Graphite bushes are a type of bearing that are commonly used in a variety of industrial and manufacturing applications. These components are made from a graphite material that provides a unique combination of low friction, high heat resistance, and low wear. These characteristics make graphite bushes an ideal choice for many applications where high temperatures, low friction, and low wear are required.

Graphite bushes are often used in applications where high temperatures and high speeds are present. For example, they can be found in high-speed spindles, motors, and gearboxes. In these applications, the low friction properties of graphite bushes help to reduce the wear and tear on the other components of the system, increasing its overall lifespan and reliability.

In addition to their use in high-speed applications, graphite bushes are also commonly used in applications where heat resistance is a critical factor. For example, they are often used in the manufacturing of heat exchangers, where they are subjected to high temperatures and corrosive environments.

One of the key benefits of graphite bushes is that they are self-lubricating, which means that they do not require external lubricants to function. This reduces the need for frequent maintenance and helps to increase the overall efficiency of the system.

When choosing a graphite bush for your application, it is important to consider a number of factors, including the size and configuration of the bush, the maximum operating temperature and speed, and the type of environment in which the bush will be used. In addition, it is important to choose a reputable supplier that can provide you with high-quality products that meet your specific requirements.

In conclusion, graphite bushes are a versatile and reliable type of bearing that are commonly used in a wide range of industrial and manufacturing applications. With their low friction, high heat resistance, and low wear, they are an ideal choice for many high-temperature, high-speed, and corrosive environments. When choosing a graphite bush for your application, it is important to consider a number of factors and choose a reputable supplier that can provide you with high-quality products that meet your specific requirements.

Since bearings typically receive a lot of frictional resistance and generate heat, lubricants such as oil or grease are used to prevent seizure or abnormal wear that may result from this frictional heat. Non-lubricated bushings do not require lubrication because the bearing body has a lubrication structure that is achieved by a lubricant or embedded solid lubricant or similar in the bearing body. Because they do not require lubricant, lubrication-free bushings are often used in applications such as precision machinery that is difficult to replenish with lubricant and in equipment that has a poor affinity for oil. They also significantly reduce maintenance costs by eliminating the need for periodic lubrication and enabling long-term stable operation. Lubrication-free bushings are available in a variety of shapes and can be used for different applications as needed. Examples include straight pipe bushings, annular bushings, flange bushings and housing bushings.

Bronze is a versatile and commonly used bushing material because it has many alloys and components. Bronze bushings or bronze bearings are hard and strong, as opposed to brass bushings, which are softer and more prone to deformation. As a result, bronze bushings last longer than brass bushings. They resist shock and impact, wear and corrosion. They require external lubrication during installation and operation, and graphite lubricant can be added to reduce friction and wear.

They are more commonly used in low-speed, high-load and heavy-duty industrial applications and machinery for steel manufacturing, food processing, injection molding, automotive machinery, earth-moving machinery, pumps and other industries.

Two common bronze bushing materials and their uses include.

High-tension brass Bushing. Bronze bushings formed using self-lubricating bearing technology. High-tension brass sleeve bearing, the chemical formula is ZCuZn25Al6Fe3Mn3, mechanical properties are different zinc content, mechanical properties are different, pressure processing properties have good plasticity, can withstand hot and cold processing. It can be adapted to high and low speed machinery, high and low temperature machinery, and food grade applications.

High force brass is widely used, and is made into shingles and bushings by casting. The solid lubricated oil-free bearings (referred to as solid lubricant bearings), which are mainly made of high force high strength brass as the substrate and radially embedded with ordered cylindrical polymer fillers as the friction material (generally graphite, molybdenum disulfide, PTFE, oil and other lubricants), are superior mainly because they make Copper alloy and non-metallic wear reducing materials have their own complementary advantages, not only has a high load-bearing capacity, but also break through the general bearing relying on oil film grease lubrication boundary, to achieve oil-free lubrication, embedded solid lubrication easy to form a lubricating film, its friction and wear performance has played a great role in improving the stability and reliability of high cost. Compared with the composite oil-free bearing, it has the advantages of good machinability, high precision, strong load-bearing capacity and good wear resistance. This self-lubricating guide bush guide plate can be used in many fields such as: construction machinery joint parts, such as excavators, mining shovel machine, rotary drilling rig, concrete pump truck, rock drilling machinery, winch, port crane, etc., and metallurgical machinery continuous casting machinery, water conservancy machinery, conveying machinery, rolling mills, blowing machine film blowing machine, injection molding machine crosshead clamping differential, tire curing machine, trailer balance beam, vacuum switch, etc..

Bronze. The most common are tin bronze, aluminum bronze or manganese bronze alloys, which have high corrosion resistance, making them ideal for marine applications.

Popular designs include bronze alloy graphite oil-free bushings, flanged bronze bushings and oil groove bronze bushings.

Graphite plug parts are suitable for any environment where conventional lubricated parts are used. For clean operations, graphite parts are ideal because they do not require liquid lubricants such as grease or oil at all, which can cause contamination of the product. Self-lubricating parts, on the other hand, work well in very dirty environments. Without the presence of grease or oil, there is nothing to attract contaminants to the bearing surface, which translates into a longer service life.

Bronze Bearings Manufacturer，Hard and strong bronze bearings have a long life and resist vibration, shock, wear and corrosion (external lubricants are required to reduce friction and wear during installation and operation).

Graphite provides sufficient lubrication and no additional lubrication is required in all applications. In fact, additional lubrication may impair graphite’s ability to self-lubricate. Liquid lubricants tend to attract dust and grit, leading to premature graphite damage. Grease is a particular problem and graphite parts should not be coated with grease. If these precautions are taken, the life of self-lubricating components is virtually unlimited.

Cast Brass Bronze Bearings with Solid Lubricant Inserts, Self-lubricating graphite brass bearings feature maintenance-free operation and are suitable for complex shapes when high speed operation is required and when used in applications with limited space and variable loads.

In terms of total life cycle cost, self-lubricating parts cost significantly less than conventional parts. Graphite is extremely durable and can provide years of continuous lubrication. No additional lubrication is ever required. The cost of periodic lubrication over many years is avoided, as is the risk of not lubricating and the costs associated with premature failure. Includes wear plates, wear bars, bushings and many other related items.
