High precision balls are within 5/1,000,000′′ round. These are military level specification, used for precision equipment. R-64 hardness, of the highest grade.
52100 High Carbon Chromium Alloy Races:
Vacuum de-gassing process for the purest chromium alloy steel, hardened to R-62, extremely tough and very durable. Polished to a mirror finish for ABEC-5 precision and noiseless movement.
To meet the ABEC-5 standard, bearing design must pass all tests, which include noise testing at high RPM, extremely close tolerances for I.D. and
