Self-lubricating Bearing Bushings: The Oil-Free Effect
“Self-lube bushings” is a term used in mechanical engineering and refers to a type of bushing or bearing that incorporates a lubricating material within the structure of the bushing itself. This means that the bushing does not require additional lubrication during operation and can self-lubricate, reducing maintenance requirements and extending the life of the bushing.

How Do Self-Lubricating Bearings Work?
Self-lubricating bearings combine a durable metal substrate (typically copper) with embedded solid lubricants like graphite. During operation:
-
The metal substrate bears the primary load, ensuring structural integrity.
-
Friction triggers the release of lubricant from embedded pores, forming a smooth, protective transfer film on the bearing surface.
-
This film minimizes wear, reduces friction coefficients, and eliminates the need for external lubrication.
-
Continuous lubricant replenishment ensures consistent performance and extended service life, even in harsh environments.
Ideal for applications where traditional lubrication is impractical, our bearings prevent seizing, reduce downtime, and enhance operational efficiency.

Self Lube Bushings - What are the options
Self-lubricating bushings, also known as self-lube bushings, are a type of bearing that operates without the need for external lubrication. There are several options available for self-lube bushings, including:
- Solid metal bushings: These are made from materials like bronze, brass, or steel and have a built-in lubricant that is evenly distributed throughout the material. They are typically used in high load and low-speed applications.
- Composite bushings: These are made from a combination of materials such as PTFE (polytetrafluoroethylene) or nylon and are designed for high-speed and low-load applications. They have a low coefficient of friction and are resistant to wear.
- Metal and bimetal bushings: These are made from metals that are compressed and sintered together to form a solid piece. They are typically used in high-load and low-speed applications.
- Composite bushings: These are made from materials such as acetal or PTFE and are designed for low-load and high-speed applications. They have a low coefficient of friction and are resistant to wear and corrosion.
- Graphite bushings: These are made from graphite impregnated materials and are designed for high-temperature applications. They have a low coefficient of friction and can withstand extreme temperatures without losing their lubricating properties.
The choice of self-lubricating bushing will depend on the specific application requirements, such as load, speed, temperature, and environment. It is important to choose the right self-lubricating bushing to ensure reliable and efficient operation
What are self-lubricating bearings? Self-lubricating bearings and self-lubricating materials
With the continuous progress of science and technology today, mechanical technology is moving towards advanced, sophisticated, diversified trends. Especially aerospace technology, atomic energy industry, military industry and other research fields plain bearing technology is facing many new issues, for example, self-lubricating bearing in vacuum conditions, high-temperature conditions and low-temperature conditions and other extreme environmental problems, its solution mainly relies on self-lubricating bearings of special lubrication properties. Self-lubricating bearing is the rolling body, inner and outer ring raceway or cage after special material treatment, no need to add oil or grease lubricants can work properly bearings. Self-lubricating bearings from the lubrication mechanism can be divided into self-lubricating material itself to produce self-lubricating characteristics of bearings and sintered microporous material due to the nature of the self-lubricating characteristics of bearings.

