Advantages of graphite inserts for metal bushings
Published on 6/9/2020· Updated on 7/22/2026
The bronze bushings and the porosities they have, are made so that they can be in contact with the graphite and in turn have the optimum development. With this, it is possible to avoid the wear in the pieces; because it helps the rotation of the shaft in the machines, resisting the impact and the corrosion that this generates.
5 advantages of graphite bronze bushings
- They have a long service life
- Less wear and tear and gives you an option to generate maintenance safely.
- The material has porosity that facilitates lubrication.
- The delivery of the product is faster
- It has almost final measurements and very little material is wasted when the part is finished.
It is important to mention that graphite bronze bushings, are bushings that are naturally lubricated by graphite and are therefore known as graphite grafted bronze bushings. They are also helped by bronze bearings, as they are stronger and have a longer life. Because of the graphite, they have longer life despite wear and corrosion.
Depending on the type of needs, graphite carbon bushings are also used, which are self-lubricating and are made according to the needs. In addition, depending on the chemical with which it comes in contact, its characteristics will also be determined.
Applications of bushings.
It has two applications, which are:
Dry application.
It is used to work with temperatures that are high and low, also the graphite bushings have oil or water based lubrication if used in high temperatures. This allows the parts not to deform. When used at low temperatures, it avoids friction and excessive wear in the process.
Submersible applications.
It is used when submerged in liquids or chemicals so that the elements do not combine; and to avoid that by the chemicals some type of corrosion is generated, graphite is the best option.
Graphitized bearing uses.
The graphite metal bearings have the highest quality, also add graphite in the holes to give lubrication while working the piece, to withstand the highest temperatures. They are used in processes such as:
- Dry
- Oil lubrication
- Water lubrication
- Fluid lubrication
It is important to mention that these bearings, without graphite, would not have the necessary lubrication to be able to perform a correct operation in the bronze bushings that are in the machines. Machines where these buschings are used include: furnaces; presses; chemical plants; hydroelectric plants, among many others.
Conclusions.
To conclude, the bronze bushings and the porosities they have, are made so that they can be in contact with the graphite and at the same time have the optimum development. With this, it is possible to avoid wear in the parts; because it helps the rotation of the shaft in the machines, resisting the impact and corrosion that this generates.

Limitations to consider
Performance depends on graphite grade, grain orientation, temperature, load, pressure, speed, and operating environment. Material selection should be confirmed for your actual process conditions.
