Zirconia Bearing Deatails:

  1. Zirconia ceramic bearings offer magnetoelectric insulation, wear and corrosion resistance, self-lubrication, and withstand extreme temperatures.

  2. Suitable for harsh environments and special working conditions.

  3. Made from Zirconia (ZrO2) ceramic materials for rings and rolling elements.

  4. PTFE is standard for retainers, with options like glass fiber reinforced nylon 66, special engineering plastics, stainless steel, and brass available.

Zirconia Bearings Features:

  • Corrosion Resistance: Highly resistant to most strong acids (except hydrofluoric), alkalis, salts, and seawater. Suitable for harsh environments like plating, electronics, chemical processing, shipbuilding, and medical equipment.
  • High-Temperature Performance: Operates effectively at 300°C - 800°C (with balls), 180°C - 260°C (with retainers). Ideal for furnace kilns and manufacturing equipment.
  • Self-Lubricating: Low friction coefficient and smooth surface reduce lubrication needs. Silicon nitride variants offer excellent self-lubrication, beneficial in vacuum environments.
  • Non-Magnetic: Absence of magnetism and dust absorption prevents premature wear and noise. Suitable for demagnetization equipment and sensitive instruments.
  • Electrical Insulation: High electrical resistance prevents arcing damage. Safe for power equipment with insulation requirements.
  • Low Density: Lower density than steel reduces centrifugal force on the outer ring by up to 40%, extending service life.
  • Thermal Stability: Less affected by thermal expansion and contraction than steel, ensuring consistent clearance in environments with significant temperature fluctuations.
  • High Elastic Modulus: Resists deformation under stress, enabling higher speeds and precision.
