    The plain bearings are designed in such a way that they can be pressed into a housing (with an H7 tolerance) with the nominal size of the bearing outer diameter and are then secured by the press-fit. This is achieved by the so-called press-in excess, i.e. the outside diameter of the bearing is, depending on the nominal size, about 0.1 to 0.25 mm larger than the housing in the non-pressed state. The inner diameter also reaches its final dimensions and tolerances only when pressed in.

    Why are there so many different bushings materials?

    The variety of bushing materials developed from the obligation to meet a variety of customer requirements over the past years.

    Self-lubricating bearings are divided into composite self-lubricating bearings, solid embedded self-lubricating bearings, bimetallic material self-lubricating bearings, and special material self-lubricating bearings. According to different uses and working conditions, different self-lubricating bearings are selected.
    One of the major categories of solid inlaid self-lubricating bearings (JDB for short) is a novel lubricating bearing with both the characteristics of metal bearings and oil-free bearings. The metal matrix bears the load, and the solid lubricating material with special formula plays the role of lubrication.
    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. Products have been widely used in metallurgical caster, rolling equipment, mining machinery, mold, lifting machinery, textile machinery, wind power generation, ships, steam turbines, water turbines, injection molding machine and equipment production line. Wear resistance is one times of ordinary sleeve.

    Durable materials.
    Which should I choose?

    The advantages of self-lubricating bearings (oil-free bearings), most of the bearings used in various machinery industries are ball bearings, needle rolls, and so on, but a small part of the use of self-lubricating bearings, I believe that in the near future will come from lubricating bearings will become the dominant bearings.
    The following are the application characteristics and advantages of partially self-lubricating bearings:
    Oil free lubricated bearing series
    Self-lubricating bearing
    Self-lubricating bearing
    1, no oil lubrication or less oil lubrication, suitable for refueling or difficult to refueling places, can be used without maintenance or less maintenance.
    2, good wear resistance, small friction coefficient, long service life.
    3. With the right amount of elastoplastic, the stress can be distributed on a wider contact surface and the bearing capacity can be improved.
    4, static and dynamic friction coefficient is similar, can eliminate crawling at low speed, so as to ensure the working accuracy of machinery.
    5, can make the machine reduce vibration, reduce noise, prevent pollution, improve working conditions.
    6, in the process of operation can form a transfer film, play a protective role on the grinding shaft, no shaft biting phenomenon.
    7, for grinding shaft hardness requirements are low, without quenching and tempering treatment of the shaft can be used, so as to reduce the processing difficulty of the relevant parts.
    8, thin-wall structure, lightweight, can reduce the mechanical volume.
    9, the back of steel can be electroplated with a variety of metals, can be used in corrosive media; It has been widely used in sliding parts of various machinery, such as printing press, textile machine, tobacco machinery, micromotor, automobile, motorcycle and agricultural and forestry machinery, etc.
    Boundary lubricated bearing series
    1. Good bearing capacity, good wear resistance.
    2. It is suitable for rotating motion and swinging motion under high load and low speed, and for occasions where opening and closing frequently under load is not easy to form hydrodynamic lubrication.
    3. In the condition of boundary lubrication, it can be long-term without refueling and maintenance, while refueling in the layer makes the bearing longer service life.
    4. The plastic layer on the surface can leave a certain allowance when processing and forming, and can be processed by itself after assembling and pressing into the seat hole, so as to achieve better assembly size.
    5. The products are mainly used in automobile chassis, metallurgical machinery, mining machinery, water conservancy machinery, construction machinery, agricultural machinery, steel rolling equipment, etc.
    JDB solid inlaid bearing series
    General basic products, whether high pressure, low pressure, high temperature, low temperature, oil lubrication, oil free lubrication or water lubrication, can be adapted. The base of the product is high force brass, which is twice as hard as the general copper sleeve and more than twice as wear-resistant.
    Widely used in: light industry machinery, heavy industry machinery, construction machinery, metallurgical machinery, conveying machinery, such as: continuous casting machine, rolling mill, injection molding machine, paper machine, mold guide post, ships, machine tools and so on.

    Unfortunately, there is no such thing as “the best self-lubricating plain bearing”. The bearing with the highest price is not always the longest lasting one in all applications. But there is a better bronze oilless bearing for your application.
    It is important to always choose your bearing in relation to the application in which it is to be used. The more that is known about the application, the more precise the selection of bearing that makes the most sense in technical and economic terms.
    Our oilless bronze bearings product finder and bushing guide service design can help here. Simply give us your size data and we will do the rest.

