Product Description
Silicon Carbide Ceramic Sliding Bearing Sleeve
High-Performance Ceramic Components for Extreme Environments
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 applications across chemical processing, machinery, semiconductor, and energy industries.
Key Features
- 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
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
Technical Properties
| Property | Value |
|---|---|
| Max Temperature | up to 1650℃ |
| Density | 3.15-3.18 g/cm³ |
| Thermal Expansion | 4.0 (10⁻⁶/℃) |
| Thermal Conductivity | 120 W/m°K |
| Hardness | 2800 HV5 |
| Elastic Modulus | 410GPa |
| Chemical Stability | Superior resistance to acid and alkali corrosion (including hydrofluoric acid) |
Advantages vs. Steel Bearings
- Higher Temperature Resistance: Superior mechanical stability at elevated temperatures
- Better Thermal Cycling Performance: Minimal clearance changes under temperature fluctuations
- Anti-Seizure Properties: Reduced thermal deformation minimizes friction-induced binding
- Oil-Free Operation: Self-lubricating properties enable reliable performance in high-vacuum environments
- Exceptional Corrosion Resistance: Impervious to acids, alkalis, and salts
- Electrical Insulation: Non-conductive, eliminating static discharge
- Non-Magnetic: Prevents magnetic particle adhesion in sensitive environments
