Powder metallurgy bushings and sinter metals bushings with self-lubrication properties are designed to offer enhanced performance and durability in applications where lubrication may be limited or inconsistent. These bushings are manufactured through powder metallurgy processes, which allow for the creation of complex shapes and structures while maintaining high material integrity.
The self-lubrication feature of these bushings is achieved through the use of special materials or coatings that exhibit low friction and wear properties. This eliminates the need for external lubricants, reducing maintenance requirements and the potential for lubricant contamination or leakage.
Powder metallurgy bushings and sinter metals bushings with self-lubrication are widely used in industries such as automotive, aerospace, and heavy machinery. Their ability to withstand high loads, temperatures, and speeds while maintaining smooth operation makes them ideal for applications where reliability and durability are critical.

Description
Powder metallurgy has unique chemical composition and mechanical and physical properties, which cannot be obtained by traditional casting methods.Porous, semi-dense, or fully dense materials and products, such as oil-bearing bearings, can be made directly by powder metallurgy
Powder metallurgy is the process of making metal powder or metal powder (or mixture of metal powder and non-metal powder) as raw materials, forming and sintering, manufacturing metal materials, composite materials and various types of products.Powder metallurgy and ceramic production are similar, both belong to powder sintering technology, therefore, a series of new powder metallurgy technology can also be used for the preparation of ceramic materials.Due to the advantages of powder metallurgy technology, it has become the key to solve the problem of new materials, plays a pivotal role in the development of new materials.

Copper sleeve, Self lubricated bearing, used in a variety of large, heavy machinery, machinery is an important component.
Copper sleeve, copper bearing, used in various light industry, large, heavy machinery, is an important component of machinery.The product has the traditional tin bronze bearing function, takes the electrolytic copper as the raw material to match with many kinds of trace metal elements, through the high temperature sintering, through the air pressure centrifugal casting processing becomes.High hardness, excellent wear resistance, not easy to die, good casting performance and cutting performance, good corrosion resistance in the atmosphere and fresh water.In the absence of lubricants and water-quality lubricants, good sliding and self-lubricating properties, easy cutting, poor casting performance, good corrosion resistance to dilute sulfuric acid.Structural parts for general use, simple castings for ships, instruments, etc., such as sleeve, bushing, bearing bush, sliders, etc.

| Self-lubricating - when in motion oil rises to the surface for lubrication and restores itself when at rest. |
| After forming, sintering and sizing, the bearings are vacuum impregnated with SAE 30 oil that provides lubricant which is metered from the bearing to the shaft during rotation. |
| Standard off-the-shelf oil impregnated bronze bearings should function satisfactorily in temperatures ranging from 10F to 220F. |
| RoHS, REACH, DFARS compliant |
Advantages Of Powder Metallurgy Process
· Do not need or only very little machining
· High usage rate of material(more than 95%)
· Parts size consistency is good and stable. The precision can reach 0.01mm.
· The material composition can be adjusted according to the customers’requirement of the parts performance.
· Do the treatment on the surface of the parts according to customers’ requirement to improve the strength and hardness.
· Due to the die forming, we can customize the complex shape or special profiled parts which other machining can not do.
· Because suitable for mass production, the production efficiency is high and the cost is lower than machining.
