MS2030 Carbon Graphite Seals and Bearings
Carbon Graphite is a non-metal material with excellent self-lubricant ability, which offers the material great advantage in seals and bearings application.
Advantages:
1. Good chemical resistance, depends on the impregnated resin or metal.
2. Excellent self lubricant ability.
3. Good thermo conductive ability.
4. Low thermo expansion rate.
5. Good thermo shock resistance.
6. Good temperature resistance for metal impregnated.
7. Good mechanical strength and easily machined to varies of shapes.
Availability:
1. Resin-Impregnated Carbon Graphite Furan, Phenolic, Epoxy, etc.
Good chemical resistance but only applied in normal temperature.
2. Metal-Impregnated Carbon Graphite Copper, Antimony, Babbitt, Silver, etc.
Good chemical resistance, temperature resistance, and mechanical strength.
Application:
1. Mechanical seal tribological face.
2. Canned motor pump bearing.
3. Bearing operating immersed in fuels.
