Si3N4 bearing vs ZrO2 bearing
| Feature | Si₃N₄ Ceramic Bearings | ZrO₂ Ceramic Bearings |
|---|
| Material | Silicon Nitride (Si₃N₄) | Zirconia (ZrO₂) |
| Strength & Hardness | Very high, superior toughness | High, but less tough than Si₃N₄ |
| Weight | ~60% lighter than steel | ~40% lighter than steel |
| Temperature Resistance | Excellent for high-temperature applications | Good, but lower than Si₃N₄ |
| Thermal Conductivity | Higher → better heat dissipation | Lower → more insulating |
| Wear Resistance | Superior, long lifespan | Good, but slightly lower |
| Corrosion Resistance | Very good | Excellent (better against harsh chemicals) |
| Cost | Higher | More economical |
| Best for | High-speed, high-load, aerospace, precision use | Food, medical, chemical, and corrosion-heavy use |
