SiC Balls & Marbles (0.5mm–50mm) | Customizable High-Precision Bearing Balls
Our silicon carbide (SiC) balls and marbles offer unmatched hardness, thermal stability, and chemical resistance for extreme-performance applications. Available in diameters from 0.5mm to 50mm, these precision-grade spheres are fully customizable. Ideal for high-speed bearings, semiconductor equipment, aerospace mechanisms, and corrosive fluid systems, SiC balls outperform steel, ceramic, and other materials in wear resistance, temperature tolerance (up to 1950°C), and longevity.
Key Features
✔ Extreme Temperature Resistance – Stable in air (1600°C) and inert gas (1950°C).
✔ Corrosion Proof – Resists acids, alkalis, and plasma erosion.
✔ Lightweight – Density 3.21 g/cm³ (60% lighter than steel), reducing centrifugal forces.
✔ Precision Grades – Grade 5-10 (roundness ≤0.1μm, sphericity ≤0.15μm).
✔ Customizable – Adjustable size (±0.1μm), coatings (DLC), and conductivity (N-doped).
Applications of SiC Ball
1. High-Speed Bearings
- Turbopumps (50,000+ RPM) – SiC’s lightweight and hardness prevent deformation at extreme speeds.
- EV Motors – Electrically insulating variants eliminate arcing risks.
2. Semiconductor & Vacuum Equipment
- EUV Lithography Stages – Particle-free, ultra-smooth surfaces (Ra <0.02μm).
- Wafer Handling Robots – Chemical-resistant for cleanroom environments.
3. Aerospace & Defense
- Satellite Mechanisms – Vacuum-compatible with zero outgassing.
- Jet Engine Components – Withstands 1,500°C exhaust heat.
4. Industrial & Chemical
- Valve Seals – Resists sulfuric acid, seawater, and high-pressure fluids.
- Metering Pumps – Maintains precision flow control for abrasive slurries.
5. Medical Devices
- Surgical Tools – Biocompatible and sterilizable (autoclavable).
- Dental Handpieces – No lubrication needed, reducing contamination.

FAQ
Q1: What’s the difference between SiC and silicon nitride (Si₃N₄) balls?
- SiC: Harder (2800 HV vs. 1500 HV), higher temperature limit (1950°C vs. 1200°C), but slightly more brittle.
- Si₃N₄: Better fracture toughness for high-impact applications.
Q2: What’s the lead time for custom orders?
- Standard sizes (1–10mm): 2–4 weeks.
- Custom sizes/tolerances: 4–6 weeks.
