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.
3. In which industries are ceramic bearings commonly used?
Ceramic bearings are widely used in:

  Packaging equipment
  Renewable energy (e.g., wind turbines)
  Aerospace and automotive
  Medical devices
  Chemical processing
  High-precision tools
4. Can ceramic bearings handle high temperatures?
Yes, ceramic bearings are highly resistant to heat and can operate in temperatures exceeding 1,000°C, depending on the material used.

5. Are ceramic bearings suitable for corrosive environments?
Absolutely! Ceramic bearings are non-reactive to most chemicals, making them ideal for use in highly corrosive environments.

6. What is the lifespan of ceramic bearings?
Ceramic bearings typically last much longer than steel bearings due to their wear resistance and durability. However, the exact lifespan depends on the operating conditions and maintenance practices.

7. How do I maintain ceramic bearings?
Ceramic bearings require minimal maintenance, but to ensure longevity:

  Use the correct lubrication when necessary.
  Keep them clean and free from contaminants.
  Follow proper installation procedures.
