Customized SSIC Sliding Bearing Sleeve for Pumps

Customized Silicon Carbide Sliding Bearing 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.

• 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.

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.

1. Ceramic bearings can be used for higher temperatures: ceramic materials can stably maintain their mechanical properties at high temperature.
2. More suitable for temperature changes: thermal expansion coefficient is smaller than steel, allowing use in wider temperature fluctuations.
3. Better anti-bite and anti-stuck performance: reduces thermal deformation to improve anti-bite ability.
4. Can work without oil: self-lubricating characteristics allow use in high vacuum and inconvenient lubrication occasions.
5. Resistant to acid, alkali and salt corrosion: suitable for chemical corrosion environments.
6. Electrical insulation and no static electricity: ceramics are non-conductive without static electricity.
7. Can be used in magnetic environments: ceramic is non-magnetic, preventing abrasive particles from adhering to channels.
