  • 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.
