Discussion on the Advantages of Ceramic Bearings

Ceramic bearings are an important mechanical foundation component. It has excellent performance that metal bearings cannot match, leading the way in the world of new materials in terms of high temperature resistance and super strength.
In the past decade, ceramic bearings have been increasingly widely used in various fields. Aerospace, navigation, nuclear industry, petroleum, chemical industry, light textile industry, machinery, metallurgy, electricity, food, locomotives, subways, high-speed machine tools, scientific research, national defense and military technology, and other fields need to work under special working conditions such as high temperature, high speed, deep cold, flammable, explosive, strong corrosion, vacuum, electrical insulation, non magnetic, dry friction, etc. The indispensable replacement role of ceramic bearings is gradually being recognized by people.
Ceramic bearings have the following advantages: high speed and acceleration ability - they can operate under conditions with DN values exceeding 3 million, and can reduce slipping, wear, and heat generation; Long lifespan and wear resistance - The fatigue life of all ceramic bearings is expected to be 10-50 times longer than that of all steel bearings, and the lifespan of hybrid ceramic bearings is also about 3-5 times longer than that of all steel bearings; Very little lubrication is required - the friction coefficient of ceramic materials is low, and ceramic bearings lubricated with oil still have a lubrication capacity that is not lower than traditional lubricants commonly used in steel bearings even when the lubricating oil becomes thin or lean; Wear-resistant and corrosion-resistant ceramic materials are more resistant to corrosion and wear due to their inert nature; High rigidity - due to the high elastic modulus of ceramic materials, their rigidity is 15-20% higher than that of ordinary steel bearings; High temperature resistance - all ceramic bearings can operate at temperatures above 500C; Low torque - According to the structure, the torque of ceramic bearings is reduced by about one-third; Non magnetic and non conductive - ceramic bearings are not damaged by magnetism or electricity.
