Description
Self-Lubricating Silicon Carbide Ceramic Sliding Bearing Sleeve
Silicon Carbide (SiC) sleeves are high-performance ceramic components manufactured from SiC. They exhibit exceptional wear resistance, corrosion resistance, high hardness, and thermal stability, making them ideal for bearings, seals, and transmission systems in harsh environments across industries like chemical processing, machinery, semiconductors, and energy.
Key Features
  • Superior Hardness & Wear Resistance: Mohs hardness of 9.5 (second only to diamond), ensuring extended service life
  • Excellent Corrosion Resistance: Resists strong acids, alkalis, and organic solvents, suitable for chemical equipment
  • High-Temperature Stability: Maintains performance up to 1400°C without oxidation or deformation
  • Low Thermal Expansion: High thermal conductivity and thermal shock resistance for rapid temperature cycling
  • Self-Lubricating: Low friction coefficient reduces energy consumption and maintenance
Applications
  • Chemical Industry: Pumps, valves, reactor seals
  • Machinery: High-speed bearings, precision components
  • Semiconductors: Wafer handling fixtures
  • New Energy: Photovoltaic and lithium battery production equipment

Advantages of All-Ceramic Bearings vs. Steel Bearings
  • Higher Temperature Resistance: Maintain superior mechanical stability at elevated temperatures
  • Superior Performance in Thermal Cycling: Minimal clearance changes under temperature fluctuations
  • Enhanced Anti-Seizure & Anti-Jamming Properties: Reduced thermal deformation minimizes friction-induced binding
  • Oil-Free Operation Capability: Self-lubricating properties enable reliable performance in high-vacuum environments
  • Exceptional Corrosion Resistance: Impervious to acids, alkalis, and salts
  • Electrical Insulation & Anti-Static Properties: Non-conductive, eliminating static discharge
  • Non-Magnetic & Contamination-Resistant: Prevents magnetic particle adhesion in sensitive environments
