Silicon Carbide (SiC) sleeves are high-performance ceramic components manufactured from SiC. They exhibit exceptional wear resistance, corrosion resistance, high hardness, and thermal stability, making them ideal for bearings, seals, and transmission systems in harsh environments across industries like chemical processing, machinery, semiconductors, and energy.
- Superior Hardness & Wear Resistance: Mohs hardness of 9.5 (second only to diamond), ensuring extended service life.
- Excellent Corrosion Resistance: Resists strong acids, alkalis, and organic solvents, suitable for chemical equipment.
- High-Temperature Stability: Maintains performance up to 1600°C without oxidation or deformation.
- Low Thermal Expansion: High thermal conductivity and thermal shock resistance for rapid temperature cycling.
- Self-Lubricating: Low friction coefficient reduces energy consumption and maintenance.
- Chemical Industry: Pumps, valves, reactor seals.
- Machinery: High-speed bearings, precision components.
- Semiconductors: Wafer handling fixtures.
- New Energy: Photovoltaic and lithium battery production equipment.

Ceramic bearings maintain superior mechanical stability at elevated temperatures, making them ideal for extreme heat applications where steel bearings would degrade.
Due to their low thermal expansion coefficient, ceramic bearings experience minimal clearance changes under temperature fluctuations, ensuring reliable operation across a wider range of conditions.
The reduced thermal deformation of ceramic materials minimizes friction-induced binding, significantly improving resistance to seizure and galling.
Ceramic bearings exhibit self-lubricating properties and can utilize process media for lubrication, enabling reliable performance in high-vacuum environments or where traditional lubrication is impractical.
Unlike steel, ceramics are impervious to acids, alkalis, and salts, making them perfect for harsh chemical processing, marine, and corrosive industrial applications.
Our ceramic bearings are non-conductive, eliminating static discharge and preventing electrical arcing damage--common issues with conductive steel bearings.
Ceramic's non-magnetic nature prevents magnetic particle adhesion, reducing abrasive wear and ensuring smooth operation in MRI equipment, semiconductor tools, and other magnetic-sensitive environments.


We have three factories in China, equipped with advanced pressing, sintering and processing machines to meet diverse customer needs. Our company logos are ZXSQ and CSQ, and we possess eleven invention patents for utility models.
Since 1982, we have accumulated over 40 years of experience in ceramic bearing production, continuously improving our materials, processing techniques, and equipment. We have become a leading enterprise in China's ceramic bearing and ceramic material products market.
We specialize in both external and internal gear pump sliding bearings in silicon carbide material, with extensive experience supplying SSiC sliding bearings to international clients like Germany's Witte.
