A graphite bearing is a mechanical component used to reduce friction between two moving parts while supporting the load. It’s a type of plain bearing, also known as a bushing, sleeve bearing, or sliding bearing.

Graphite bronze buhing is primarily used in applications that need continual lubrication in hard-to-reach areas. Graphite is mechanically forced into the holes/grooves under extreme pressure. A film of lubricant is transferred to the shaft as it begins to turn. These bearings offer continuous lubrication over long periods without maintenance.

What Is A Graphite Bearing?

Copper base graphite bearing is a metal matrix composite made of a pure copper or copper alloy as a matrix and graphite particles as lubricating components. It has excellent mechanical properties, oxidation resistance, corrosion resistance, and wear resistance.

Self-Lubricating Graphite Bronze Bushings Are Always The Focus Of Attention.

Our graphite bushings also have excellent temperature stability and chemical resistance. This feature allows them to work in various conditions such as underwater, in space, underground, and in liquid, gas, and vacuum.

Why Use Graphite As A Solid Lubricant?

The Perfect Self-Lubricating Solution

Our graphite bearings are the perfect solution for projects that do not easily provide lubrication or where conventional lubricants may carbonize. Oil supply systems are designed to be both time-consuming and costly – using our oil-free bearings can greatly reduce the cost of maintenance and oil supply because it eliminates any need for such systems.

Oilless Graphite Bushings Have Been Developed For High-Load, Low-Speed Applications, They Are Made Of Rotational Cast High-Strength Bronze Busing And Solid Lubricant (Graphite). This results in reduced wear and extended bearing life, especially in applications where high-speed operation or frequent start-stop cycles are common.

Our oilless bearings are graphite loaded and can withstand temperatures of up to 400°C (800F) as well as cryogenic temperatures down to -200°C (-400°F) depending on which material is selected. can withstand extremely high temperatures, making them suitable for applications in harsh environments.

Application Of Graphite Bearing

Automotive Industry

Graphite bearings are widely used in the automotive industry for components such as engine components, transmissions, and suspension systems. Their self-lubricating properties and ability to withstand high temperatures make them an ideal choice for these applications.

Industrial Machinery

In industrial machinery, graphite bearings are used for various applications, including pumps, compressors, and conveyor systems. They offer excellent performance in high-temperature and high-load environments.

Graphite Bronze Bushing vs. Bronze Bearing

Now let’s compare graphite bronze bushings and bronze bearings across several important factors:

  • Both graphite bronze bushings and bronze bearings offer excellent load-carrying capabilities. However, graphite bronze bushings, with their self-lubricating properties and graphite infusion, exhibit superior performance under high-load conditions. The graphite particles act as solid lubricants, reducing friction and enhancing the bearing’s ability to withstand heavy loads.
  • Graphite bronze bushings have inherent self-lubricating properties due to the presence of graphite particles. bronze bearings rely on external lubrication to reduce friction and ensure smooth operation.
  • graphite bronze bushings have good wear resistance due to the self-lubricating graphite particles
  • Graphite bronze bushings require less maintenance compared to bronze bearings

Advantages Of Graphite Bronze Bearings In High-Temperature Environments

Thermal Stability

Bronze has a high melting point (around 950°C), while graphite has an even higher melting point (around 3,650°C). The combination of these materials in a graphite bronze bearing results in excellent thermal stability, making them suitable for use in high-temperature environments.

Self-Lubricating Properties

Graphite bronze bearings contain graphite, which has a low coefficient of friction and inherent lubrication properties. This allows the bearing to self-lubricate without the need for external lubricants, reducing friction and wear. This can be especially beneficial in high-temperature applications where conventional lubricants may break down or evaporate.

Corrosion Resistance

Bronze is naturally resistant to corrosion, making it an ideal material for use in harsh environments where other materials might corrode or degrade. When combined with the chemical resistance of graphite, graphite bronze bearings exhibit excellent resistance to a wide range of corrosive environments.

High Load Capacity

The combination of bronze and graphite results in a bearing with high load-carrying capacity, making it suitable for applications with heavy loads or high stress.

Low Maintenance

Graphite bronze bearings typically require less maintenance compared to other bearing types due to their self-lubricating properties and resistance to wear and corrosion. This can result in reduced downtime and lower operating costs.
