Graphite Bronze Bushing Bearing Design | Size & Material

Are you tired of constantly replacing your worn-out bushings? Look no further than our Graphite Bronze Bushing Design!

Our graphite bearing is Made with high-quality bronze alloy material with inserted graphite, they are designed to last longer and withstand heavy use. Grooves may be added to feed lubricant to load-bearing surfaces in boundary-lubricated bearings. Design variables are material, lubricant, and bearing size. Lubricant and material determine the load limit. Size is based on keeping within the lubricant/material limitations.

This bushing design is perfect for industrial and heavy-duty applications with its excellent wear resistance and low friction properties. Say goodbye to frequent replacements and hello to long-lasting durability with our Graphite Bronze Bushing Design.

How Do Oil-Free Graphite Bronze Bushings Work?

If you’re looking for a high-performance solution for your industrial applications, oil-free graphite bronze bushings are the ultimate choice.

The oil-free bushing is typically made of a bronze alloy, which provides high strength and durability, while the graphite and other solid lubricants are embedded within the material. When the shaft rotates within the bushing, the solid lubricants are slowly released onto the surface, creating a thin film that helps to reduce friction and wear.

One of the key benefits of oil-free graphite bronze bushings is that they do not require external lubrication, which can be a significant advantage in applications where external lubrication is difficult or impossible to provide.

Application Of Oilless Graphite Bronze Bushing

Oilless graphite bronze bushing is widely used in a metallurgical continuous casting machine, train support, rolling equipment, mining machinery, ships, and steam turbines, such as high temperature, high load, low-speed heavy load occasion use; in low load, high temperature, medium speed and other occasions, such as fireplace door, oven raceway, rubber machinery, light industry machinery, machine tool industry; its end face can be used with the substrate welding installation, so it is suitable for metallurgical machinery, construction machinery, oil transmission Machinery and other areas that can not be refueled; in the lifting machinery support parts are particularly adapted, such as winch support, crane support, excavator support.

Bearing Design Considerations | Self-Lubricating Graphite Bronze Bushing

When designing a self-lubricating graphite bronze bushing, there are several important considerations to keep in mind:

  • Load capacity: The bushing must be able to withstand the loads it will be subjected to without deforming or failing. This depends on the material properties and the geometry of the bushing.

  • Friction and wear: The bushing should be designed to minimize friction and wear. The graphite in the bushing provides self-lubrication, but the design should also take into account the operating conditions and the mating surface.

  • Temperature and environment: The bushing should be able to operate in the intended temperature and environmental conditions without degrading or failing. The graphite in the bushing can be affected by high temperatures, so the design should consider this and other environmental factors.

  • Installation and maintenance and cost

5 Bearing Design For Graphite Bronze Bushing:

  • Graphite Impregnated Bronze Bushings: These bushings are made by adding graphite inserts to the bronze material during casting. They do not require lubrication for a long time and are suitable for high loads. They have a low coefficient of friction and are wear-resistant
  • Plug Graphite Bushing: In this design, solid lubricant graphite-based plugs are incorporated into the bronze material. This results in a self-lubricating bushing that is particularly useful in applications where maintenance poses challenges and conventional grease and oil lubricants may experience burn-off due to elevated temperatures.
  • Chemical Composition Bushings: These bushings are made from high-strength bronze alloys permanently embedded with PTFE solid lubricants. They are suitable for underwater applications and are specified by water power authorities and engineeringOil-Free Flange Graphite Self-Lubricating Bearing: This design uses flange bearings with graphite self-lubricating plugs. They are oil-free and provide a large range of flange bearings and graphite self-lubricating bushings
  • Cast Bronze Bearings: These bearings are made from high-strength bronze alloys with good wear resistance and corrosion resistance. They can be used in a variety of applications, including aerospace, oil & gas, and marine/defense

Advantages Of Graphite Plugged Bronze Bushing

  • The shape of graphite bronze bushings can vary greatly, with characteristics such as flange, ball, and plate being customized to enhance the overall performance of the application.

  • The structural feature of self-lubricating graphite bronze bushing is the use of a certain combination of metal base material and solid lubricant, the performance of the two materials complements each other, which can more comprehensively meet the requirements of graphite bronze bearings for construction machinery.

  • Maintenance free and self-lubricating, friction coefficient is low enough to work under heavy loads.

  • Sizing and reaming capability

  • Space saving and weight reduction of the whole parts

Insert graphite bronze bushin graphite Bearing use load conditions are determined by the product of surface load p and allowable speed v and PV value

Inner Diameter And Width

Increasing the width of graphite bronze bushing can increase the load-carrying capacity and reduce the bearing surface load. However, when the width is increased to a certain value, it may reduce the anti-bias load capacity and cooling effect, and damage the bearing prematurely.

The Thickness Of Self-Lubricating Graphite Bronze Bushings

Considering the thermal expansion, heat conduction, and mechanical strength of the bearing, its thickness only needs to meet the requirements of the machining process.
