Self-lubricating bearings for its unique performance and its economy at home and abroad a wide range of applications. The copper sleeve matrix with high strength and high hardness of copper alloy, copper than the average hardness, strength more than doubled. The surface of the copper sleeve embedded inlaid graphite-based oil-containing solid lubricants, lubrication area of about 25%, bearing the operation of their own to produce a layer of solid - liquid mixed lubricating film, play to reduce the friction effect, greatly enhance the copper sleeve Its performance. It can work normally under severe conditions such as heavy load, high temperature, impact load, reciprocating motion, water and difficult to refuel. While the ordinary copper sleeve due to failure of the oil film wear and tear accelerated or even can not be used. The product has been nearly 10 years of history, has been widely used in various industries across the country. With the understanding of the use of this product will become increasingly large, will produce good benefits to society.
