Customized SSIC Sliding Bearing Sleeve for Pumps, 1650℃ Max Temp

Customized SSIC Pressureless Sintered Sliding Bearing Sleeve For Pump

Engineered from premium-grade silicon nitride (Si3N4), silicon carbide (SiC), and zirconia (ZrO2), our ceramic sliding bearings outperform conventional steel bearings with exceptional durability and reliability. These high-performance components are specifically designed to withstand extreme conditions, including corrosive environments, elevated temperatures, and intensive wear scenarios, making them ideal for demanding industrial, automotive, and aerospace applications.

• 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.

Key properties of pressureless sintered silicon carbide

1. Ceramic bearings can be used for higher temperatures: ceramic materials can stably maintain their mechanical properties at high temperature.
2. Ceramic bearings are more suitable for the occasion of temperature change: the thermal expansion coefficient of ceramic is smaller than that of steel.
3. Ceramic bearings have better anti-bite and anti-stuck performance: helps to reduce thermal deformation.
4. Ceramic bearings can work without oil: ceramic has self-lubricating characteristics.
5. Ceramic bearing is resistant to acid, alkali and salt corrosion.
6. Ceramic bearings can be used for occasions requiring electrical insulation and no static electricity.
7. Ceramic bearings can be used in magnetic environment: ceramic is not magnetic.

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

Our company logo is ZXSQ and CSQ, and possesses eleven invention patents for utility models. The company now has a high-quality professional team consisting of dozens of members, to provide you with high-quality and perfect service, according to customer requirements to order a variety of bearing products.

Since the year of 1982 we have accumulated abundant experience in the production over the past more than 40 years, devoting ourselves whole-heartedly to the research and development of ceramic bearing material, our processing technique and improvement of our equipments. Having undergone several evolution and transformation, our company has now become the leading enterprise in China domestic market in the fields of ceramic bearing and ceramic material products.

According to the structure difference, it can be divided into: external gear pump and internal gear pump. Our company has ample production experience of both kind of the gear pump sliding bearing in material of silicon carbide. We did supply these SSiC sliding bearing for Germany Witte for many years.
