99.5% Alumina Ceramic Insulated Bearings Offering Exceptional Insulation And Precision Retention

99.5% Alumina Ceramic Insulated Bearings Offering Exceptional Insulation And Precision Retention

Product Introduction

Alumina ceramic insulated bearings are manufactured using 99.5% high-purity alumina ceramic material, offering exceptional electrical insulation properties and mechanical strength. By integrating alumina ceramic layers on the bearing rings' surfaces, these bearings provide complete electrical insulation, effectively preventing electrical corrosion - making them ideal for applications with electrical current risks.

Primary Applications

• Electric Motors: Variable frequency motors, generator insulated bearings

• Rail Transit: High-speed train traction motors

• Wind Power: Wind turbine generator insulated bearings

• Medical Equipment: MRI and medical imaging systems

• Special Environments: Strong electromagnetic fields, highly corrosive conditions
