High-Performance Full Si3N4 Black 206 Deep Groove Ball Bearing
Ultra-durable silicon nitride (Si3N4) ceramic balls ensure superior corrosion resistance, extreme temperature tolerance (-60°C to 800°C), and 3x longer lifespan than steel bearings. Precision-engineered hybrid ceramic design reduces friction by 40% for high-speed applications (up to 30,000 RPM). Perfect for industrial machinery, electric motors, automotive systems, and aerospace components requiring minimal lubrication and zero electrical conductivity. Mirror-polished raceways and PEEK cages eliminate vibration in sensitive equipment.
