Customized SiC Sliding Bearing for Pumps

Customized Silicon Carbide Sliding Bearing

Ceramic sliding bearings represent cutting-edge tribological solutions deployed across demanding industrial sectors. These high-performance components utilize engineered ceramics - including silicon nitride (Si₃N₄), silicon carbide (SiC), and zirconium oxide (ZrO₂) - delivering significant operational advantages compared to conventional metallic bearings.

The exceptional corrosion resistance of these ceramic materials stands as a key benefit. Their inherent chemical stability enables reliable performance when exposed to aggressive media, from concentrated acids to saline environments, making them particularly suitable for chemical processing equipment and marine systems.

Furthermore, ceramic sliding bearings exhibit superior tribological characteristics. The ultra-smooth, extremely hard bearing surfaces significantly minimize frictional losses and wear rates. This translates to enhanced operational efficiency and extended service intervals for rotating equipment and associated components.

Another critical advantage lies in their thermal performance capabilities. Ceramic materials maintain structural integrity at elevated temperatures where metallic bearings would degrade, allowing deployment in high-heat applications including combustion engine systems and industrial thermal processes.

Ceramic bearings find extensive applications across multiple high-tech industries, including but not limited to:

• Aviation and aerospace systems
• Marine and navigation equipment
• Automotive components

• Petroleum and chemical processing
• Power generation and metallurgy
• Textile machinery and pump systems

• Precision electronic equipment
• Medical instrumentation
• Scientific research apparatus
• National defense systems

These bearings represent cutting-edge products utilizing advanced material technologies, demonstrating significant performance advantages in demanding operational environments. Their unique material properties enable superior functionality compared to conventional bearing solutions across these diverse applications.

Key properties of pressureless sintered silicon carbide:

• Ceramic bearings can be used for higher temperatures: ceramic materials can stably maintain their mechanical properties at high temperature, so they can be used in high temperature fields.
• Ceramic bearings are more suitable for the occasion of temperature change: because the thermal expansion coefficient of ceramic is smaller than that of steel, therefore, the clearance of ceramic bearings is less affected by temperature change than that of steel bearings, so that it can be used in a wider range of temperature fluctuations.
• Ceramic bearings have better anti-bite and anti-stuck performance: this is because the thermal expansion coefficient of ceramic is smaller than that of steel, which helps to reduce thermal deformation, so as to improve the anti-bite ability.
• Ceramic bearings can work without oil: ceramic has self-lubricating characteristics, and can also use medium for lubrication, so it can be applied to high vacuum and inconvenient lubrication occasions.
• Ceramic bearing is resistant to acid, alkali and salt corrosion, so it can be used in chemical corrosion occasions.
• Ceramic bearings can be used for occasions requiring electrical insulation and no static electricity: the ceramics produced by our company are not conductive, without static electricity, and will not produce the current ablative phenomenon of steel bearings.
• Ceramic bearings can be used in magnetic environment: ceramic is not magnetic, magnetic foreign body or abrasive particles are not easy to adhere to the channel, can reduce abrasive wear.

We have three factories in China, can meet the needs for different customers, and also we have advanced pressing, sintering and processing machines.
