Made from high-purity alumina ceramic, this ceramic shaft plug and sleeve set is designed for wear-resistant and corrosion-resistant pump, valve and fluid control applications. Custom ID, OD, length, clearance fit and surface finish can be manufactured based on customer drawings.
This alumina ceramic shaft plug and sleeve set is commonly used in ceramic pump components, valve assemblies, metering pumps, chemical pumps, fluid control systems, rotating shaft protection, automation equipment and precision machinery.
It is suitable for working conditions where metal sleeves may face wear, corrosion, sticking or dimensional instability during long-term operation.
Sample production usually takes 15–25 working days after drawings, material and tolerance requirements are confirmed.
Bulk order lead time is usually 25–40 working days, depending on quantity, machining difficulty, polishing requirements and inspection standards.
CERAMPRO custom alumina ceramic shaft sleeve and plug sets are designed for pump, valve and fluid control systems where metal parts may wear, corrode or lose stable fit during long-term operation.
Made from high-purity alumina ceramic, these components provide good wear resistance, corrosion resistance and dimensional stability. The shaft sleeve and plug can be manufactured according to customer drawings, including ID, OD, length, clearance, tolerance and surface finish.
This product is commonly used in ceramic pump components, metering pumps, chemical pumps, valve assemblies, rotating shaft protection and precision fluid control equipment.
Alumina ceramic is a practical material choice for precision wear parts. It combines hardness, corrosion resistance, electrical insulation and stable dimensions, making it suitable for pump, valve and fluid control applications.
| Material | Typical Use |
|---|---|
| 95% Alumina Ceramic | General wear-resistant ceramic parts |
| 99% Alumina Ceramic | Parts requiring better purity and corrosion resistance |
| 99.5%–99.7% Alumina Ceramic | Precision pump, valve and fluid control components |
| ZTA Ceramic | Applications requiring higher toughness and mechanical strength |
This alumina ceramic shaft sleeve and plug set is suitable for equipment that requires stable fit, wear resistance and corrosion resistance.
Alumina ceramic has high hardness and performs well in sliding, rotating and abrasive working conditions. It is a suitable option when metal sleeves face wear, galling or surface damage.
The ceramic sleeve and plug can be used in many fluid and chemical environments where metal parts may corrode or degrade.
ID, OD, length and clearance can be controlled according to drawings to support smooth movement and stable assembly.
Grinding, honing and polishing are available for applications that require lower friction, better sealing or smoother motion.
CERAMPRO supports custom ceramic sleeves, plugs and matched ceramic assemblies based on drawings, samples or actual working conditions.
Specifications can be customized based on drawings, samples and application requirements. Related material: Alumina Ceramic Components.
