- 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.

We supply standard grades from G5 to G100, with higher grades (e.g., G5, G10) offering the tightest tolerances for critical, high-speed applications. Sizes are available in a wide range, from miniature sizes of 0.5mm (0.0197") to larger diameters of 50.8mm (2.0") and beyond, depending on the material.
Materials & Key Properties:
• Chrome Steel : The industry standard, offering an excellent balance of hardness (60-67 HRC) and load capacity. Ideal for most general industrial and automotive applications.
• Stainless Steel (440C, 316): Provides superior corrosion resistance. Grade 440C is martensitic and can be hardened to 58-60 HRC, suitable for food, marine, and chemical environments. Grade 316 (austenitic) offers maximum corrosion resistance for highly aggressive media.
• Ceramic (ZrO2/Si3N4): These advanced bearing balls are lightweight (60% lighter than steel), electrically insulating, and highly resistant to wear, corrosion, and thermal expansion. They operate effectively in high-speed, high-temperature, and chemically hostile environments where metal fails.
