For tight tolerance or special surface requirements, CERAMPRO provides precision ceramic machining, grinding, polishing, and inspection support.
Please share your drawings, tolerance requirements, surface finish, working media, and estimated order quantity for a custom SiC ceramic sleeve quotation.
Made from high-performance silicon carbide ceramic (SiC), these sleeves offer high hardness, good corrosion resistance, and stable performance in harsh industrial environments. They are commonly used as pump sleeves, shaft sleeves, bushings, mechanical seal parts, and wear-resistant liners.
CERAMPRO can manufacture custom silicon carbide ceramic sleeves according to customer drawings, samples, equipment structures, and operating conditions. We support material selection, forming, sintering, precision ceramic machining, grinding, polishing, inspection, and batch production.
This product can also be used with other custom ceramic pump components for fluid control, sealing, and wear-resistant applications.
| Parameter | Typical Value | Application Value |
| Material Grade | SSiC / RBSiC / SiSiC / NSiC | Selected according to wear, corrosion, temperature, and size requirements. |
| Hardness | Approx. 22–28 GPa | Helps improve wear resistance in abrasive and high-friction applications. |
| Density | Approx. 3.10–3.15 g/cm³ | Provides high rigidity with relatively low weight for sleeve and bearing applications. |
| Thermal Conductivity | Approx. 100–130 W/(m·K) | Supports heat dissipation in mechanical seals and rotating pump parts. |
| Thermal Shock Resistance | Good, depending on material grade and structure | Suitable for temperature-changing and high-temperature working conditions. |
| Max Service Temperature | Up to approx. 1350°C in air, depending on grade | Suitable for many high-temperature equipment and thermal process applications. |
| Chemical Resistance | Good resistance to many acids, alkalis, solvents, and corrosive liquids | Final compatibility should be confirmed according to the actual working media. |
| Surface Finish | Ground or polished surface available | Suitable for mechanical seals, pump sleeves, bushings, and precision matching areas. |
| Customization | ID, OD, length, grooves, chamfers, holes, and sealing surfaces | Manufactured according to drawings, samples, or equipment assembly requirements. |
Note: The above values are typical reference data. Final specifications should be confirmed according to material grade, drawings, working media, tolerance requirements, surface finish, and inspection standards.
It is used as a pump sleeve, shaft sleeve, bushing, mechanical seal component, wear sleeve, or liner in abrasive, corrosive, and high-temperature equipment.
Silicon carbide ceramic offers higher hardness, better wear resistance, good corrosion resistance, and stable performance in harsh industrial conditions.
CERAMPRO can support SSiC, RBSiC / SiSiC, and NSiC material options according to part size, temperature, working media, and machining requirements.
Yes. We can manufacture custom silicon carbide ceramic sleeves according to drawings, samples, equipment structures, tolerances, and surface finish requirements.
Yes. ID, OD, end faces, grooves, chamfers, and sealing areas can be ground or polished according to drawing requirements.
Yes. SiC ceramic sleeves are suitable for many slurry pump and abrasive media applications due to their high hardness and wear resistance.
Silicon carbide ceramic has good resistance to many chemical liquids and corrosive media. Final compatibility should be confirmed according to the actual working media.
Please provide drawings, material requirements, ID and OD tolerances, surface finish requirements, working media, operating temperature, sample quantity, and estimated batch demand.
Standard silicon carbide ceramic sleeves usually take about 20–35 days. Large, complex, or high-precision custom sleeves may require about 40–60 days.
CERAMPRO can also manufacture silicon carbide bushings, seal rings, mechanical seal parts, liners, nozzles, pump components, and other custom SiC ceramic parts.
