Designed for pumps with maximum temperature resistance up to 1650℃
Product Overview
Our customized silicon carbide sliding bearing sleeves are precision-engineered from advanced ceramic materials including silicon nitride (Si3N4), silicon carbide (SiC), and zirconia (ZrO2). These high-performance bearings deliver superior durability and reliability compared to traditional steel bearings, specifically designed for demanding industrial, automotive, and aerospace applications in corrosive, high-temperature, and high-wear environments.
Key Advantages
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
Applications
Ceramic bearings are widely used in aviation, aerospace, navigation, petroleum, chemical, automotive, electronic equipment, metallurgy, electric power, textile, pump, medical instruments, scientific research, and defense applications, representing high-tech products utilizing advanced materials.
Superior resistance to acid and alkali corrosion (including hydrofluoric acid)
Ceramic vs Steel Bearing Advantages
Higher Temperature Capability - Ceramic materials maintain mechanical properties at elevated temperatures, suitable for high-temperature applications
Superior Temperature Change Performance - Lower thermal expansion coefficient reduces clearance variations across temperature fluctuations
Enhanced Anti-Bite and Anti-Stuck Performance - Reduced thermal deformation improves resistance to binding
Oil-Free Operation - Self-lubricating characteristics enable use in high vacuum and difficult-to-lubricate environments
Corrosion Resistance - Withstands acid, alkali, and salt corrosion for chemical processing applications
Electrical Insulation - Non-conductive properties eliminate static electricity and prevent current ablation
Non-Magnetic Performance - Magnetic particles don't adhere to bearing channels, reducing abrasive wear
Manufacturing Capabilities
We operate three factories in China equipped with advanced pressing, sintering, and processing machinery to meet diverse customer requirements. Our company brands ZXSQ and CSQ are supported by eleven utility model invention patents. With a professional team of dozens of experts, we provide high-quality customized bearing solutions tailored to specific application needs.
Since 1982, we have accumulated over 40 years of ceramic bearing production experience, continuously advancing material research, processing techniques, and equipment improvements. Through multiple evolutions, we have become a leading enterprise in China's ceramic bearing and ceramic materials market.
We specialize in both external and internal gear pump sliding bearings in silicon carbide material, with extensive experience supplying SSiC sliding bearings to companies like Germany's Witte for many years.
