The Bronze Age ended 2,600 years ago, so why does SelfLube still use bronze?

Good question. For components that are used to guide and control motion - such as bushings, gibs, wear strips, etc. - bronze is still the preferred material. Consider a steel shaft/steel bushing combination. Both are stronger than bronze, but they tend to gall and wear out quickly when used together. A bronze bushing avoids this. The reason is that bronze has, in addition to some natural lubricity, a property known as formability. If the assembled parts are not exactly aligned with the axis of motion, the bronze will slightly redistribute itself to bring about a better alignment. This small shift has a big effect. It reduces galling and wear, thereby greatly increasing service life. For its bronze products, SelfLube uses C954 aluminum bronze, the finest bearing grade bronze available.