Self-lubricating plain bearings from the lubrication mechanism can be divided into self-lubricating material itself to produce self-lubricating characteristics of plain bearings and sintered microporous materials due to the nature of the self-lubricating characteristics of bearings.
Self-lubricating bearings, self-lubricating bearing characteristics
Lubrication is divided into fluid lubrication, mixed lubrication, boundary lubrication, and solid lubrication. In the field of solid lubrication, the bearing material itself shows good friction characteristics, wear resistance of the bearing is called self-lubricating bearings. Because self-lubricating bearings are used in parts where lubricant cannot be used or in parts where the lubricant is poor and used in boundary lubrication, mixed lubrication and other stable parts, this self-lubricating bearing is also called "self-lubricating bearing", "dry bearing" and so on.
Self-lubricating plain bushes bearings have the following characteristics.
1) self-lubricating bearing low friction: in the use of solid lubricants, direct friction between solids is a small coefficient of friction.
2) self-lubricating bearing heat resistance: solid lubrication and fluid lubrication compared to the coefficient of friction are small, and therefore can withstand the friction (direct friction between solids) generated by the high heat.
3) self-lubricating bearing sinter resistance: not easy to sinter.
4) self-lubricating bearing wear resistance: not easy to wear.
(5) self-lubricating bearing environmental adaptability (corrosion resistance): can withstand the air, gas, and working oil on its chemical corrosion effect.
Self-lubricating plain bearings materials, which type of bearing metal is self-lubricated
Self-lubricating bushes are a type of bearing that are designed to operate without the need for external lubrication. They are commonly used in applications where traditional lubricants cannot be used or where frequent lubrication is not practical.
Self-lubricating bushes are made from a variety of materials, including:
- Bronze: Bronze self-lubricating bushes are commonly used in high-load, low-speed applications. They are known for their high wear resistance and ability to withstand harsh environments.
- Graphite: Graphite self-lubricating bushes are commonly used in high-temperature applications. They have a low coefficient of friction and can withstand extreme temperatures without losing their lubricating properties.
- PTFE: PTFE self-lubricating bushes are commonly used in high-speed, low-load applications. They have a low coefficient of friction and are resistant to chemicals and corrosion.
- POM: POM self-lubricating bushes are commonly used in low-load, high-speed applications. They have a low coefficient of friction and are resistant to wear and abrasion.
Self-lubricating bushes are an excellent choice for applications where frequent lubrication is not practical or where traditional lubricants cannot be used. The choice of material will depend on the specific application requirements, such as load, speed, temperature, and environment.
self-lubricating bearing material types
Plain Bearing material type, which type of bearing metal is self
The so-called self-lubricating bearing materials are not even from the outside to provide lubricant itself can show the low friction characteristics of the material. Its representative is, tetrafluoroethylene resin and other plastics containing graphite, molybdenum fluorescence and other solid lubricants of plastic-bearing materials. In addition, there are also materials with solid lubricants synthesized with metals, bearing materials with graphite added to metal base materials, etc. Special examples include essential and rubber bearing materials. Broadly speaking, there are also oil-bearing materials with lubricating oil immersed in the material included in self-lubricating bearing materials.
Self-lubricating Bushing Bearing material characteristics
Plain bearing materials
Self-lubricating bearing materials also have the most common materials. Plastic bearing material is divided into solid lubricant dispersion type material, double layer type material, being compound type material, porous material. Solid lubricant dispersion type material is the solid lubricant dispersion into the plastic material, double layer type material is lined with metal and metal powder depletion layer and plastic layer composition of the material. Also, the compound material is the material to which the plastic and solid lubricant are attached on the surface of the base material such as metal. The porous material is a material consisting of plastic and metal eyelet, etc.
a. Solid lubricant dispersion type material
Plastic bearing material is the most used material in various applications. It is a bearing material in which solid lubricants such as graphite, molybdenum fluorescence, PTEE resin, etc. are mixed with lubricating oil and dispersed together in plastic, and then injection molding and compression molding, and also has the advantage that it can be processed into various shapes by mechanical processing.
b. Double-layer material
Double-layer material is a double-layer structure of metal lining, metal powder sintered layer, and a plastic layer of bearing material. Since it is a double-layer structure, the heat generated by friction is quickly dissipated, and it also makes up for the weakness of plastic and its self-heating conduction. For this reason, it is a high-performance bearing material with good resistance to high loads compared to solid lubricant dispersion-type materials.
c. Compounded material
It is a material that forms a film of solid lubricant such as resin and molybdenum dichloride directly on the surface of the basic material such as metal and is used under less strict conditions.
d. Porous material
The porous material is a bearing material impregnated with tetrafluoroethylene resin, etc., in the metal eyelet space. The softness of the eyelet is used to sandwich it between the shaft and the sleeve to reduce the bearing clearance and prevent the shaft from loosening, and the resin (PTEE) inside has a low coefficient of friction.
For the above material, the main component of the friction surface is plastic. This material, the use of tetrafluoroethylene resin, polyacetal, polyamide, polysulfide benzene, polymethyl ethyl copper, and other thermoplastic resins and epoxy, carbolic acid, polyamide-imide, polyimide, and other thermosetting resins. As the choice of these materials, it is not all without lubricating oil parts, and thus can be used in lubrication, butter and water and a wide range of lubrication conditions, and according to its use, type to provide a variety of rich material bearings.
Other self-lubricating bushing bearing materials
In addition to plastic class (bearing material), there are solid lubricant and metal synthesis of solid lubricant dispersion type material, rod graphite, and other solid lubricants filled into the copper alloy solid lubricant filling type bearing material, or lubricant dipped into the copper alloy, iron alloy and become oil-containing sintered bearing material. In addition, special also have wood type bearing material, rubber type bearing material, etc.

