High Purity Silicon Nitride Ceramic Balls for Precision Engineering
Ultra-smooth polished surface with sub-micron roughness ensures minimal friction and wear. Made from 99.9% pure Si3N4 for exceptional thermal stability and corrosion resistance. Ideal for high-speed bearings, precision valves, and linear sliders in aerospace, medical, and industrial automation. Superior hardness (HV 1500+) outperforms steel in extreme conditions. Exact spherical tolerance (±0.0001") guarantees perfect rolling motion. Non-magnetic and electrically insulating for sensitive applications. Direct factory pricing—bulk orders available for global distributors. Stocked in multiple sizes (1mm-50mm) for immediate shipment.
