A wear and lubricating liner having a cup-shaped wear liner assembly which includes a first bottom plate portion. An aperture is formed centrally through such first bottom plate and a first upstanding wall portion is connected at a bottom thereof to an outer perimeter of such first bottom plate. A lubricating liner assembly having at least one substantially solid lubricating material with a bottom surface thereof disposed adjacent and in contact with an upper surface of such bottom plate and a vertically disposed ring-like solid lubricating material. An outer surface of such ring-like lubricating material is disposed adjacent and in contact with an inner surface of such upstanding wall of the wear liner. A protective cover member includes a second bottom plate portion having a bottom surface disposed adjacent and in contact with an upper surface of such at least one solid lubricating material. Another aperture is formed centrally through such second bottom plate. A second upstanding wall portion, located on the protective cover, is connected at a bottom thereof to an outer perimeter of such second bottom plate and an annular lip-like portion is connected adjacent an inner edge thereof to an upper edge of such second upstanding wall. Such lip-like portion extends outwardly from such upper edge of the second upstanding wall and downwardly toward a top surface of such bolster bowl. A space is disposed between an inner surface of such ring-like lubricating material and an outer surface of such second upstanding wall.

An aperture is formed centrally through such first bottom plate and a first upstanding wall portion is connected at a bottom thereof to an outer perimeter of such first bottom plate. A lubricating liner assembly has a plurality of substantially solid lubricating material pieces each having a bottom surface disposed adjacent and in contact with an upper surface of such bottom plate and a vertically disposed ring-like solid lubricating material. An outer surface of such ring-like lubricating material is disposed adjacent and in contact with an inner surface of such upstanding wall of the wear liner. A protective cover member includes a second bottom plate portion having a bottom surface disposed adjacent and in contact with an upper surface of each piece of solid lubricating material. Another aperture is formed centrally through such second bottom plate. A second upstanding wall portion, located on the protective cover, is connected at a bottom thereof to an outer perimeter of such second bottom plate and an annular lip-like portion is connected adjacent an inner edge thereof to an upper edge of such second upstanding wall.
