Also known as bearing steel balls, GCr15 and 100Cr6
AISI 52100 chrome steel balls are the most widely used rolling elements in ball bearings and precision mechanical applications. Through-hardened to 60–66 HRC, they offer excellent load capacity, wear resistance and fatigue life for high-performance bearing systems.
To Share:
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, these balls provide excellent resistance to wear and fatigue under high contact stress. They are suitable for applications requiring stable dimensional accuracy, low vibration and reliable long-term performance in mechanical systems.
