The friction reducing capacity of the Plain Shaft Bearing is based upon the phenomenon that similar materials slide against each other with less wear and friction than dissimilar materials. Thus, alloys of such metals as copper, tin or lead do a better job of supporting a steel moving part than would a companion housing of steel or even cast iron. |
