C86400 Cast Bronze Bushing

C86400 bronze bushing, also called Manganese Bronze, is a tough alloy known for its strong build and resistance to rust. It’s mainly used in roller bearings because it’s very strong, wears well, and is easy to shape. C86400 is made of copper, zinc, lead, iron, aluminum, and manganese, each in specific amounts. It’s commonly used in many industries like consumer goods, electronics, manufacturing, shipping, and plumbing for things like boat parts, ship fittings, and machine pieces.

Manganese bronze bushings made from C86400 alloy are self-lubricating bearings ideal for tough jobs with heavy loads and slow speeds. They’re often seen in ships and factories because they last long and work reliably. Different kinds of manganese bronze alloys are out there, each with special features that suit different uses. For example, C86300 Manganese Bronze (also known as SAE 430B) doesn’t need heat treatment and is tough and resistant to wear, perfect for jobs that need these qualities.

Advantages of Using C86400 Cast Bronze Bushing

Cost-Effectiveness

Despite its exceptional performance characteristics, C86400 cast bronze bushing offers cost-effectiveness compared to alternative materials such as stainless steel or exotic alloys. Its long service life and minimal maintenance requirements contribute to lower overall ownership costs.

Low Maintenance

C86400 cast bronze bushing requires minimal maintenance, thanks to its self-lubricating properties and resistance to wear and corrosion. Routine inspections and occasional lubrication are usually sufficient to ensure optimal performance and longevity.

Versatility

The versatility of C86400 cast bronze bushing allows it to be used in a wide range of applications across diverse industries. Whether in automotive, aerospace, marine, or industrial settings, this material offers reliable performance and consistent quality.

Manufacturing Process of C86400 Cast Bronze Bushing

The production of C86400 cast bronze bushing typically involves several stages, including casting, machining, and finishing.

Casting

The casting process begins with the melting of the bronze alloy, followed by pouring the molten metal into molds of the desired shape and size. Once cooled and solidified, the castings undergo further processing to remove any imperfections and ensure dimensional accuracy.

Machining

After casting, the rough castings are machined to achieve precise tolerances and surface finishes. CNC machining techniques may be employed to shape the bushings according to specific design requirements, such as bore diameter and concentricity.

Finishing

The final step in the manufacturing process involves finishing the machined bushings to enhance their appearance and performance. This may include surface treatments such as polishing, plating, or coating to improve corrosion resistance and reduce friction.

Comparison with Other Bushing Materials

When choosing a bushing material for a specific application, it’s essential to consider the characteristics and performance of alternative materials. Here’s how C86400 cast bronze bushing compares to some commonly used alternatives:

Steel

While steel bushings offer high strength and stiffness, they may lack the self-lubricating properties and corrosion resistance of bronze. Steel bushings are often used in heavy-duty applications where maximum load capacity is required.

Brass

Brass bushings share some similarities with bronze in terms of corrosion resistance and machinability. However, brass may not offer the same level of durability and load-bearing capacity as bronze, making it more suitable for lighter-duty applications.

Plastic

Plastic bushings are lightweight, cost-effective, and resistant to corrosion and chemicals. However, they may have lower load capacity and temperature limits compared to bronze, making them suitable for less demanding applications or environments.
