Antimony-impregnated graphite is a new type of self-lubricating sealing and anti-wear material. It is made of carbon star material impregnated with molten metal antimony.
1.Product Introduction
Antimony-impregnated graphite is a new type of self-lubricating sealing and anti-wear material. It is made of carbon star material impregnated with molten metal antimony. The melting point of antimony is 630.5℃. It is brittle and hard. It is not easy to oxidize at room temperature and has corrosion resistance. Therefore, antimony-impregnated graphite has high hardness and can withstand high temperatures of 500℃. It is suitable for use in water, air, acid, alkali and other media. It is an ideal sealing and anti-wear material for petroleum, chemical, chemical fiber, oil refining, machinery, metallurgy, casting and other departments. At the same time, graphite can also be impregnated with copper, bus alloy, impregnated with silver, etc.
Antimony-impregnated graphite bearing is a new type of bearing product made by special technology, combining the excellent thermal conductivity and hardness of antimony metal materials with the self-lubricating characteristics and corrosion resistance of graphite materials. This bearing product is suitable for a variety of working conditions, especially under high temperature, high pressure, fast sliding speed and other conditions. It shows good performance.

1. Self-lubricating performance: graphite as a good solid lubricating material, can work in oil-free or oil-less environment, reduce the use of lubricating oil, reduce maintenance costs.
2. High thermal conductivity: The thermal conductivity of antimony material is good, which helps the bearing to effectively dissipate heat in high-speed operation or high temperature environment, prevent the bearing from overheating, and improve the operating stability.
3. Wear resistance and corrosion resistance: graphite material itself has excellent wear resistance and corrosion resistance, combined with antimony material, this characteristic is further strengthened, especially suitable for the working environment with corrosive media.
4. Impact load resistance: The good ductility and toughness of antimony provide a certain degree of impact load absorption capacity for the bearing, which improves the smoothness of equipment operation.
5. Good temperature resistance: the combination of antimony and graphite gives the bearing the ability to maintain dimensional stability in the environment of large temperature changes, and is suitable for working environments with large temperature differences.
6.The manufacturing process of impregnated antimony graphite bearings usually includes the following steps:
1. Graphite powder pretreatment: Select the appropriate graphite powder and purify it to remove impurities.
2. Graphite molding: The treated graphite powder is pressed through the mold to form the blank of the required shape.
3. Antimony impregnation: special impregnation technology is used to fill the pores in the graphite blank with liquid antimony, and the antimony material is closely combined with graphite through high temperature sintering.
4. Machining: The sintered composite material is machined to meet the exact size and tolerance requirements.
5. Follow-up treatment: According to the needs of use, the bearing surface treatment, cleaning and lubrication treatment.
7.Impregnated antimony graphite bearing for its unique performance advantages
