- Grades: G5, G10, G16, G25, G40, G100 (per ISO 3290). G5 represents the highest commercial grade with near-perfect sphericity and minimal diameter variation.
- Diameter Range: From 1 mm (0.0394") to 50.8 mm (2.0"), catering to miniature instruments and large industrial machinery.
- Diameter Tolerance: As tight as ±0.00008" (±0.002 mm) for G5 grade.
- Sphericity: As low as 0.00008" (0.002 mm) for the highest grades, ensuring smooth, quiet rolling motion.
- Surface Roughness: Achieves a mirror-like finish with Ra ≤ 0.02 μm, minimizing friction and heat buildup.
