High performance Industrial Zirconia Ceramic Ball Bearing ZrO2 Ceramic Roller Groove Ring

﹡Product Overview

Our zirconia ceramic ball bearings and groove rings (ZrO₂) represent the pinnacle of bearing technology, offering superior wear resistance, corrosion immunity, and high-temperature stability compared to traditional steel bearings. Engineered for mission-critical applications where failure is not an option, these advanced ceramic components deliver longer service life, reduced maintenance, and enhanced performance across multiple industries.

﹡Key Technical Specifications

✔ Exceptional Hardness - Mohs 8.5 hardness for outstanding wear resistance

✔ Corrosion Proof - Immune to rust, acids, and harsh chemicals

✔ High-Temperature Capable - Stable up to 800°C (1472°F) continuous operation

✔ Non-Magnetic & Electrically Insulating - Ideal for sensitive electronic environments

✔ Lightweight - 60% lighter than steel for reduced centrifugal forces

✔ Self-Lubricating - Low friction coefficient (0.1-0.15) for dry running capability

﹡Competitive Advantages

✅ Longer Service Life - 3-5× lifespan vs steel bearings in harsh conditions

✅ Reduced Downtime - Virtually eliminates corrosion-related failures

✅ Energy Efficient - Lower friction reduces power consumption

✅ Maintenance-Free - Often operates without lubrication

✅ Custom Engineered - Solutions tailored to your exact requirements

﹡Production process

1. Grind and crush the raw materials to be slurry or powder

2. se-different method to making the slurry or powder into semi-finished products

3. Put the semi-finished products into the kiln for dewaxing and sintering;

4. After forming and sintering, Ceramic Sleeves products can also be processed by subsequent CNC precision machining according to the drawing requirements. Then Q/C test.

5. Finally package Ceramic Sleeves by bubble paper or cartons and place it on tray for delivery
