Powder Metallurgy Copper Base Oil bearing
Oil-impregnated bearings, namely Porous Bearings, use metal powder as the main raw material. Oil-impregnated bearings are sintered bodies made by powder metallurgy, which are inherently porous and have pores that can be adjusted more freely during the manufacturing process. Technical advantages of quantity, size, shape and distribution.
This type of product is used in various transmission devices, including various micro motors, office equipment, household appliances, etc. It is characterized by good wear resistance, long life and low noise. The materials are mainly iron series, copper series and iron copper series.
working principle  
Using the porous characteristics of the material or the affinity with lubricating oil, before the bearing pad is installed and used, the lubricating oil is infiltrated into the bearing pad material, and the bearing can be left without lubricating oil or for a long time during operation. This kind of bearing is called an oil bearing. When the oil-impregnated bearing is in a non-operating state, the lubricating oil fills its pores. During operation, the shaft rotates and generates heat due to friction, and the thermal expansion of the bearing bush reduces the pores, so the lubricating oil overflows and enters the bearing gap. When the shaft stops rotating, the bearing bush cools, the pores recover, and the lubricating oil is sucked back into the pores.
Features
It has the characteristics of low cost, vibration absorption, low noise, and no need to add lubricating oil in a long working time. It is especially suitable for working environments that are not easy to lubricate or do not allow oil to be dirty. Porosity is an important parameter for oil-impregnated bearings. Oil-impregnated bearings that work at high speed and light load require a large amount of oil and high porosity; oil-impregnated bearings that work at low speeds and large loads require high strength and low porosity. This kind of bearing was invented in the early 20th century. Because of its low manufacturing cost and convenient use, it has been widely used and has become an indispensable part of the development of various industrial products such as automobiles, home appliances, audio equipment, office equipment, agricultural machinery, and precision machinery. A class of basic parts. Oil-impregnated bearings are divided into copper-based, iron-based, copper-iron-based, etc.

What is Powder Metallurgy Copper Base Oil bearing
Powder metallurgy copper-based oil bearings, also known as sintered copper bearings, are a type of self-lubricating bearing made using powder metallurgy techniques. These bearings are commonly used in various applications where low friction and self-lubrication are required.
Powder metallurgy is a manufacturing process that involves compacting metal powders into a desired shape and then heating the compacted powder to fuse the particles together. In the case of copper-based oil bearings, copper powder is used as the primary material.
Steps for Making Powder Metallurgy Copper Base Oil bearing
The manufacturing process of powder metallurgy copper-based oil bearings typically involves the following steps:
1.Powder Blending: Copper powder is mixed with other additives such as solid lubricants, binders, and sometimes alloying elements to enhance specific properties.
2.Compaction: The blended powder mixture is compacted under high pressure in a die to form a green compact. The pressure helps in achieving the desired shape and density.
3.Sintering: The green compact is then heated in a controlled atmosphere furnace to a temperature below the melting point of copper. During sintering, the copper particles bond together, resulting in a solid and porous structure.
4.Infiltration: In some cases, the sintered part is further impregnated with oil or a solid lubricant to enhance its self-lubricating properties. This process is known as infiltration.
The resulting powder metallurgy copper-based oil bearing has a porous structure that allows for the retention and distribution of lubricating oil. The embedded solid lubricants or oil reservoirs within the bearing provide a continuous lubrication film, reducing friction and wear between the bearing and the mating surfaces.
