1、 Technological characteristics of graphite bearing:

1. High temperature resistance: graphite is one of the most high temperature resistant materials known. Its melting point is 3850 ℃ ± 50 ℃, and its boiling point is 4250 ℃. The loss of graphite is the smallest at 7000 ℃ for 10s, and the loss of graphite is 0.8% by weight. Therefore, the high temperature resistance of graphite is very outstanding.

2. Special thermal shock resistance: graphite has good thermal shock resistance, that is, when the temperature changes suddenly, the coefficient of thermal expansion is small, so it has good thermal stability, and will not produce cracks when the temperature changes rapidly.

3. Thermal conductivity and conductivity: graphite has good thermal conductivity and conductivity. Compared with general materials, it has high thermal conductivity. It is 4 times higher than stainless steel, 2 times higher than carbon steel and 100 times higher than general non-metal.

4. Lubricity: the lubricity of graphite is similar to molybdenum disulfide, and the friction coefficient is less than 0.1. The lubricity changes with the scale size. The larger the scale, the smaller the friction coefficient, and the better the lubricity.

5. Chemical stability: under normal temperature, graphite has good chemical stability, can resist the corrosion of acid, alkali and organic solvent.