What is a plain bearing?
Beautifully crafted leather products.
A plain bearing, specifically a self-lubricating sliding bearing, operates under sliding friction. These bearings function smoothly, reliably, and quietly. When liquid lubrication is present, the sliding surfaces are separated by oil, minimizing direct contact, friction loss, and surface wear, while also providing some vibration absorption. However, they do experience high starting friction resistance. The shaft portion supported by the plain bearing is known as the journal, and the components that interact with it are called shingles. To enhance the frictional properties, a layer of friction-reducing material, known as the plain bearing lining, is cast on the inner surface. The shaft and the liner materials are collectively referred to as plain bearing sliding bearing material. Plain bushing bearings are typically used in low-speed, heavy-load conditions or in environments where maintenance and lubrication are challenging.

How do self lubricating bearings work?
What is the principle of self-lubricating bearings? Self-lubricating bearings working principle: Self-lubricating bearing using composite material is a new type of anti-polar pressure solid lubrication material, by the metal substrate and embedded in the substrate hole or slot of solid lubricant paste composition. Self-lubricating bearings with copper as the substrate, inlaid graphite material, in the work of the metal substrate to bear most of the friction load. After friction, the solid lubricant in the hole or slot is transferred or counter-transferred to the friction surface, forming a well-lubricated, firmly attached and uniformly covered solid transfer film on the friction surface, significantly reducing frictional wear. As the friction proceeds, the embedded solid lubricant is continuously provided to the friction surface, ensuring good lubrication to the friction substrate during long-term operation.

How does self lubricating bearings work? Bearings are a mechanical component often used in machine tools, but some industrial enterprises work and production environment is relatively harsh, often accompanied by sulphur dioxide and other corrosive gases and dust in the work of mechanical equipment damage, resulting in machine tools in the work of friction and wear serious, in order to reduce the occurrence of such situations, self-lubricating bearings began to be developed and applied in the use of machine tools machinery, we take a look at self-lubricating What is the working principle of self-lubricating bearings.
Self-lubricating bearings using composite materials is a new type of anti-pressure solid lubricating material, by the metal substrate and embedded in the substrate of the hole or slot in the solid lubricant paste composition. In the friction process, the metal substrate bears most of the load. After friction, the solid lubricant in the hole or slot is transferred or counter-transferred to the friction surface, forming a well-lubricated, firmly attached and uniformly covered solid transfer film on the friction surface, which greatly reduces frictional wear. As the friction proceeds, the embedded solid lubricant is continuously provided on the friction surface, ensuring good lubrication for the frictional subsets during long-term operation.
The emergence of self-lubricating bearings for industrial production reduces a lot of manpower and material resources, reduces the friction or bite phenomenon between the bearings and other parts in the operation, ensures the normal operation of the machine tool mechanical parts, for the production of continuous operation to do a guarantee. The self-lubricating bearings produced by our company can be used without or with less lubricating oil, with good wear resistance and small friction coefficient, and have a long service life.
