Alloy Selection
Oversided Bronze Bearings- Alloy Selection
The choice of a bronze alloy for a particular application is determined by the desired physical, mechanical, and metallurgical properties needed. Selecting a suitable alloy depends on a variety of factors. Proper alloy selection is necessary to obtain maximum resistance to wear and corrosion and a long service life.
Bronze Alloys
Below are some of the most common alloys used for oversized bronze bearings. The properties listed are based on centrifugally cast bronze. This chart is for information only and should not be used for design purposes.
Leaded Tin Bronze Alloys
These alloys are generally more widely available than other bronze alloys and less expensive also. The Leaded Tin Bronze Alloys will tolerate slight shaft misalignments and are known for their performance against steel journals. Their unique properties alloy them to be used against and unharded shaft as well as shafts that are not perfectly smooth.
