Product Introduction

Our zirconia ceramic single-row ball bearings represent the pinnacle of high-temperature, high-speed bearing technology. Engineered from high-purity ZrO₂ (zirconia), these premium bearings deliver exceptional thermal stability, electrical insulation, and corrosion resistance - making them ideal for applications where conventional steel bearings fail. With capabilities to withstand temperatures up to 800°C (1472°F) and operate at speeds 50% higher than steel equivalents, our ceramic bearings are revolutionizing performance in aerospace, semiconductor, and high-temperature processing industries.

High-Speed High Temperature Ceramic Ball Bearing Zirconia Insulator with High Quality

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
