Ultra-Precision Si3N4 Ceramic Bearing for Demanding Applications
Engineered with non-magnetic silicon nitride (Si3N4) for extreme environments, this full-ceramic bearing delivers unmatched corrosion resistance and electrical insulation. The single-row design (10x30x9 mm) ensures smooth operation under high speeds (up to 80,000 RPM) and temperatures exceeding 800°C. Ideal for aerospace, medical equipment, and high-vacuum industrial tools, its polished raceways minimize friction for silent, maintenance-free performance. The HXHV-grade ceramic balls outperform steel in longevity, reducing downtime in CNC spindles and semiconductor machinery.
