FAQ

1. What are ceramic bearings?
Ceramic bearings are bearings made from advanced ceramic materials such as Zirconia (ZrO2) or Silicon Nitride (Si3N4). They are known for their high strength, wear resistance, and ability to perform in extreme conditions.

2. What are the advantages of ceramic bearings over steel bearings?
Ceramic bearings offer several advantages, including:

  Higher Durability: Resistant to wear, corrosion, and high temperatures.
  Lighter Weight: Up to 40% lighter than steel bearings.
  Non-Magnetic & Electrically Insulating: Ideal for sensitive applications.
  Low Friction: Reduces energy loss and heat generation.
