Aluminium Bronze Oilless Bearing– a corrosion-resistan t metal in seawater, 2.0966 cual10ni5fe4, cual10ni5fe4 equivalent material, C63000 bronze bushing,

Copper-based alloys with aluminum as the main alloying element are aluminum bronze containing iron and manganese elements, and are high-strength heat-resistant bronze.

Marine applications place high demands on their materials. The high salinity of seawater and ocean currents are just two of the many factors that promote corrosion. However, there is an alloy that can withstand the harsh conditions of the ocean.

Corrosion is a nasty partner in the industry. Accordingly, the expectations for materials are high. They must be of high quality bronze oilless parts, as durable and corrosion-resistant as possible – and all at the unbeatable possible cost. However, it is not worthwhile to save on material procurement.

General aluminum bronze, usually containing less than 11.5% aluminum, sometimes with some iron, nickel, manganese and other elements added. Aluminum bronze can be heat treated and strengthened, and has higher strength than tin bronze and better resistance to high temperature oxidation. Aluminum-copper has good strength and wear resistance. Used to manufacture higher strength screws, nuts, copper sleeves, sealing rings, etc., parts and wear resistance, the most outstanding feature of aluminum bronze is its good wear resistance. Aluminum bronze is aluminum bronze containing iron and manganese elements, with high strength and wear resistance, after quenching and tempering can improve the hardness, with good high temperature corrosion resistance and oxidation resistance. Aluminum bronze has good corrosion resistance in the atmosphere, fresh water and seawater, fair cutability, welding is not easy to fiber welding, and good hot pressing processing.

“Advantages of aluminum bronze self-lubricating graphite bronze bushings in corrosive environments”

Especially in the marine industry, corrosion-resistant bushings for metal components are required, as seawater is the most common corrosion trigger and accelerates the corrosion process. The reason for this is the high content of dissolved salts. They ensure that chemical reactions in the ocean are much faster than on land. In addition, the ocean currents in the water promote erosion-corrosion and cavitation.

Aluminum bronze self-lubricating graphite bronze bushings and its advantages in seawater

One alloy that is particularly resistant to seawater and is often very corrosion resistant is the aluminum bronze alloy bearing. Aluminum bronze alloys consist primarily of copper with 9-14% aluminum added to it. Other metals such as iron, manganese and nickel can be used as additional alloying elements to further enhance certain capabilities, such as sliding properties.

The excellent corrosion resistance of aluminum bronze self-lubricating graphite bronze bushings is attributed to its passive protective film. Compared to other metals, this film forms very quickly and heals quickly in case of injury. This protective layer manifests itself in its typical brown color. Although this is not aesthetically pleasing, the film protects the metal it surrounds. Aluminum is the main reason for the formation of this film. It reacts easily with oxygen in the environment, forming this impenetrable barrier. Because of these properties, this material is especially used in the marine industry.

Although this external protective film does not give a good impression aesthetically, it is not worth cleaning aluminum bronze. This is because the alloy loses its corrosion resistance in a short time and chemical reactions can cause damage to the aluminum bronze, which may then limit its functionality. Therefore, aluminum bronze self-lubricating graphite bronze bushing self-lubricating properties, bearings do not require special cleaning and maintenance-free.

Multiple uses of aluminum bronze self-lubricating graphite bronze bushing products

Plant components

Due to the seawater resistance of aluminum bronze alloy, it is often used for plant components such as pumps, valves, flanges, pipe fittings, etc. In addition to seawater resistance, the aluminum bronze graphite copper bushing alloy has high strength and hardness, and therefore has good corrosion and erosion resistance. Salt solutions of different concentrations and temperatures do not have a damaging effect on them.

Desalination plants

The lack of fresh water has also led to a strong demand for desalination plants. Here too, aluminum bronze self-lubricating graphite bronze bushings oilless bearing products are used for their corrosion resistance. Seawater or brackish water is also used as cooling water for industrial plants near the coast. Because of its properties,, aluminum bronze alloy is the first choice for self-lubricating bearings in marine industry applications.

Seawater piping systems

As with many aluminum bronze alloys,, aluminum bronze self-lubricating graphite bronze bushings oilless bearing products are particularly useful in propeller and seawater piping systems on ships and offshore platforms. In addition to its resistance to seawater, the, aluminum bronze self-lubricating graphite copper bushing oilless bearing is also insensitive to pitting and crevice corrosion.

What is the oil-free bearing…? No Oil Or Grease, Non ferrous Bushes,  Graphite Impregnated

Oilless Bearings: The Future of Bearing Technology

As industries continue to evolve and innovate, so does the technology behind the machines that drive them. Bearings are an essential component of many industrial machines, providing support and reducing friction between moving parts. Traditional bearings rely on lubrication to reduce friction, but with advancements in material science, a new generation of bearings has emerged: oilless bearings.

What are Oilless Bearings?

Oilless bearings, also known as self-lubricating bearings, are a type of bearing that does not require external lubrication to operate smoothly. Instead, they are made of materials that inherently reduce friction, eliminating the need for additional lubrication. This makes them an ideal choice for machines that operate in harsh environments or where lubrication is difficult or impossible.

Benefits of Oilless Bearings

Oilless bearings offer several advantages over traditional lubricated bearings, including:

1. Reduced Maintenance: Because oilless bearings do not require external lubrication, they require less maintenance than traditional bearings. This can save time and money over the lifespan of a machine.
2. Longer Lifespan: Oilless bearings are designed to last longer than traditional bearings, reducing the frequency of replacements and associated downtime.
3. Increased Durability: Oilless bearings are made of materials that are more durable than traditional bearing materials, allowing them to withstand higher loads and operate in harsher environments.
4. Environmentally Friendly: Oilless bearings eliminate the need for external lubrication, reducing the amount of oil and grease that can leak into the environment.

Applications of Oilless Bearings

Oilless bearings are used in a wide range of industrial applications, including:

1. Food and Beverage: Oilless bearings are commonly used in food and beverage processing equipment because they eliminate the risk of contamination from external lubricants.
2. Medical Equipment: Oilless bearings are ideal for medical equipment because they are self-lubricating and reduce the risk of contamination.
3. Aerospace: Oilless bearings are used in aerospace applications because they are lightweight and durable, making them ideal for high-performance applications.
4. Marine: Oilless bearings are commonly used in marine applications because they can withstand harsh marine environments without the need for external lubrication.

Oilless bearings are a game-changing technology that offers numerous advantages over traditional lubricated bearings. Their inherent friction-reducing properties, combined with increased durability and reduced maintenance, make them an ideal choice for a wide range of industrial applications. As industries continue to evolve, it’s clear that oilless bearings will play a crucial role in shaping the future of bearing technology.

Bronze Sliding Bearing With Solid Lubricant Insert and Flange Bushing
Graphite is one of the three isomers of the chemical element carbon; the other two are diamond and amorphous carbon. Graphite crystallizes in a hexagonal system. Carbon atoms are tightly bound together in the form of flakes. Due to the weak bonding between the flakes, graphite shows a low shear strength under friction. Therefore, it can be used as a solid lubricant and has become one of the traditional and main solid lubricating materials.
