C95400 Aluminum Bronze Bearings

C95400 Aluminum Bronze, commonly referred to as C954, is a high-strength alloy with a primary composition of copper and aluminum, and additional elements like iron and nickel to enhance its strength. It is renowned for its excellent resistance to wear, fatigue, and deformation under shock or overload conditions. This makes it an ideal material for heavy-duty applications, including bearings. Bronze Bearings Compliance and Standards: C95400 Aluminum Bronze meets various standards and compliances, ensuring its suitability for use in different industries and applications:

  • Standards: ASTM B-148, ASTM B-271, ASTM B-505, ASTM B-763, SAE 461, SAE J461, SAE J462, SAE 68A, AMS 4870, AMS 4871, AMS 4635

Bronze bearings that are self-lubricating often contain small pockets or grooves filled with solid lubricants like graphite. These types of bearings are designed to operate with little or no external lubrication because they have this feature.

Here’s how it works:

  1. The graphite is embedded in the bronze material that makes up the bearing. This is typically done during the manufacturing process. The graphite might be in the form of small pellets or particles, or it might be in the form of thin lines or grooves.
  2. When the bearing is in use, the heat and friction generated by the moving parts cause the graphite to release a small amount of lubricant. This lubricant then coats the moving parts, reducing friction and wear.
  3. Over time, as the bearing continues to operate, more graphite is gradually released. This means that the bearing can continue to lubricate itself even over long periods of operation.
  4. The lubrication provided by the graphite reduces the need for additional lubrication. This can make these bearings a good choice for applications where regular maintenance is difficult or impossible.
  5. Because the lubrication is provided by solid particles rather than a liquid or gel, these bearings can also be a good choice for applications where contamination or leakage of lubricant could be a problem.

The use of graphite in bronze bearings is a clever engineering solution that can increase the lifespan of the bearing and reduce the need for maintenance. It’s an example of how materials science can be applied to solve practical problems in mechanical engineering.

Solid-lubricant-inlaid bronze bearings are high-performance solid lubricating products that embed graphite or MoS2 solid lubricants in a self-lubricating, wear-resistant bronze base. This design breaks through the limitations of ordinary bearings that rely on oil film lubrication.

During use, the friction heat causes the solid lubricant to rub against the shaft, creating excellent conditions for co-existing oil and powder lubrication. This not only protects the shaft from wear but also ensures the eternal characteristics of solid lubrication. Its hardness is twice that of ordinary copper sleeves, and its wear resistance is also twice as high.

Currently, these bearings are widely used in continuous casting machines for metal processing, injection molding machines, train brackets, steel rolling equipment, mining machinery, ships, gas turbines, and other situations involving high temperatures, high loads, and low-speed heavy-duty applications.

Alloy: C95400 Aluminum Bronze bearings bushings

Aluminum Bronze C95400 is a copper base alloy with aluminum as the main alloy element. It is an aluminum bronze containing elements of iron and manganese and belongs to high-strength heat-resistant bronze. The aluminum content usually does not exceed 11.5%, and sometimes the corresponding iron, nickel, manganese, and other elements are added to further improve the characteristics. strengthen by heat treatment. Its strength is higher than that of tin bronze, and its resistance to high-temperature oxidation is also better.

Aluminum bronze has many excellent properties. For example, with high strength, hardness and wear resistance, commonly used to make gear blank, thread, and other parts. It also has good corrosion resistance, so it can be used to make corrosion-resistant parts, such as propeller, valve, etc.C95400 does not generate sparks under impact and can be used to make sparkless tool materials.

Also has good thermal conductivity and stable stiffness, so as a die material in the drawing, rolling stainless steel plate heat exchanger will not produce sticky mold, scratch workpiece advantages, has become a new type of die material.

Aluminum bronze has a shape memory effect and has been developed as a shape memory alloy. The price is relatively cheap, which makes it a partial substitute for some expensive metal materials, such as tin bronze, stainless steel, nickel base alloy, etc. It is because of its excellent characteristics that aluminum bronze is becoming more and more popular and plays an important role in the civil industries.

How does It work?

When the mutual friction occurs between two non-lubricated surfaces, the two contracts with the uneven surface of the peak by the shear, stick-slip
and plastic deformation giving rise to friction and wear. Conventional lubricants can significantly reduce these effects, however, the conventional
lubricant will be more and more squeezed out of the contact area with an increasing surface which formed the dry friction or boundary lubrication.
With Aluminum Bronze bearings bushings, the lubrication is effected by the sliding material itself, The solid lubricant is released from the friction
material by micro-movement. This gives the sliding partners smooth surfaces with a firmly adhesive solid lubricant film, the solid lubricant film
remains within the contact area even under heavy loads. The embedded solid lubricant plugs can be continuously provided to the friction surface
to reduce friction resistance and wear, thus make the bearing can be worked under low wear rate and long-life service.

These are a type of bearings that integrate solid lubricants like graphite or molybdenum disulfide (MoS2) within a bronze base that is both self-lubricating and wear-resistant.

The design of these bearings marks a significant departure from the conventional bearings that depend on oil film for lubrication. As these bearings function, friction heat induces the solid lubricant to interact with the shaft. This interaction results in a unique lubrication scenario with the coexistence of oil and powder, offering superior protection against shaft wear and maintaining the inherent properties of solid lubrication indefinitely.

Additionally, these bearings exhibit twice the hardness and wear resistance of standard copper sleeves. They are extensively utilized in various high-demand applications, including but not limited to, continuous casting machines in metalworking, injection molding machines, train undercarriages, steel mill equipment, mining machinery, ships, and gas turbines. These applications often involve high temperature, high load, and low-speed heavy-duty conditions.

Solid lubricated inlay bronze bearings, given their inherent properties and advantages, find use in several applications across various industries. Here are some typical applications:

Cast bronze bearings with solid lubricant are a type of self-lubricating bearing that combines the superior load-bearing capacity of bronze with the low friction properties of solid lubricants.

These bearings are manufactured by casting high-quality bronze alloys as the base material. Then, precise channels or grooves are machined into the bearing surface and filled with a solid lubricant. This lubricant often consists of materials like graphite or molybdenum disulfide, known for their excellent lubrication properties and low friction coefficients.

The solid lubricant is designed to fill the bearing surface and provide a consistent layer of lubrication during operation. As the bearing operates and the shaft moves, the solid lubricant is transferred to the shaft and bearing surface, reducing friction and wear.cast bronze bushing

Key advantages of cast bronze bearings with solid lubricate include:

  1. Self-Lubricating: The solid lubricant provides consistent lubrication, reducing the need for regular maintenance and re-lubrication.
  2. High Load Capacity: The bronze material offers a high load-bearing capacity, making these bearings suitable for heavy-duty applications.
  3. Low Friction: The solid lubricant reduces friction, which can improve equipment efficiency and lifespan.
