    PTFE composite bearings have good dry sliding characteristics and do not require lubrication. However, the presence or continuous supply of oil or other fluids may be advantageous. Even fluids not normally associated with lubrication, such as water, kerosene or paraffin, may be used. Lubrication may improve heat removal and hydrodynamic lubrication film formation at the bearing location. As a result, lubrication has a very favorable effect on the wear behavior of bearings and greatly extends their life.

    Periodic relubrication with grease to strengthen the seal or protect the counterside from corrosion can also extend the life of the bearing.

    However, when mounting PTFE composite bearings, a single initial grease may have a negative effect on the life of the bearing, as the grease forms a paste-like mixture with wear particles generated during the grinding process, increasing the wear of the bearing.

    At operating temperatures up to 80 °C, an anti-aging lithium-based grease is preferred, while at higher temperatures, a silicone grease should be used. Greases containing solid lubricants (e.g. molybdenum disulfide) are totally unsuitable.

    Materials
    Design and variants Steel backing with a layer of sintered tin/bronze pores filled and covered with a layer of POM composite

    The POM composite plain bearing is designed to operate under marginally lubricated conditions. Its sliding surface contains a grease reservoir that should be filled prior to installation. There is no need to relubricate these plain bearings, but the presence of lubricant can greatly extend the life of the bearing.

    To protect the mating surfaces from corrosion, grease can be applied periodically. For this reason, POM composite bushings with a bore diameter d ≥ 10 mm and a width B ≥ 12 mm are manufactured with lubrication holes. The size and location of the holes are in accordance with DIN 1434.

    At operating temperatures up to 80 °C, it is preferable to use age-resistant lithium-based greases, while at higher temperatures, silicon-based greases should be used. Greases containing solid lubricants such as molybdenum disulfide are completely unsuitable.

    Bushings and plain bearings are crucial components in many mechanical systems, providing a wear-resistant interface between two parts, usually between a rotating and a stationary component. One of the critical aspects of their functionality and longevity is lubrication. Proper lubrication reduces friction, minimizes wear, and prolongs the life of the bearing. Here’s a breakdown of lubrication as it relates to bushings and plain bearings:

    Types of Lubrication for Bushings and Plain Bearings:

    1. Hydrodynamic Lubrication:
      • Here, a continuous lubricant film separates the bearing surface from the shaft, preventing metal-to-metal contact. The relative motion between the surfaces causes the lubricant to form this film.
    2. Boundary Lubrication:
      • In situations where full-film lubrication is difficult, a thin film covers the bearing surfaces. This film isn’t thick enough to completely separate the surfaces, so some asperity contact may occur. Special additives in the lubricant can help prevent wear in these conditions.
    3. Mixed Lubrication:
      • This is a combination of hydrodynamic and boundary lubrication. A portion of the bearing surface is separated by a lubricant film, while other areas might have asperity contact.
    4. Solid Lubrication:
      • Solid materials, such as graphite or PTFE (Polytetrafluoroethylene), are used to reduce friction. These are often embedded in self-lubricating bearings or applied as a coating.
    5. Grease Lubrication:
      • Grease is a semi-solid lubricant and is often used in applications where liquid lubricants are unsuitable. It remains in place, offering long-lasting lubrication, and can also act as a sealant to prevent contaminants from entering the bearing.

    Factors Affecting Lubrication:

    1. Load: Higher loads can squeeze out lubricants, requiring more robust or more frequent lubrication.
    2. Speed: At high speeds, there’s a need for lubricants with good film strength. Conversely, low speeds might not generate a sufficient hydrodynamic film.
    3. Temperature: High temperatures can cause some lubricants to break down or evaporate. The choice of lubricant should be compatible with the operational temperature range of the bearing.
    4. Environment: In dusty or corrosive environments, the lubricant should also serve as a protective barrier against contaminants.

    Benefits of Proper Lubrication:

    1. Reduced Wear: Lubrication minimizes direct contact between the bearing and shaft, leading to reduced wear.
    2. Lower Friction: Proper lubrication ensures that friction is minimized, leading to smoother operation and reduced heat generation.
    3. Dissipation of Heat: Lubricants can help carry away heat generated due to friction.
    4. Protection: Lubricants can protect the bearing surface from corrosion and contaminants.

    Conclusion:

    Lubrication is a critical aspect of bushing and plain bearing operation. The right type and amount of lubricant, applied correctly, can significantly extend the life of the bearing, reduce maintenance requirements, and enhance the efficiency of the mechanical system. Proper lubrication practices are crucial for the optimal performance of bushings and plain bearings.

    Bushings and bearings play a critical role in mechanical systems, offering a wear-resistant interface between two components. The choice of material and construction for the bushing often determines its lubrication requirements. Let’s delve into the lubrication needs and characteristics of the various bushing types you mentioned:

    1. Solid Bronze Bushings:

    • Material: Pure bronze or phosphor bronze.
    • Lubrication: Typically, these bushings require external lubrication. Oil or grease is used to reduce friction and wear. Periodic re-lubrication is necessary, especially in high-load or high-speed applications.

    2. Sintered Bronze Bushings:

    • Material: Porous bronze material produced through a powder metallurgy process.
    • Lubrication: These bushings are often impregnated with oil during the manufacturing process. The porous structure allows the oil to be released slowly during operation, providing self-lubrication. However, in some cases, periodic re-lubrication might be necessary, especially in demanding environments.

    3. Wrapped Bronze Bushings:

    • Material: Thin sheets of bronze, often with indentations or holes, wrapped into cylindrical shapes.
    • Lubrication: The surface indentations or holes typically act as lubrication reservoirs. These bushings may come pre-lubricated or might require initial lubrication. The lubrication reservoirs help extend re-lubrication intervals, but periodic maintenance is still needed in most applications.

    4. PTFE Composite Bearings:

    • Material: Metal-backed with a layer of PTFE (Polytetrafluoroethylene) composite material.
    • Lubrication: These are self-lubricating bearings. The PTFE layer offers a low friction surface, eliminating the need for additional lubrication. They are ideal for applications where maintenance is challenging or where contamination from external lubricants is a concern.

    5. POM Composite Bearings:

    • Material: Metal-backed with a layer of POM (Polyoxymethylene) composite material.
    • Lubrication: POM composite bearings often have lubrication pockets filled with grease. While the POM layer provides some inherent lubrication, the grease reservoirs further enhance the bearing’s low-friction properties. Depending on the application, they might require occasional re-lubrication.

    In Summary:

    • Solid and Wrapped Bronze Bushings: Typically require external lubrication, either initially or periodically.
    • Sintered Bronze Bushings: Offer self-lubrication due to oil impregnation but might need occasional re-lubrication.
    • PTFE and POM Composite Bearings: Generally self-lubricating, with PTFE bearings rarely requiring external lubrication and POM bearings possibly needing occasional re-lubrication.

    The choice of bushing and its lubrication regime will depend on the specific application, operating conditions, and maintenance capabilities. Proper lubrication practices will ensure optimal performance and extended life for the bushing.
