AISI 52100 chrome steel balls are widely used in ball bearings and precision mechanical systems, offering high load capacity, excellent wear resistance, and long fatigue life for demanding rolling applications.
Also known as bearing steel balls, GCr15 and 100Cr6 are widely used for precision bearings
and rolling element applications
AISI 52100 chrome steel balls are manufactured from high-carbon chromium bearing steel and are widely used as rolling elements in ball bearings and motion control components.
With a through-hardened microstructure, they ensure stable dimensional accuracy and consistent performance under high contact stress in demanding mechanical systems.
