✅ Zero Lubrication Required
Self-lubricating ZrO₂/Si₃N₄ eliminates oil/grease – ideal for semiconductor cleanrooms and high-vacuum environments (e.g., space tech).
✅ 5X Longer Lifespan in Wet/Chemical Environments
Resists acids/alkalis that corrode steel bearings – proven in electroplating lines and textile dyeing machinery.
✅ Extreme Temperature Stability
No thermal expansion at 150°C – maintains precision in oven conveyors and autoclave systems.
✅ Electrically Insulating & Non-Magnetic
Relative permeability <1.001 – prevents magnetic particle adhesion. Essential for:
MRI machines
Semiconductor wafer handlers
Degaussing equipment
✅ Silent Operation & Low Friction
Surface roughness Ra ≤0.1μm reduces noise by 15 dB vs. steel bearings (tested per ISO 140-3).
