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.
| Property | Value |
|---|---|
| Max Temperature | Up to 1650℃ |
| Density | 3.15-3.18 g/cm³ |
| Thermal Expansion | 4.0 (10-6/℃) |
| Thermal Conductivity | 120 W/m°K |
| Hardness | 2800 HV5 |
| Elastic Modulus | 410 GPa |
| Chemical Stability | Superior resistance to acid and alkali corrosion (including hydrofluoric acid) |
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, capable of meeting different customer needs, with advanced pressing, sintering and processing machines.
Our company logos are ZXSQ and CSQ, and we possess 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 1982 we have accumulated abundant experience in production over more than 40 years, devoting ourselves whole-heartedly to the research and development of ceramic bearing material, our processing technique and improvement of our equipment.
Having undergone several evolutions and transformations, our company has now become the leading enterprise in China's domestic market in the fields of ceramic bearing and ceramic material products.
We cooperate with raw material suppliers to ensure product quality and profit stability without being affected by international raw material price fluctuations. At the same time with raw material production technology, when necessary, we can produce raw materials by ourselves.
We adhere to customer demand as the guidance, and strive to provide customers with quality products and after-sales service, create value for customers, and be customers' partner. Welcome to discuss cooperation!
