(Summary description)

In recent years, ceramic bearings are more and more widely used in aviation, aerospace, navigation, petroleum, chemical industry, automobile, electronic equipment, metallurgy, electric power, textile, pump, medical equipment, scientific research and national defense and military fields. Ceramic bearings now more and more obvious advantages in the use of new products, According to the specific understanding of Zhonghua bearing network to tell you about the use of ceramic bearing material have what advantages.

Harbin bearing

Ceramic bearing material advantages, which mainly include the following:

1. High speed: Ceramic bearing has the advantages of cold resistance, small stress elasticity, high pressure resistance, poor thermal conductivity, light dead weight, low friction coefficient, etc., which can be used in high-speed spindles with 12,000 RPM ~ 75,000 RPM and other high-precision equipment;

2, high temperature resistance: ceramic bearing material itself has high temperature resistance of 1200℃, and good self-lubrication, the use temperature between 100℃ and 800℃ does not produce expansion caused by temperature difference. Can be used in furnace, plastic, steel and other high temperature equipment;

3, corrosion resistance: ceramic bearing material itself has corrosion resistance characteristics, can be used in strong acid, strong alkali, inorganic, organic salt, sea water and other fields, such as: electroplating equipment, electronic equipment, chemical machinery, shipbuilding, medical equipment, etc..

4, antimagnetic: ceramic bearing due to no magnetic dust absorption, can reduce the bearing in advance of spalling, noise, etc. Can be used in demagnetization equipment. Precision instruments and other fields.

5, electrical insulation: ceramic bearings due to high electrical resistance, can avoid arc damage bearings, can be used in a variety of electrical equipment insulation requirements.

6. Vacuum: Due to the unique oil-free self-lubricating characteristics of ceramic materials, silicon nitride all-ceramic bearing can overcome the difficulty that ordinary bearings cannot be lubricated in ultra-high vacuum environment.
