What are the uses of ceramic bearings?

Ceramic bearings have a wide range of applications, mainly including aviation, aerospace, navigation, petroleum, chemical, automotive, electronic equipment, metallurgy, 

power, textile, pump, medical equipment, scientific research, and national defense and military fields. Ceramic bearings have characteristics such as high temperature 

resistance, cold resistance, wear resistance, corrosion resistance, magnetic and electrical insulation resistance, oil-free self-lubricating, and high speed, which make them 

perform well in extremely harsh environments and special working conditions.

Specifically, ceramic bearings have important applications in the following fields:

High speed application: Ceramic bearings perform well in high-speed operation. For example, in jet turbine engines, silicon nitride ceramic bearings generate 30% -50% 

less heat than standard steel bearings, making them suitable for high-speed operating environments.

High temperature applications: Ceramic bearings can maintain good performance in high-temperature environments, even working normally under conditions above 

1000 ℃, which makes them important for high-temperature industries.

Low temperature application: In rocket engines that provide ultra-low temperature propulsion, ceramic bearings can work stably in low temperature environments and 

adapt to extreme temperature changes.

Medical devices: The application of ceramic bearings in medical devices has improved the accuracy and durability of the equipment, especially in surgical instruments 

that require high speed and high precision.

Research and Defense Military: Ceramic bearings also have important applications in the fields of research and defense military, especially in equipment that requires 

high reliability and performance.

In summary, ceramic bearings play an irreplaceable role in many high-tech fields due to their excellent physical and chemical properties. With the advancement of 

technology, their application scope will further expand. ‌
