What are the applications of graphite bushings flange bearing bronze?

You can use flange bearing bronze graphite bushings in different fields, such as Mining industry

Long conveyors are often used in mines to transfer recovered ore and other items from the depths of the mine to the mine exit.

These conveyors are often located in inaccessible areas, making constant lubrication and routine maintenance of the conveyor’s bearings a challenge.

The flange bearing bronze graphite bushing eliminates the need for lubrication, allowing for longer maintenance intervals and less frictional resistance at the bushing interface.

Treatment of Metals

Heat treatment of metals is a necessary procedure in various sectors, from automotive manufacturing to industrial tool making.

This method involves heating metals at extremely high temperatures to change physical qualities such as hardness, strength and toughness.

Heat treatment furnaces will often use flange bearing bronze graphite bushings, whether in batch or continuous operation.

The oil or grease lubrication required to lubricate conventional roller bushings will burn out at high temperatures.

Power Plants for Coal

Electrostatic precipitators are used in coal power plants to collect suspended dust particles from the air using huge charged plates.

This dust is collected and transported to a drag-out conveyor where it is properly disposed of.

flange bearing bronze graphite bushings are commonly used in drag-out conveyors due to their wear resistance and long working life.

Graphite Bearings for Industrial Applications

Industrial applications of graphite bearings

Textile industry

The dyeing of textiles is achieved by pulling the fabric through its length.

In these machines, there is often a need for bushings that can run completely submerged in the dye and resist the chemical corrosion of the dye chemicals.

For this reason, industrialists prefer graphite bushings from Bushing MFG.

Graphite is an inert material that can operate in the most corrosive conditions, from caustic acids to strong bases. It can also operate fully submerged in a variety of fluids.

For these reasons, graphite bushing assemblies are common in textile dyeing facilities.

Nuclear Power Plants

High temperature dampers in nuclear power plants redirect the airflow as needed throughout the facility.

These dampers rely on bushings that are not only resistant to extreme temperatures, but also require no maintenance.

The flange bearing bronze graphite bushing meets both of these criteria, which is why it is widely used in nuclear power reactors around the world.

Oil-free Graphite Bearings and Flange Bronze Graphite bushings can break down over time due to friction between the graphite bushing and the rotating shaft it supports. When designing a bushing system, the emphasis is on damage resistance, which is the key to minimizing bushing damage caused by friction. You can improve the performance of your bushings, and by following certain precautions, you can minimize the frequency of maintenance required. The damage rate of graphite is highly application specific due to the numerous variables that can affect wear, such as load, speed, presence of abrasives, etc. This means that there are many factors to consider when it comes to maximizing wear resistance. Custom graphite flange bronze bearing bushings are resistant to damage. However, you must be aware of the points listed above to avoid risk. What should I consider when purchasing flange bronze bearing graphite bushings? Before purchasing flange bronze bearing graphite bushings, you must check against the following list Make sure you are going with a genuine manufacturer. See if your flange bronze bearing graphite bushing is original Ask someone nearby about the company you are going to Check the seal or product code on the flange bronze bearing graphite bushing to make sure it is not fraudulent. Visit the job site in person to satisfy you that you are investing your money in the right place. We meet all of these requirements. We have multiple lines for manufacturing flange bronze bearing graphite bushings. Whether you need flange bronze bearing graphite self-lubricating bushings or any other help, we’re here to help you. How do I replace flange bronze bearing and graphite bushings? The job of a bushing is to support a rotating shaft. As a result, there will undoubtedly be some friction and damage during operation. Regardless of their type, bushings are often one of the first parts of an application to require replacement. These bearings are not prone to galling or seizing, which is a recognized failure mode for other types of bushings. This is because there is no metal attraction between the graphite and the shaft. Because graphite is self-lubricating, it can run dry in some cases without the need for grease or oil. Heat and chemical resistance are also essential features of flange bronze bearing graphite bushings when pumping hot fluids or corrosive chemicals. Graphite bushing flange bronze bearing installation process Here is how you install your flange bronze bearing graphite bushing. Your flange bronze bearing graphite bushing must be treated with care during the installation process. Most flange bronze bearing graphite bearings are press-fitted to the housing, although in some cases another mounting method may be required. It is also critical to utilize proper interference. During mounting, heat the bearing housing to reduce interference and make it easier to press the bushings together to achieve a tight interference fit. To further eliminate interference, flange bronze bearing graphite bushings can be cooled with liquid nitrogen to achieve a tight interference fit. Leading chamfers on the bearing OD and housing ID help guide the bearing into place. Press-fit the bearing in a single motion at a steady rate. Machining of the bushings after press-fitting is critical to account for any problems that occur during installation due to press-fitting. This pre-inspection helps to build the bushing to suit the application. Remember that you must maintain adequate running clearance between the shaft and bushing. For most subsea applications, this running clearance should be 0.1% to 0.3% of the shaft diameter. It provides enough room for the hydrodynamic layer to form while avoiding excess space that could produce rattling or increase localized wear. Once the flange bronze bearing and graphite bushing has been pressed down and to the exact size, the flange bronze bearing graphite bushing replacement is complete. What materials are used to make flange bronze bearing graphite bushings? We use the following materials to make flange bronze bearing graphite bushings. The high strength, hardness and wear resistance of carbon combined with the natural lubricity of graphite in a carbon/graphite compound to make graphite bushings. These chemically bonded carbon compounds are strong, thermally stable, and chemically and corrosion inert in most applications. When more incredible wear performance, higher temperatures or impervious materials are required, impregnation with resins, metals and oxidation inhibitors can improve performance properties. The process of assembling carbon into a metal housing is determined by the carbon grade, metal type and operating temperature. Crimping is typically used for low temperature applications where only a small amount of interference is required to inhibit the carbon from rotating on its own. For high temperature applications where more interference is required to avoid carbon rotation, shrink joints are used. During the shrink fitting process, the carbon is dropped into a hot metal housing. As the metal cools, the shell shrinks and catches the carbon. In this way, custom-sized flange bronze bearing graphite plugged bushings are made by using practical and straightforward materials and processes. We can also provide you with a detailed video for a better understanding. What is the difference between regular bushings and graphite bushings? Graphite flange bronze bearing bushings have several advantages over other bearing materials. This is illustrated by the fact that flange bronze bearing graphite bearings are used in a variety of industries, from food production to wastewater control. While the applications of these bushings vary greatly, wear resistance is a key feature of all of them.

