Product Introduction
3x10x4mm 693CE 693 Full Ceramic Bearings (ZrO₂/Si₃N₄) | Self-Lubricating & Corrosion-Proof

Core Features & Benefits:

 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 machineryI'm sorry, but there is no text provided for translation. Please provide the text you would like me to translate.


 Extreme Temperature Stability

No thermal expansion at 150°C – maintains precision in oven conveyors and autoclave systemsIt seems that there is no text provided for translation. Please provide the text you would like me to translate.


 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).


Industry Applications:

 
Sector Use Cases Recommended Type
Semiconductor Wafer transfer robots, CVD machines ZrO₂ + Si₃N₄ balls
Medical Surgical robot joints, MRI scanners Double-sealed ZrO₂
Chemical Processing Acid pumps, mixer shafts PEEK cage + ZrO₂
Photovoltaic Solar cell etching lines Full ceramic PTFE sealed
Food & Pharma Sterilization tunnels, filling machines FDA-grade PTFE cages
