The Lubrication Options Of Solid Bronze Bearings

Solid bronze bushings are vital in machinery, ensuring smooth and efficient operation. Lubrication is essential, with oil and grease being the primary types used. Lubricants serve to enhance sliding properties by reducing friction, prolong the bushing’s lifespan by minimizing wear, and prevent corrosion, despite bronze’s relative corrosion resistance.

Oil is used in specific situations, such as high temperatures, when a thin, fast-circulating lubricant is needed, or during high-speed operations. Grease, however, is more common because its thicker consistency stays in place longer, providing extended lubrication and trapping contaminants to protect against abrasive wear.

In summary, while both oil and grease can serve as effective lubricants for solid bronze bushings, grease is the more typical choice due to its superior staying power and protective qualities. Whichever is chosen, the importance of proper lubrication cannot be overstated for maintaining the efficiency and longevity of these vital machine components.

BRONZE BUSHINGS GREASE

How much grease a bronze bearing can require when employed in a high-performance application?

Bronze bushings require lubrication due to the material’s nature.

A proper amount of grease can ensure the normal operation of the bronze bearing

Proper lubrication is crucial for the efficient operation of bronze bearings, which require significant amounts of grease, unlike self-lubricating polymer bearings. These bearings are favored in industrial machinery for their load-bearing capacity, wear and corrosion resistance, and temperature adaptability. However, they demand regular maintenance, particularly the correct application of grease.

While sufficient lubrication is essential, over-greasing can lead to bearing seizure, causing increased friction and heat, which can halt machinery and disrupt production, recognized to costly downtime and repairs. Therefore, maintaining the right grease balance is vital—too little causes wear, and too much causes seizure. Effective lubrication practices are part of a comprehensive maintenance strategy to ensure machinery operates smoothly with bronze bearings.

In summary, bronze bearings offer benefits but require careful maintenance and lubrication. Depending on your machinery’s needs, consider alternatives like self-lubricating polymer bearings.

Do Bronze Bearings Need Grease? Always?

Yes, bronze bearings generally require some form of lubrication in practically all applications. Lubrication is necessary to reduce friction, improve performance, and prolong the life of the bearings. Although there are instances where oil is used, most applications require the use of grease.

Lubrication not only ensures smooth operation, but it also necessitates regular maintenance and cleaning. This is because the lubricant can act as a magnet for contaminants such as dust and particulates. These contaminants can accelerate wear and tear on the bearing and negatively impact the overall lifespan of the machine.

While some bronze bearings are oil-impregnated to create a “self-lubricating” effect, it’s important to note that this design does not eliminate the need for maintenance and cleaning. Even with the “self-lubricating” feature, these bearings can still accumulate dust, dirt, and other particulates, and need periodic cleaning to ensure optimal performance.

To sum up, while bronze bearings are sturdy and durable, they require a certain level of maintenance, primarily due to the necessity of lubrication. Regular cleaning and adequate lubrication are paramount to reduce friction, prevent premature wear, and prolong the lifespan of the bearing and the machinery in which it is used. Regardless of whether a bronze bearing is self-lubricating or not, regular maintenance is key to optimal performance and longevity.

Alternatives to Greased Bronze Bearings: Which Material to Use?

Advanced bearing bush materials, including polymers and composites, provide a strong alternative to bronze bearings and bushings. Choosing the appropriate bushing material depends on the application, as these materials possess self-lubricating properties that eliminate the need for traditional lubricants like grease.

What oil is used for automatic refueling between the bronze bearing and the shaft?

Oil and grease can both be used, but grease cannot be automatically refueled.

This type of bronze bearing typically uses either a wear-resistant copper sleeve or a graphite copper sleeve. It is made from high-strength copper alloy (such as C86300, C83600, CuZn25Al5, CuZn24Al6Fe3Mn4) with solid lubricants added to its working surface based on specific conditions. The alloy provides high load-bearing capacity, while solid lubricants reduce friction.

For dry friction, we design a pre-lubrication film on the bearing surface to quickly transfer the solid lubricant to the mating part, forming an effective lubricating film. The oil film between the graphite copper sleeve and the shaft operates without the need for additional oiling.

