Customized Silicon Carbide Sliding Bearing for Gear Pumps
Industrial Ceramic Sliding Bearing for Harsh Environments
Customized Silicon Carbide Sliding Bearing Sleeve. Ceramic sliding bearings are advanced bearing technology used in industrial, automotive, and aerospace applications. Constructed using ceramic materials like silicon nitride, silicon carbide or zirconia, they offer superior performance compared to traditional steel bearings.
Key Advantages
- Corrosion Resistance: Highly resistant to harsh chemicals and environments, ideal for chemical processing and marine applications
- Reduced Friction: Smoother, harder surfaces minimize friction and wear, extending component lifespan
- High Temperature Tolerance: Maintains integrity in extreme heat conditions up to 1650℃
Applications
Widely used in aviation, aerospace, navigation, petroleum, chemical processing, automotive, electronics, metallurgy, power generation, textiles, pumps, medical equipment, and defense applications.

Ceramic vs Steel Bearing Advantages
- Superior high temperature performance (stable mechanical properties)
- Better performance with temperature fluctuations (lower thermal expansion)
- Improved anti-bite and anti-stuck performance
- Can operate without lubrication (self-lubricating properties)
- Resistant to acid, alkali and salt corrosion
- Electrical insulation and no static electricity generation
- Non-magnetic properties prevent abrasive particle adhesion
