Performance Characteristics of Ceramic Materials in Rolling Bearings

Source:Luoyang mingzhen bearings steel balls Co.,Ltd | Updated: Mar 20, 2017


Practice has proved that bearing materials must have a dimensional stability in different temperature in order to ensure that bearings can operate and maintain the precise size and precise coordination in the temperature changing environment. Bearing materials must also have anti-corrosion and anti-decomposition ability in special circumstances. 

In short, ceramic materials used to make rolling bearing parts should have the following performance characteristics: 1. Low density. 2. Moderate elastic modulus. 3. Small thermal expansion coefficient. 4. High compressive strength. 5. High hardness and high toughness. 6. Good anti-rolling contact fatigue and flaking failure mode. 7. High temperature resistance, corrosion resistance and stability in special occasions.
