Custom ZrO2 Ceramic Step Sleeve Bearing for Pumps

 
Customized ZrO2 Sliding Bearing Sleeve with Step
 
Product overview
 

The Zirconia Stepped Sleeve is a high-performance ceramic component made from Yttria-Stabilized Zirconia (YSZ), offering exceptional thermal resistance, corrosion resistance, high hardness, and low thermal conductivity. It is widely used in metallurgy, semiconductors, chemical processing, aerospace, and precision machinery, particularly in extreme environments requiring high-temperature insulation, wear resistance, and chemical inertness.

Key Features:

• Extreme Temperature Resistance (Up to 2200°C)
• Superior Thermal Shock Resistance
• High Chemical Inertness (Resistant to acids, alkalis, and molten metals)
• High Hardness & Wear Resistance (Vickers Hardness ≥1200 HV)
• Low Thermal Conductivity (Excellent Insulation Performance)
• Precision Machining (High dimensional accuracy for demanding applications)

Technical Specifications

Typical Applications

• High-Temperature Furnaces & Melting Equipment (Crucibles, Thermocouple Protection Tubes)
• Semiconductor Manufacturing (Wafer Processing, CVD Reactor Components)
• Chemical Corrosion-Resistant Parts (Pump Bushings, Valve Seals)
• Aerospace (Thermal Insulation Components, Jet Engine Parts)
• Precision Machinery (High-Precision Bearing Sleeves, Wear-Resistant Guides)
