Customized Silicon Carbide Sliding Bearing Sleeve
 
Description of Sliding Bearing Sleeve:
 

Silicon carbide sliding bearing sleeves are high-performance ceramic components designed for extreme operating conditions. Manufactured from premium-grade SiC, these sleeves exhibit exceptional hardness, outstanding thermal conductivity, and superior chemical inertness, making them ideal for corrosive, high-temperature, and high-wear environments.

Their low coefficient of thermal expansion ensures dimensional stability across temperature ranges from -200°C to 16500°C. Common applications include pump systems in chemical processing, mechanical seals in refineries, bearings in semiconductor manufacturing, and components in aerospace propulsion systems. Compared to traditional metal sleeves, SiC versions demonstrate 5-8x longer service life in abrasive media while reducing maintenance downtime by up to 60%.

Applications:

Ceramic bearings find extensive applications across diverse industries, including aviation, aerospace, marine engineering, petroleum, chemical processing, automotive manufacturing, electronic equipment, metallurgy, power generation, textile machinery, pump systems, medical instruments, scientific research, and national defense. As high-tech products utilizing advanced materials, they represent cutting-edge technological solutions for demanding operational environments.
 
Properties:

The advantages of all-ceramic bearings compared with steel bearings are:

1. 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.

2. 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.

3. 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.

4. 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.

5. Ceramic bearing is resistant to acid, alkali and salt corrosion, so it can be used in chemical corrosion occasions.

6. 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.

7. 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.
