Basic Characteristics of Lead-free Aluminum Alloy Bearings with Low Frictional Property of Adhered Molybdenum Disulfide 2007-01-1570

A newly developed bearing is a lead-free aluminum alloy bearing with low frictional layer which consists of molybdenum disulfide in thicknesses of sub-micron levels on the bearing surface without required binders such as resin. The new bearing had a 50% lower static friction coefficient compared to the conventional aluminum alloy bearing, and exhibited comparable anti-seizure property and fatigue strength to the conventional bearing by evaluation of rig tests. These rig tests verified that the new bearing showed excellent frictional reduction properties. This paper describes details and performances of this newly developed bearing.
