Graphite copper bushing

Graphite copper sleeves, also known as copper-graphite bearings, are self-lubricating bearings made of special materials. Different copper-graphite bearings are selected according to different uses and working conditions. One of the major types of solid-embedded copper-graphite bearings (JDB) is a novel lubricating bearing that combines the characteristics of metal bearings and oil-free lubrication bearings. The metal matrix bears the load, and the specially formulated solid lubricating material plays the role of lubrication. It has the characteristics of high bearing capacity, impact resistance, high temperature resistance, and strong self-lubricating ability. It is especially suitable for heavy loads, low speeds, reciprocating or swinging situations where it is difficult to lubricate and form an oil film, and it is not afraid of water wash and other acid erosion. And scour.

graphite copper sleeves generally report that it not only saves oil and energy, but also has a longer working life than ordinary sliding bearings. At present, the products have been widely used in metallurgical continuous casting machines, rolling equipment, mining machinery, ships, steam turbines, water turbines, injection molding machines and equipment production lines.


The graphite copper sleeve and the self-lubricating bearing allow the construction machinery to run quickly, while reducing the use of various materials and enhancing work efficiency. Therefore, for complex equipment such as large machinery, heavy machinery, and construction machinery, graphite copper sleeves and self-lubricating bearings should be used to make the products excellent and high-quality.
