Graphite Bearing

Advantages of Graphite Bearing: Graphite bearing has excellent self-lubrication,Good resistance to chemical corrosion,High thermal conductivity and thermal stability,Good abrasion resistance, enough mechanical strength.

Graphite bearings are used in bearing system applications where external lubricants cannot be used due to sanitary reasons, or to prevent the risk of contamination. Bearings are simple parts that are used to reduce friction when placed between two moving parts and are often applied with traditional lubricants to decrease friction. However, there are certain situations when lubricants cannot be used and in these instances,bearings made of graphite are used because they are self-lubricating.

Graphite is naturally a greasy mineral, and does not require any additional fluids to reduce friction when used as a bearing. It also has an extreme temperature resistance, more than any metal, and is able to maintain its structure and shape even in temperatures up to 5000°F. Therefore, machined graphite is commonly used in high heat environments, where oil, grease and metals tend to oxidize, often in load capacity systems. Using graphite bearings dramatically opens up the temperature and chemical range of mechanical operations; some even fare well in cryogenic conditions as graphite is not susceptible to damage as a result of thermal shock. Mostly, they are used in the food, beverage, medical and pharmaceutical industries in machinery where contamination is a concern. They also exhibit high temperature stability and chemical resistance, and can therefore operate in underwater, outer space, underground, in liquid, gas and vacuum environments.

Graphite bearing is commonly used in industrial machinery such as lubricant parts.The material are divided into metal, nonmetal and composite materials.Graphite bearing is different from metal bearing characteristic, mainly displays in: the lubrication, high temperature resistance, corrosion resistance and light, etc.
