In this paper, the reduction effect of dry (solid) lubrication on wheel flange wear rates is studied. The solid / dry lubricator systems were attached to the most front and furthest back axles of a coach in order to examine the wear behavior of the equipped wheels. An attempt is also made to make a comparison between wear behaviors of these wheel flanges having dry lubrication devices with non-lubricated wheels in other railcars. Finally, a comparison is made between life-cycle of wheels under investigation and other similar wheel types.
