Phosphor bronze: Copper alloy containing 2% ~ 8% tin, 0.1% ~ 0.4% phosphorus and the remainder copper. Mainly used as wear-resistant parts and elastic components. Brass: Brass is an alloy of copper and zinc. If brass consists only of copper and zinc, it is called plain brass. A variety of alloys consisting of more than two elements is called special brass. Such as copper alloys consisting of lead, tin, manganese, nickel, lead, iron, and silicon. Brass has strong wear resistance.

Phosphor bronze bushings feature high hardness, good wear resistance, low friction coefficient, good toughness, high allowable specific pressure and high limit line speed, and good processability. We offer various phosphor bronze bushings, and they are widely used in electric machinery, machine tools, tractors, ships, sugarcane pressing, paper making, cement equipment, polygraphy, light industry.

Phosphor Bronze is a copper alloy that contains significant amounts of phosphorus. The alloy also contains 0.5-11% tin. Historically, it is one of the oldest metal alloys in the world, dating back almost 4,000 years.

The material is extremely well known for its strength, durability, low coefficient of friction and fine grain. Given the presence of phosphorus, the alloy has great fluidity in the molten state and therefore offers good castability. Phosphorus acts as a deoxidizer, reduces viscosity and therefore improves fluidity, increasing stiffness and wear resistance. The introduction of tin, on the other hand, determines a significant increase in strength and resistance to corrosion.

The difference between self-lubricating bearing and oil-bearing:

oil-bearing takes metal powder as the main raw material and sintered body made by powder metallurgy. It is porous in nature and has the technical advantages of being able to freely adjust the number, size, shape, and distribution of pores in the manufacturing process. Make use of the porosity of the sintered body, so that it contains 10%~40%(volume fraction) lubricating oil, and it is used under the condition of self-feeding oil. When running, the bearing temperature rises, because the expansion coefficient of oil is larger than that of metal, it automatically enters the sliding surface to lubricate the bearing. Oil-bearing oil can be used for a long time, often used for refueling inconvenient occasions.
Metal base inlaid solid self-lubricating bearing is a novel lubricating bearing that has both the characteristics of metal bearing and self-lubricating bearing. The metal base bears the load, and the solid lubricating material with special formula plays the lubrication role. It has the characteristics of high bearing capacity, impact resistance, high-temperature resistance, strong self-lubrication ability, especially suitable for heavy load, low speed, reciprocating or swing, and other difficult lubrication and oil film formation occasions, also not afraid of water and other acid erosion and scouring. Inlaid bearings not only save oil and energy, but also their working life is longer than ordinary plain bearings. At present, the products have been widely used in a metallurgical continuous casting machine, rolling equipment, mining machinery, ships, steam turbines, water turbines, injection molding machines,s and equipment production lines.

1. Oil-bearing is a combination of metal powder with 10~40% structural clearance; The matrix of inlaid self-lubricating bearing is made by centrifugal casting. The substrate density is relatively high, the binding strength is higher than that of oil-bearing bearings, and the service life is longer than that of oil-bearing bearings.

2. The lubricating material of oil-bearing is lubricating oil, and the oil film has enough thickness to eliminate the direct contact between the two friction surfaces. At this point, there is only friction between liquid molecules, so the friction coefficient is very small (F = 0.001-0.008), which significantly reduces friction and wear. The lubricating material of embedded self-lubricating bearing is solid lubricating material. Even in the condition of no oil, it can still achieve good lubrication effect and ensure the uninterrupted and sustainable lubrication. Its effective lubrication life is consistent with the life of the matrix.

3. The lubricating oil in the oil-bearing is volatile and easy to lose, and the lubricating oil film loses faster under high temperature and high pressure, so it cannot achieve the due lubrication effect; And the solid lubricant through friction, solid lubricant in the hole or groove to the friction surface transfer or reverse transfer, in the friction surface to form good lubrication, solid adhesion and uniform coverage of the solid transfer film, greatly reduce the friction and wear. As the friction goes on, the solid lubricant embedded in the friction surface is constantly provided to ensure the good lubrication of the friction pair during long-term operation.

Our company produces oil-bearing, self-lubricating bearing graphite copper bushing, advanced casting technology, can effectively prolong the life of mechanical parts.