    Contact with chemicals is often a particularly difficult challenge for plain bearings. For instance, the food industry uses disinfectants or cleaners, or the bearings come into contact with coolant. Self-lubricating bearingsmaterials are tested for resistance to a large number of chemicals. So that they can be used in applications in which they come into contact with disinfectants, cleaners or other chemicals. Stainless steel backed PTFE bushing materials are considered particularly resistant to chemicals.

    Polytetrafluoroethylene (PTFE) is a synthetic fluoropolymer of tetrafluoroethylene that has numerous applications. The best known brand name of PTFE-based formulas is Teflon by DuPont Co., who discovered the compound.PTFE is a fluorocarbon solid, as it is a high-molecular-weight compound consisting wholly of carbon and fluorine. PTFE is hydrophobic: neither water nor water-containing substances wet PTFE, as fluorocarbons demonstrate mitigated London dispersion forces due to the high electronegativity of fluorine. PTFE has one of the lowest coefficients of friction against any solid.PTFE is used as a non-stick coating for pans and other cookware. It is very non-reactive, partly because of the strength of carbon–fluorine bonds and so it is often used in containers and pipework for reactive and corrosive chemicals. Where used as a lubricant, PTFE reduces friction, wear and energy consumption of machinery. It is also commonly used as a graft material in surgical interventions.

    We are the manufacturers of Teflon / PTFE Coated Steel Backed Bush, Metal Bushings Lubricated and Graphite Filled Bushes.

    Teflon high-performance special coating is a fluorine coating with polytetrafluoroethylene as the matrix resin. The English name is Teflon. Because of the pronunciation, it is usually called Teflon, Teflon, Teflon, etc. Teflon, etc. (all Teflon transliteration). Teflon (Teflon) coating is a unique high-performance coating that combines heat resistance, chemical inertness, excellent insulation stability and low friction, and has comprehensive advantages that other coatings cannot compete with. It is flexible in application. The sturdiness allows it to be used on almost all shapes and sizes of products.

    Teflon is divided into several basic types: PTFE, FEP, PFA, ETFE:

    1. Teflon PTFE: PTFE (polytetrafluoroethylene) non-stick coating can be used continuously at 260 °C, with a maximum operating temperature of 290-300 °C, extremely low friction coefficient, good wear resistance and excellent chemical stability sex.

    2 Teflon FEP: FEP (fluorinated ethylene propylene copolymer) non-stick coating melts and flows during baking to form a non-porous film, with excellent chemical stability, excellent non-stick properties, and a maximum service temperature of 200 ° C .

    3. Teflon PFA: PFA (perfluoroalkyl compound) non-stick coating, like FEP, melts and flows to form a non-porous film during baking. The advantages of PFA are that it has a higher continuous use temperature of 260 ° C, stronger rigidity and toughness, and is especially suitable for use in the field of anti-sticking and chemical resistance under high temperature conditions.

    4 Teflon ETFE: ETFE is a copolymer of ethylene and tetrafluoroethylene. This resin is the toughest fluoropolymer and can form a highly durable coating with excellent chemical resistance and can be used at 150 ℃ continuous work.

    After Teflon coating, it has the following characteristics:

    1. Non-stick: almost all substances are not bonded to the Teflon coating. Very thin films also show good non-stick properties.

    2. Heat resistance: Teflon coating has excellent heat resistance and low temperature resistance. It can withstand high temperature up to 300 °C in a short time, and can be used continuously between 240 °C and 260 °C. It has significant thermal stability. It can work at freezing temperature without embrittlement and will not melt under high temperature.

    3. Sliding: Teflon coating has a low coefficient of friction. The coefficient of friction changes when the load slides, but the value is only between 0.05-0.15.

    4. Moisture resistance: The surface of the Teflon coating is free from water and oil, and it is not easy to be stained with solution during production operations. If there is a small amount of dirt, it can be removed by simply wiping. Short downtime saves man-hours and increases productivity.

    5. Wear resistance: under high load, it has excellent wear resistance. Under a certain load, it has the dual advantages of wear resistance and non-adhesion.

    6. Corrosion resistance: Teflon is hardly corroded by chemicals and can protect parts from any kind of chemical corrosion.

