Hybrid Ceramic Bearings

5041 Products

Hybrid Ceramic Bearings are a type of advanced bearing that combine the best attributes of both steel and ceramic materials. In these bearings, the inner and outer races are typically made of steel, while the rolling elements are made of ceramic. This unique composition offers several advantages over traditional all-steel or all-ceramic bearings.


Features of Hybrid Ceramic Bearings

Material Combination

  • Steel Races: Offer high strength and durability.
  • Ceramic rolling elements: Usually made of materials like Silicon Nitride (SiN4), Alumina Oxide (Al2O3), Zirconia Oxide (ZrO2), or Silicon Carbide (SiC), these rolling elements (balls or rollers) are lighter, harder, and more wear-resistant than steel balls.

 Performance Advantages of Hybrid Ceramic Bearings

  • Good thermal insulation and High temperature strength
  • Low thermal conductivity
  • Resistance to corrosion and acids except HF acid
  • Avoid water vapor as it breaks Yttria
  • Minimal abrasive wear
  • Good dimensional stability
  • Low centrifugal forces, no seizing
  • Lubricant-free running
  • Increased Durability
  • Medium friction (HV>1400): Rotation speed increased from 30 to 170% compared to regular steel bearings
  • Life time is 50% more than regular steel bearings.
