Silicon Carbide Ceramic Sliding Bearing used for pumps

Silicon Carbide (SiC) sleeves are precision-engineered ceramic components offering exceptional wear resistance, corrosion resistance, high hardness, and thermal stability. Ideal for bearings, seals, and transmission systems in demanding environments across chemical processing, machinery, semiconductor, and energy industries.

• Superior Hardness & Wear Resistance: Mohs hardness of 9.5 (second only to diamond) ensures extended service life
• Excellent Corrosion Resistance: Withstands strong acids, alkalis, and organic solvents
• 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

• Chemical Industry: Pumps, valves, reactor seals
• Machinery: High-speed bearings, precision components
• Semiconductors: Wafer handling fixtures
• New Energy: Photovoltaic and lithium battery production equipment

• Higher temperature resistance with superior mechanical stability
• Minimal clearance changes during thermal cycling
• Reduced thermal deformation minimizes friction-induced binding
• Oil-free operation capability in high-vacuum environments
• Exceptional resistance to acids, alkalis, and salts
• Electrical insulation and anti-static properties
• Non-magnetic and contamination-resistant
