Below are some self-lubrication options for bronze bearings, along with relevant ASTM and EN standards:
Self-Lubrication Options for Bronze Bearings
-
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).
-
-
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).
-
-
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.
-
-
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.

-
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.
