Ideal for precision spindles, aerospace, medical devices, and high-end industrial equipment, our ceramic bearing balls deliver longer service life, reduced maintenance, and superior operational efficiency.
Precision Grades & Dimensional Data:
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 milímetros (0.0394") a 50.8 milímetros (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 milímetros) 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 CDH) 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 CDH, 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.
Our nylon balls for bearings are engineered for applications where metal balls fall short. These lightweight balls offer exceptional.
Precision Specifications & Manufacturing:We produce our balls to consistent and precise tolerances to ensure reliable performance in bearing assemblies.
Material: Premium Polyamide 66 (PA66), also available in POM (Acetal), PEEK, and UHMW-PE for specific thermal or chemical needs.
Diameter Range: From 3 milímetros (0.118") up to 50 milímetros (1.97") and beyond for custom orders.
Diameter Tolerance: Typically held to ±0.05 mm (±0.002") for standard grades, with tighter tolerances available upon request.
Sphericity & Surface Finish: Precision-molded and machined to ensure excellent roundness and a smooth surface for consistent rolling and reduced friction.
Additives: Available with internal lubricants (e.g., MoS2) or reinforcing fibers to enhance specific properties like wear resistance or stiffness.
