Graphite copper bushings have the following advantages over other copper bushings:
Good self-lubricating performance
Graphite copper bushing in the work, graphite particles will form a stable solid lubrication diaphragm on the friction surface of the shaft and bearings, without the need to add additional lubricant, can be in the case of no oil, less oil normal operation, reducing the workload and cost of equipment maintenance .
For example, in some parts of the equipment that are difficult to be lubricated manually, such as the expansion joints of large bridges and the joints of cranes working at high altitude, the use of graphite copper bushing eliminates the need to build complex refueling devices and reduces the difficulty of maintenance.
Strong wear resistance
Graphite itself has good abrasion resistance, and after combining with the copper alloy matrix, it further improves the abrasion resistance of the material, which is able to operate stably for a long time under the working conditions of high load and high speed, reduce the wear and tear of the parts, and prolong the service life of the equipment.
For example, in the crusher, ball mill and other equipment of mining machinery, graphite copper bushings can withstand the strong impact and abrasion of ore particles, maintain good working performance, compared with ordinary copper bushings, its service life can be greatly increased.
High load bearing capacity
Copper alloy matrix for graphite copper bushing provides high mechanical strength and load-bearing capacity, so that it can withstand large radial and axial forces, suitable for heavy-duty applications.
Like the metallurgical industry rolling mill, continuous casting machine and other equipment, in the process of rolling steel and casting billets, graphite copper bushing can stably support and guide the rolls, crystallizers and other components to ensure the normal operation of the equipment.

Adapt to harsh environment
Graphite copper bushing has good performance of high temperature resistance, not easy to soften or deformation in high temperature environment, can maintain its structure and performance stability, can be used in high temperature, high humidity, vacuum and other harsh conditions.
For example, in the turbocharging system of automobile engine, graphite copper sleeve can withstand the impact of high temperature exhaust gas and erosion, to ensure the normal operation of the turbocharger; in the chemical production of some high-temperature reaction kettle, distillation tower and other equipment shaft sealing parts, graphite copper bushing can also play a good sealing and supporting role.
In addition, graphite copper bushing also has a certain degree of corrosion resistance, can work in some corrosive media in the environment, such as in marine engineering ship propulsion, harbor machinery and other equipment, can resist the corrosion of seawater.
Low friction coefficient
Graphite lubrication can effectively reduce the coefficient of friction between the bearing and the shaft, reduce energy loss, improve mechanical efficiency, and reduce the operating energy consumption of the equipment.
For example, in the yaw system and pitch system of wind turbine, the use of graphite copper bushing can make the rotation of the system more flexible and smooth, reduce the energy loss due to friction, and improve the efficiency of power generation.

Easy to install
Graphite copper bushings are usually designed to be easy to install and dismantle, and can be quickly replaced, reducing equipment downtime and improving production efficiency.
For example, in some automated production line conveyor equipment, when the graphite copper bushing is worn and needs to be replaced, the operator can quickly complete the replacement operation, so that the equipment can resume normal operation as soon as possible, reducing the impact on the production schedule.
Good environmental protection
Since there is no need to use lubricating oil, it avoids the pollution caused by the leakage of lubricating oil, and there is no need to recycle the waste oil, which is in line with the requirements of environmental protection.
In the food processing, pharmaceutical and other industries that require high environmental hygiene, the use of graphite copper bushings can avoid lubricant contamination of the product to ensure the quality and safety of the product.
Economical
Although the initial cost of graphite bushings may be relatively high, their long service life and low maintenance costs can reduce the overall operating costs of the equipment in the long run.
For example, in some large-scale industrial equipment that runs continuously for a long period of time, the use of graphite copper bushings can reduce the number of equipment downtimes and maintenance costs, and improve the reliability and economy of the equipment.
