Premium Full Ceramic Bearings 6204 – Unmatched Durability & Performance
Factory-direct high-grade zirconia (ZrO2) or silicon nitride (Si3N4) ceramic construction ensures extreme corrosion resistance, non-magnetic properties, and thermal stability up to 800°C. Precision-engineered deep groove raceway minimizes friction for ultra-smooth rotation (ABEC-5+ tolerance). Ideal for high-speed applications: medical/dental equipment, food processing machinery, semiconductor tools, and electric vehicles where lubrication-free, contamination-proof operation is critical. Optional shields (ZZ/2Z) or seals (RS/2RS) for dust/moisture protection. Wholesale advantage: Bulk pricing for industrial buyers with guaranteed lowest global rates. Custom configurations (cage material, hybrid ceramic-steel variants) available for OEM partnerships.