    A homogeneously structured plain bearing with predictable properties is made of a high-performance metal.

    Some engineers hesitate to use metal and bronze bearings in their designs. Maybe they have trusted deep groove bearings or plastic bearings for years or they simply don’t think metal or bronze bushing can handle the tough applications or environments. Metal self-lubricating bearings, however, can endure extreme temperatures, heavy loads, and high speeds. However, it’s important to understand both the advantages and disadvantages of the options available. Self-lubricating composite bearings contain solid lubricants material. In operation, these solid lubricants reduce the coefficient of friction. They cannot be washed off like fat or oil and due to the homogenous structure, they are distributed over the entire wall thickness of the bearing. The wall thickness of the bearing is available flange size and plate.

    1: Wear inspection of self-lubricating bearings by

    Influencing factors:

    Shaft selection: Different shafting materials are recommended for different types of self-lubricating bearings. Each shaft-bearing combination will have different wear results.

    Load: With increasing radial loads and/or surface pressures, the wear of the plain bearings also rises. Some self-lubricating bearings are designed for low loads, some for high loads.

    Speed and type of movement: With increasing speed, the wear also increases. The type of movement (oscillating, rotating, or linear) has considerable influence on the rate of wear.

    Temperature: Within certain limits, the temperature barely affects the wear of self-lubricating bearings, but it can also exponentially accelerate the wear. Depending on the self-lubricating bearings material selection, metal bushing sliding bearings are indeed suited for a wide temperature range. However, when the maximum application temperature is exceeded, the wear can increase significantly. In most self-lubricating bearings materials the rate of wear increases with rising temperatures. There are also exceptions, which only reach their minimum wear at higher temperatures.

    Dirty surroundings: Dirt and dust can accumulate between shaft and bearing. That causes wear. Self-lubricating metal bushings offer an advantage in this situation: they operate oil-free so dirt and dust will not score the shaft or damage the bearing.

    Contact with chemicals: Composite self-lubricating bearings are absolutely corrosion-free and resistant against a wide range of chemicals, but certain chemicals can even change the structural properties of a plain bearing, which decreases the self-lubricating bearings’ hardness and increases the wear.

    2: Wear tests using different types of shafting.

    Applicable to all these points is the better I know my application and the mentioned parameters, the more specific the self-lubricating bearings material selection and service life prediction can be. The selection of the right material is decisive for the service life.

    declaration of hazardous substances management regulations

    All self-lubricating bearings type materials with this mark comply with RoHS directive requirements


    On 4 June 2015, the European Union published in the Official Journal Directive (EU) 2015/863 amending Annex II of directive RoHS 2.0 (2011/65/EU) on the requirements for restricted substances by adding four controlled substances of phthalate esters. Bis (2-ethylhexyl) phthalate (DEHP), butylbenzyl phthalate (BBP), dibutyl phthalate (DBP), diiso-butyl phthalate (DIBP), and the content of the four phthalate esters in homogeneous materials shall not exceed 0.1%, so there are ten mandatory control substances in Appendix II. They are four heavy metals, two brominated flame retardants and four o-benzene plasticizers.


    ELV is a directive for the European Commission and the European Parliament on the recycling of end-of-life vehicles in order to protect the environment and reduce the amount of waste produced by end-of-life vehicles. Lead, cadmium, mercury and hexavalent chromium are banned from automobiles produced after July 2003.

    Limits of prohibited components in all parts and materials:

    Cadmium (Cd) 100 PPM or less (0.01%).
    Mercury (Hg) 1000 PPM or less (0.1%).
    Lead (Pb) 100 PPM or less (0.1%).
    Hexavalent Chromium (CrVI)≤1000ppm (0.1%)

    The directive governs the restrictions on undesired ingredients in electrical and electronic equipment sold within the EC. The RoHS abbreviation means “Restriction of (the use of certain) Hazardous Substances” .
    Specific threshold values were established since there are technical limitations in many materials and products that do not permit a complete elimination.
    The affected substances are frequently used in electronics and include lead, mercury, cadmium, hexavalent chrome, polybrominated biphenyls (PBB), and diphenyl ether (PBDE). Application examples include the use of lead in solder, or as an ingredient in metallic composite bearings, and the use of PBB as a flame retardant. The substances also frequently occur in metallic alloys.
