Below are some self-lubrication options for bronze bearings, along with relevant ASTM and EN standards:

Self-Lubrication Options for Bronze Bearings

  1. Oil-Impregnated Bronze Bearings

    • These bearings are made from porous bronze material impregnated with lubricating oil.

    • During operation, the oil seeps out to provide continuous lubrication.

    • Common materials: SAE 841, SAE 863 (oil-impregnated bronze).

  2. Graphite-Embedded Bronze Bearings

    • Graphite is embedded in the bronze matrix to provide dry lubrication.

    • Ideal for high-temperature or low-maintenance applications.

    • Common materials: CDA 954 (Aluminum Bronze), CDA 932 (High-Lead Tin Bronze).

  3. PTFE-Coated Bronze Bearings

    • A layer of PTFE (polytetrafluoroethylene) is applied to the bearing surface to reduce friction.

    • Suitable for applications requiring low friction and high corrosion resistance.

  4. Solid Lubricant Additives

    • Solid lubricants like molybdenum disulfide (MoS₂) or tungsten disulfide (WS₂) can be added to the bronze alloy.

    • These additives enhance the self-lubricating properties of the bearing.

Bronze Standards for Bearings

ASTM Standards

  • ASTM B22: Standard Specification for Bronze Castings for Bridges and Turntables.

  • ASTM B271: Standard Specification for Copper-Base Alloy Centrifugal Castings.

  • ASTM B505/B505M: Standard Specification for Copper Alloy Continuous Castings.

  • ASTM B584: Standard Specification for Copper Alloy Sand Castings for General Applications.

EN Standards

  • EN 1982:2008: Copper and copper alloys – Ingots and castings.

    • This standard covers various copper alloys, including bronzes, used in casting applications.

    • Examples: CuSn10 (Tin Bronze), CuAl10Ni5Fe4 (Aluminum Bronze).

Common Bronze Alloys for Bearings

  1. Tin Bronzes (e.g., CDA 932, CDA 937)

    • High wear resistance and good machinability.

    • Often used in oil-impregnated bearings.

  2. Aluminum Bronzes (e.g., CDA 954, CDA 955)

    • Excellent strength and corrosion resistance.

    • Suitable for heavy-duty applications.

  3. Lead Bronzes (e.g., CDA 943, CDA 944)

    • High load capacity and good conformability.

    • Commonly used in automotive and industrial bearings.

Selection Considerations

  • Load and Speed: Choose the alloy and lubrication method based on the operating conditions.

  • Environment: Consider corrosion resistance and temperature requirements.

  • Maintenance: Self-lubricating bearings are ideal for applications where maintenance is difficult.

By selecting the appropriate bronze alloy and self-lubrication method, you can optimize the performance and lifespan of bronze bearings in your application.
