Development of the aluminum alloy bearing with higher wear resistance

The recent demands for higher performance and lower fuel consumption of automotive engines require the bearings to operate under severe conditions. As a result of these requirements, engine bearings are used under higher unit loads and higher temperatures, where the oil film thickness between bearing and shaft is increasingly thinner. One of the problems with conventional aluminum alloy bearings used under these conditions is the low wear resistance. For this reason, we have developed a new aluminum alloy bearing that allows a higher wear resistance. This paper describes the mechanism to upgrade the wear resistance and the performance of this new bearing material.
