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