Silicon nitride ceramic rotary bearings

Features

1. High Hardness and Wear Resistance: Vickers hardness ≥1500HV, 2-3 times that of bearing steel, significantly reducing wear.
2. Low Density: Density is only 3.20 g/cm³ (approximately 40% of steel), reducing centrifugal force during high-speed rotation.
3. High Temperature Resistance: Maintains stable performance in high-temperature environments up to 800℃, with some products resistant to temperatures up to 1200℃.
4. Corrosion Resistance: Strong resistance to corrosive media such as acids, alkalis, and salts.
5. Electrical Insulation: Suitable for electrical equipment to prevent electrolytic corrosion.
6. Self-Lubricating: Low friction coefficient of 0.1-0.2, allowing use in environments without lubricating media.
7. Long Lifespan: Service life is 3-5 times that of all-steel bearings.
