Introduction

Ceramic ball bearings have become critical components in aerospace, medical devices, and high-performance machinery due to their superior thermal stability and corrosion resistance. Global buyers face persistent challenges in identifying suppliers that balance ISO-compliant manufacturing with cost-effective solutions while mitigating supply chain disruptions.

Technical Specifications & International Standards

Premium ceramic bearings combine silicon nitride (Si3N4) or zirconium oxide (ZrO2) balls with stainless steel races. Key metrics include:

• ABEC 5/7 tolerance levels
• Operating range: -40°C to 300°C
• DN value: >1.5 million
