Aluminum Bronze Bearing

Aluminum bronze bearings are a type of copper sleeve produced using composite material technology, typically consisting of a metal substrate (such as steel, bronze, or brass) combined with solid lubricants (graphite, MoS2, etc.). This type of bearing has self-lubricating characteristics and can operate stably under heavy loads, low speeds, or swinging conditions without the need for external oil supply. Its structure includes steel based copper plastic three-layer composite materials, bimetallic inlay, copper based solid inlay and other forms, suitable for wear-resistant components in metallurgical machinery, engineering equipment, hydraulic gates and other fields. It has also been applied in wind power project sliding bearings and other fields, as well as in engineering construction machinery, plastic rubber machinery, automotive parts and other fields

 

 

 

Aluminum bronze is a family of copper-aluminum alloys widely considered the premier choice for high-strength, corrosion-resistant bearings. It is selected for applications where conventional bronzes would fail due to extreme loads, abrasive wear, or corrosive chemical attack.

Here is a technical summary of the normal aluminum bronze bearing alloys we supplied to our customer:

Alloy (UNS)	Key Features	Mechanical Strength (Tensile / Yield)	Hardness (Brinell)	Max Operating Temp	Typical Applications
C95400	Industry standard, high strength, abrasion resistant, "Green" alloy (lead-free)	85-95 ksi / 32-45 ksi	170-195	750°F (1200°F intermittent)	Heavy earth moving equipment, roll neck bearings, machine tools
C95500	Nickel aluminum bronze; superior corrosion resistance and higher strength than C95400	95-110 ksi / 42-62 ksi	195-230	750°F (1200°F intermittent)	High-load, corrosive environments requiring maximum durability
C95200	Standard aluminum bronze with good as-cast properties, often used for heavy-loaded bearings	-	-	-	General heavy-duty bearings, bushings
AMPCOM4	High-performance alloy with uniform gamma-2 phase distribution; exceptional wear and heat resistance	Exceeds standard nickel aluminum bronzes	-	Elevated temperatures	Aircraft landing gear bearings, tube bending dies, gear wheels

Aluminum bronze bearings have good load-bearing capacity. Its material properties enable it to withstand certain pressures and loads, playing an important role in many mechanical equipment.

Under normal working conditions, aluminum bronze bearings can provide stable support for equipment and ensure smooth operation. Its carrying capacity is related to specific application scenarios, working conditions, and other factors. For example, under reasonable rotational speed and lubrication conditions, it can effectively carry the corresponding weight and pressure brought by power transmission.

Its service life is also quite considerable. Through good manufacturing processes and appropriate maintenance, aluminum bronze bearings can maintain stable performance over a relatively long period of time. Regular inspections, appropriate lubrication, and measures to avoid excessive wear can all help extend its service life. However, the actual service life will be affected by various factors, such as the temperature, humidity, and corrosive substances in the working environment. Overall, as long as used and maintained correctly, aluminum bronze bearings can provide reliable support for the normal operation of equipment for a considerable period of time, making them a cost-effective bearing choice.

 

 

Aluminum bronze bearings, as a high-performance sliding bearing solution, involve multiple key steps and precise operations in their production process. The production process of aluminum bronze sleeve bearings, from material preparation, casting, heat treatment, mechanical processing to final inspection, fully demonstrates the precision and rigor of its production process.

Firstly, material preparation is the first step in producing aluminum bronze bearings. This alloy is composed of elements such as copper, aluminum, nickel, and iron, and its composition ratio is accurately calculated to ensure that the final product has excellent mechanical properties and corrosion resistance. During the preparation process, raw materials need to undergo strict screening and inspection to ensure compliance with production requirements. At the same time, according to production needs, raw materials also need to be pre treated, such as cutting, cleaning, etc., for subsequent casting operations.

The next step is the casting process. Aluminum bronze bearings adopt precision casting technology to ensure that the product has a uniform organizational structure and high density. In the casting process, it is necessary to strictly control parameters such as melting temperature, casting speed, and cooling rate to obtain ideal crystal structure and mechanical properties. In addition, the design and manufacturing of casting molds are also crucial, as they determine the shape and dimensional accuracy of the product.

After casting, the product needs to undergo heat treatment. The key steps for the performance of aluminum bronze bearings. By quenching and tempering processes, the hardness and strength of materials can be improved while maintaining their good toughness and corrosion resistance. During the heat treatment process, it is necessary to precisely control the heating temperature, holding time, and cooling method to achieve the best performance improvement effect.

After the heat treatment is completed, the product enters the mechanical processing stage. Aluminum bronze has good processing performance and can be processed into complex parts and components through mechanical methods such as turning, milling, and drilling. In the process of mechanical processing, it is necessary to select appropriate cutting tools and process parameters to ensure the dimensional accuracy and surface quality of the product. At the same time, it is necessary to clean and repair defects such as burrs and burrs generated during the processing.

Finally, products that have undergone mechanical processing require strict inspection and testing. This includes visual inspection and measurement of the size, shape, and surface quality of the product, as well as evaluation of its mechanical properties through methods such as tensile testing and hardness testing. Only products that meet the prescribed standards can be recognized as qualified aluminum bronze sleeve bearings.

In addition to the main steps mentioned above, there are also some details that need to be paid attention to during the production process of aluminum bronze sleeve bearings. For example, in the casting process, it is necessary to prevent the occurrence of defects such as porosity and slag inclusion; During the heat treatment process, it is necessary to avoid overheating or undercooling of the material; During the mechanical processing, it is necessary to maintain the cleanliness and accuracy of the equipment.
