Characteristics of graphite copper bushing
Jul 09, 2018

The graphite copper sleeve is mainly based on the high strength copper alloy as the matrix (also known as the JDB solid inlaid self lubricating bearing). It is used as a lubricant to replace the traditional cupric copper sleeve by the solid lubricating material embedded in the special matrix. It can not be refueling, long term oil shortage or oil free environment, which makes up for the shortage of conventional copper sleeve. It has the characteristics of high bearing capacity, impact resistance, high temperature resistance, strong self lubrication and so on. It is especially suitable for heavy load, low speed, reciprocating or swinging, which are difficult to lubricate and form oil film. Because of its high hardness and strength, and low cost, the service life of the low speed heavy load is twice higher than that of the ordinary copper sleeve, so it is favored by the customers. Different sizes and materials can be customized according to customer requirements.
