Lifespan Requirements: How long the bearing is expected to last. Harder materials tend to have longer lifespans.
Lubrication: Some bronze materials are better suited to certain types of lubrication, or can be used in oil-less applications.
Therefore, selection of a bearing material is a complex process that involves considering the specific needs of the application, the material’s properties, and cost-effectiveness. Consulting with a materials engineer or a reliable supplier can help guide this process.
Which bronze alloy is commonly used as bearing alloy?
Leaded Tin Bronze, often referred to as “leaded bronze”, is commonly used for bearings because it offers an excellent balance of performance and cost-effectiveness. The tin increases the strength and corrosion resistance of the bronze, while the lead improves its ability to embed small particles of dirt or debris, which can help protect the bearing and the shaft it rides on from damage. This ability to embed dirt, combined with the alloy’s excellent anti-friction properties, makes it an excellent choice for bearings.
Leaded tin bronze alloys are often used in moderately loaded applications where the speeds are high. Common applications include automotive bearings, pumps, and cylinders.
Another alloy that’s worth mentioning is Aluminum Bronze. This alloy, particularly the variety that also includes a small amount of nickel, is a very high-strength bronze that’s used for heavy-duty bearings and other components that have to carry high loads.
Finally, it’s worth noting that while bronze alloys are very popular for bearings, other copper alloys like brass are also sometimes used, particularly in applications where resistance to corrosion is very important.
As always, the exact alloy to use depends on the specific requirements of the application, including the load, speed, and operating environment. Consultation with a materials engineer or a reliable supplier can help guide this selection process.
