element of chromium that featured with excellent mechanical properties, including high hardness, strength, and wear resistance. The chromium steel ball’s properties are also achieved through heat treatment, including quenching and tempering. The hardness of AISI 52100 chrome steel ball ranges from 60 to 66 HRC (Rockwell C Scale). 

The precision AISI 52100 chrome steel balls are know as bearing steel balls that used in automotive parts, recirculating ball screws, high precision spindles & gears, ball transfer unit, high speed and low noise bearings and mining machinery.
