Alumina Ceramic Components Lightweight Wear-Resistant And Chemically Resistant For Precision Machinery Applications
Our premium alumina ceramic bushings and guide columns are manufactured from ultra-high purity 99.7% Al₂O₃ material, specifically engineered for high-precision, wear-resistant applications. ISO 6474-1 certified with exceptional hardness (HV1800-2000) and ultra-low friction coefficient (0.07), these components achieve IT5-grade dimensional accuracy, representing a revolutionary solution for precision machinery applications.
Semiconductor Equipment: Wafer handling robot guide columns, lithography machine precision bushings
Medical Devices: Surgical robot joint bushings, CT scanner rotating guide components
Automation Lines: Linear module guide columns, industrial robot wrist joints
Precision Instruments: Optical platform adjustment bushings, measuring equipment guide mechanisms
Automotive Manufacturing: Turbocharger bearing sleeves, high-pressure fuel pump guide columns
✦ Nanometer Precision: Roundness ≤0.5μm, cylindricity ≤1μm
✦ Superior Wear Resistance: Only 1/15 the wear rate of metal components
✦ Self-Lubricating: Dry friction coefficient 0.07-0.12
✦ Chemical Resistance: Withstands pH1-14 acidic/alkaline media
✦ Lightweight: Density 3.95g/cm³, 60% lighter than steel