MADE FOR YOU, SO YOU CAN MAKE MOVES

Properly specified self-lubricating bearings reduce maintenance costs, extend bearing life, and are environmentally friendly. These maintenance-free bearings enhance productivity with impact fatigue resistance, ensuring a longer service life. Their flexible design optimizes performance for your needs, lowering costs for bearings, lubrication systems, and maintenance. They maintain performance stability across various temperatures and support high load capacities, making them suitable for a wider range of applications.

When is it appropriate to use a bronze bearing instead of a bearing?

Bronze bearing , also known as copper roller, is one of the spare parts used in the manufacture of amorphous strips and magnetic materials of new materials, chromium, zirconium and copper.It is an important part of the belt swinging machine for composite bushing.

Swing belt with high quality, long service life, suitable for amorphous, microcrystalline alloy magnetic materials, ultra-high strength amorphous alloy and other alloy material swing belt.

Bronze bearings is one of the most commonly used parts in construction machinery, and it often cooperates with the machine body in interference. The original use of sledgehammer or press to press people, this method is prone to bumps, deforming the copper sleeve and forming a waste product. When the interference is large, simply peel off a layer of copper scraps from the surface of the copper sleeve, which will affect the quality of the device. At the same time, the labor intensity is high and the power is low. For this reason, we have tested the liquid nitrogen cold pack technology, and the effect is very good.

Bronze bushings instead of bearing is suitable for the following situations:

  1. Occasions where silence is required;
  2. The occasion of low speed;
  3. The load is relatively small occasions;
  4. Occasions where radial standard is limited;
  5. No dust constraint occasions.

In the construction machinery manufacturing and repair, especially in the chassis some have a lot of bronze bushing device, copper sleeve diameter shortening amount directly affects the quality of the device. After the bronze bushing device, it is necessary to check according to the technical requirements, and if necessary, it is also necessary to use reaming, milling, scraping and other methods for finishing, so as to ensure the coordination accuracy required between the inner hole of the copper sleeve and the shaft and the pin. In repair practice, the method of reserving the shortening amount of the inner hole is often used to simplify the device.

Bronze bushing bearing, is a very widely used in the belt swing machine, and is an indispensable part.It is used to manufacture amorphous single and magnetic materials of new chromium zirconium copper material, also known as copper roller.

Bronze bearing characteristics

The bronze bearing is made of new material chromium zirconium copper, which makes its hardness is relatively high, wear resistance is excellent, corrosion resistance in the atmosphere and fresh water is excellent, and in the process of use, it will not simply appear the appearance of biting dead. In addition, the bronze bearing also has good casting function and cutting function. The corrosion resistance function of copper sleeve is mainly manifested in its excellent corrosion resistance of dilute sulfuric acid, hydrochloric acid and fatty acids. It will not occur because the bronze bearing even in the absence of lubricants and water quality lubricants, it can still adhere to the excellent sliding and self-lubricating function; After all, the copper sleeve has a very high surface pressure, and the side pressure of its bearing is also good, so the impact resistance function and high load resistance ability of the copper sleeve are very good.

Bronze bearing application

Bronze bushing bearing can be used in high load and high sliding speed conditions for useful operations, and excellent wear resistance characteristics,  bronze bushings can often be used to manufacture connecting rod, bushing, bearing bush, gear, worm gear and other components;And it has good corrosion resistance and lubrication function, is very suitable for the layout of materials, corrosion and acid resistance accessories, crusher parts, piston pin sleeve, friction plate and other parts;The excellent casting and cutting functions of other copper sleeves make them very simple and cheap in the manufacturing of bimetal casting materials, general purpose layout parts, ship surfaces, sliders, sleeves and other parts.

  1. In the smelter, mine, steel plant rolling machinery and equipment about the choice of wear resistance of copper sleeve, bronze bushings of endurance, generally aluminum bronze.
  2. On the power plant, gas turbine, electric plant power equipment high demand bronze bushings.Most of this equipment is operated in succession, the force of the bronze bearing is particularly large, the assembly and disassembly are difficult, and it is not convenient to replace, so the quality of the bronze bushings is very stable, wear-resistant and pressure-resistant.
  3. Printing, packaging machinery, food machinery, special copper sleeve and outer spherical bronze bushings.
  4. Plastics, chemical fiber machinery, film drawing, special bronze bearing and high temperature bronze bushing. With the development of science and technology, this type of mechanical equipment continues to improve, change with each passing day; Some abroad, domestic also have very soon, with its copper cover also bring forth the new. Conveyor belts are mostly.
