Product Description
Customized Ceramic Sliding Bearing Sleeve in High Temperature Applications
High Temperature Ceramic Bearing Manufacturers - Silicon Carbide (SSiC) Sleeve
Ceramic sliding bearings are precision-engineered from high-performance materials like silicon nitride (Si3N4), silicon carbide (SiC), and zirconia (ZrO2), offering superior durability and reliability compared to traditional steel bearings. Designed for industrial, automotive, and aerospace applications, these bearings excel in corrosive, high-temperature, and high-wear environments.
Key Advantages
- Extreme Corrosion Resistance - Withstands harsh chemicals, acids, and marine environments, ideal for chemical processing, pumps, and offshore equipment.
- Ultra-Low Friction & Wear - Smoother, harder ceramic surfaces minimize friction, reducing energy loss and extending bearing lifespan by 5-10X over metal alternatives.
- High-Temperature Stability - Operates reliably up to 1,400°C, perfect for turbines, engines, and industrial furnaces.
- Lightweight & Non-Magnetic - Reduces rotational inertia and eliminates magnetic interference, critical for aerospace and medical devices.
Applications
Ceramic bearings can be widely used in aviation, aerospace, navigation, petroleum, chemical, automotive, electronic equipment, metallurgy, electric power, textile, pump, medical instruments, scientific research and national defense and other fields, is the application of new materials of high-tech products.

Advantages of All-Ceramic Bearings Compared with Steel Bearings
- Higher temperature capability: ceramic materials maintain mechanical properties at high temperatures
- Better performance with temperature fluctuations: smaller thermal expansion coefficient reduces clearance changes
- Improved anti-bite and anti-stuck performance: reduced thermal deformation enhances performance
- Oil-free operation possible: self-lubricating characteristics enable use in high vacuum environments
- Resistant to acid, alkali and salt corrosion: suitable for chemical processing applications
- Electrical insulation: non-conductive with no static electricity generation
- Non-magnetic: ideal for magnetic environments where particle adhesion must be minimized