When manufacturing graphite bushings flange bronze bearings, the correct grade selection is critical and it is important to pay attention to this issue.

There are hundreds of different graphite grades on the market, each with its own advantages and disadvantages.

There are many factors that must be addressed when deciding on the best graphite grade.

• Whether the application is wet or dry.
• What is the temperature where you are working?
• What are the loads and speeds involved?
• Are there any corrosive chemicals in the area?
• What is the maximum amount of wear that a bearing can tolerate?

Whether the application is wet or dry.

What is the temperature where you are working?

What are the loads and speeds involved?

Are there any corrosive chemicals in the area?

What is the maximum amount of wear that a bearing can tolerate?

Finally, contacting your graphite manufacturer directly is the best way to confirm that you are using the correct grade for your application.

Choosing the Right Shaft Material: The choice of shaft material can have as much effect on bushing flange bronze bearing damage as the graphite grade.

The shaft must be as hard and smooth as possible. A more demanding shaft will maintain its surface finish for a longer period of time than a softer shaft.

Maintaining a smooth surface of the shaft throughout its service life will greatly reduce wear, which is why only carbon will wear during operation.

Corrosion resistance must also be adequate to avoid rust or pitting, which can reduce the finish.

Use Abrasives Carefully, Abrasives can be very destructive to graphite bushings.

Abrasives can easily scrape the graphite surface, greatly accelerating the rate of damage. If abrasives are used in your application, you can take the following steps to reduce their impact A groove in the bushing flange bronze bearing bore can be used to “flush away” as much of the abrasive material as possible.

Fluids introduced into the working clearance of the bearing can help reduce damaging contact between the bearing and the abrasive particles.

You can combat the harmful effects of abrasive buildup by diluting the concentration of abrasive and draining it from the operating gap.

Fluid Lubrication: Liquid in the running clearance of a graphite bushing flange bronze bearing can almost prevent the deterioration of the bushing flange bronze bearing.

If sufficient fluid is available, impermeable graphite bearings can maintain a hydrodynamic layer that acts as a barrier between the bearing and the shaft.

This allows the graphite bushing flange bronze bearing to maintain a much higher PV value compared to dry operation.

In other cases, submerged bushing flange bronze bearings can tolerate PV values up to 75 times higher than in dry operation.

Even if the bushing flange bronze bearing is not fully submerged in fluid, splash, steam or intermittent lubrication can help reduce wear significantly.

Mitigating PV: Bushing flange bronze bearing damage is the result of load and sliding speed. pV can be used to reduce this damage.

Graphite bearings can usually withstand continuous exposure to PV of about 30k psi/min under dry operating conditions.

Increasing the weight distribution of the area is one of the easiest ways to minimize the PV value of the application.
