Introduction of Bronze Bushings
Bronze bushings are sliding bearing components made of copper-based alloys (such as aluminum bronze and tin bronze) as raw materials. They are made by casting, sintering, rolling and other processes, and are used to reduce friction and wear between mechanical parts and support radial or axial loads.
Since copper alloy has high strength and excellent wear resistance, copper bushings can withstand pressure of 700MPa and have excellent self-lubricating properties. Myway provides bushings in various sizes from micro to large, and the maximum diameter supported for customization is 1200mm.
Thanks to its excellent wear resistance and corrosion resistance, bronze bushings are widely used in aerospace, shipbuilding, steel manufacturing, heavy industry, automobile, new energy and other fields, especially in high-load, low-speed and heavy-load applications and equipment.
Main Types of Bronze Bushings
Plain Bronze Bushings
Made of continuous casting C93200 bearing bronze, Plain Bronze Bushings conform to industry standard sizes and can be customized according to your specific size and tolerance requirements.
Grooved Bronze Bushings
The grooves of bronze bushings can be cut into “Spira-Lube” groove, “National 11” groove, circular, straignt, single loop, double loop, figure 8, double figure 8 and other groove patterns.
Flanged Bronze Bushings
Flanges are annular structures extending from the outer or inner ring of bushing, which greatly enhance the ease of installation and work stability through positioning, securing and bearing.
Wrapped Bronze Bushings
The round or diamond shaped oil pockets on the inner surface are designed for easy lubricant filling. The wrapped bronze bushings are suitable for low-speed, high-load applications.
Sintered Bronze Bushings
Sintered bronze bushings are made by sintering process under high temperature and high pressure conditions. Its porosity is from 30% to 40% and can be lubricated by oil or grease.
Cast Bronze Bushings
Bronze bushings made by centrifugal casting process, with dense internal organization and excellent wear and corrosion resistance, are suitable for use in crushers of mining machinery.
Solid Bronze Bushings
Made from the copper alloy with copper content of more than 85%, Myway solid bronze bushings perform well in harsh environments and are unaffected by impurities.
Oil Impregnated Bronze Bushings
After powder metallurgical process, the bronze bushings have evenly distributed voids, then filled with lubricant, making them self-lubricating and eliminating the need for frequent maintenance.
Graphite Impregnated Bronze Bushings
Solid graphite with lubricating effect is filled into the pre-dug circular holes on the plain bronze bushings, giving them strong load carrying capacity and self-lubricating performance.
Bronze Bushings Types by Material
Nickel Aluminum Bronze Bushings
Common nickel-aluminum bronze alloys used to make bushings are AMS 4640 C63000, AMS 4590 C63020, AMS 4880 C95510, etc. They have high strength, ductility and wear resistance.
Aluminum Bronze Bushings
Aluminum bronze alloys such as C85200, C95300, C95400, C95500, C95600 are available for selection. They have high strength and hardness, with tensile strength greater than 600 MPa.
PTFE Fiber Steel Bronze Bushings
PTFE fiber steel bronze bushings, also called sf-1 bushings, including steel backing, sintered bronze powder layer and PTFE lubrication layer, with low coefficient of friction and good properties.
Bronze Bushings by Size
Large Bronze Bushings
Specialized for heavy equipment applications like construction equipment, hydroelectric power, crushers, offshore vessels, etc., large bronze bushings are available up to 20 inches in diameter.
Small Bronze Bushings
The inside diameter of miniature bronze bushings is typically less than 2 inches. They are commonly used for precision machinery or small equipment, with excellent strength and wear resistance.
Thin Wall Bronze Bushings
The preferred material for thin walled bronze bushings is aluminum bronze with high strength and low density of 7.45 g/cm³. The bushings have a wall thickness of less than 2 mm.
Features of Productions
Quality Materials
The aluminum bronze series used by Myway has 3-5% nickel added, such as C95400, which increases its corrosion resistance to 1.5 times that of traditional aluminum bronze.
Innovative Design
By continuously improving and innovating the design of bronze bushings, our bushings have excellent oil conduction efficiency, compressive strength, wear resistance, etc.
Advanced Technology
Myway performs surface treatment processes like copper plating, nickel plating, and electrolytic polishing on bronze bushings to improve their corrosion resistance and other properties.
Strict Testings
In order to ensure the quality, performance and service life of bushings, Myway will conduct a series of tests on them, including spectral analysis, hardness test, friction coefficient test, etc.
High Adaptability
The temperature resistance of Myway bushings ranges from -40℃ to 400℃. In addition, its chemical resistance enables it to perform well in harsh environments.
Customization
No matter what material, structure or size of bronze bushing you need, Myway can design it according to your needs and quickly put it into production and deliver it.
Brass Bushings vs. Bronze Bushings
Bronze and brass are both copper alloys and are commonly used raw materials for bushings. However, their composition and characteristics are different. The following is a comparison between the two. You can choose the material that suits you according to your needs.
- Composition: Bronze is a copper alloy that usually contains tin, aluminum or other metal elements. Brass is an alloy of copper and zinc.
- Hardness: In comparison, bronze bushings have higher strength and hardness, while brass bushings are softer and easier to process and install.
- Corrosion Resistance: Brass bushings are often used for general purposes, such as mildly corrosive environments in non-marine applications; while bronze is suitable for harsh environments, including marine, chemical or high-temperature applications.
Economic Cost: Brass bushings are usually cheaper than bronze bushings and are an economical and effective choice.
How to Install Bronze Bushings
Strictly comply with the process specifications and correctly install or move the bronze bushing to ensure the reliability and service life of your equipment to the maximum.
- Preparation: First, you need to confirm that the interference between the outer diameter of the bushing and the inner diameter of the mounting hole is 0.04~0.10mm, grind burrs to Ra≤6μm, align oil holes, and ready tools/grease.
- Core Steps of Installation: If your interference is ≤0.08mm, you can apply grease and press vertically and slowly; however, if the interference is greater than 0.08mm or it is a high-precision scene, you need to heat the mounting hole to 80~120℃ to expand it by 0.05~0.10mm and then install the bushing, or cool the bushing to shrink its outer diameter by 0.03~0.06mm and then install it quickly.
- Inspection: Measure coaxiality (≤02mm), run no-load 15-30 mins (monitor temp rise≤20℃/noise), then test 50%-75%-100% loads (1hr each, check temp/vibration every 15 mins).

FAQs
Yes, bronze bushings require grease during installation and use.
When installing, you need to apply grease evenly to the outer surface of the bushing to reduce friction, facilitate press-in and avoid damage.
In operation, grease reduces wear, prevents corrosion, and improves sliding properties to extend bushing life.
There are the best oil for bronze bushings:
- Lithium Grease: Suitable for scenarios with operating temperatures ≤80℃, it has anti-aging properties and is the first choice for bronze bushings.
- Silicon Grease: better performance in high temperature environment (>80°C), can maintain stability and reduce volatilization.
- Graphite or White Lithium Grease: Commonly used in low to medium speed applications likeautomotive and industrial machinery, providing lubrication protection under high loads.
Note: Greases containing molybdenum disulfide (MoS2) may not be compatible with bronze materials and should be avoided.
- Industrial Machinery: gearboxes, pumps, bearing housings and other low-speed, high-load components.
- Automotive and Agricultural equipment: suspension systems, drive shafts, mechanical joints for tractors and harvesters.
- Marine & Food Processing: Marine components resistant to seawater corrosion, and food grade oiled bronze bushings.
- Aerospace: precision components for high temperature, high load environments such as landing gear and engine components.
