A wear and lubricating liner having a cup-shaped wear liner assembly (20) which includes a first bottom plate portion (16). An aperture (18) is formed centrally through such first bottom plate (16) and a first upstanding wall portion (22) is connected at a bottom thereof to an outer perimeter of such first bottom plate (16). A lubricating liner assembly (30) having at least one substantially solid lubricating material (24) 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 (26). 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 (20). A protective cover member (40) includes a second bottom plate portion (28) having a bottom surface disposed adjacent and in contact with an upper surface of such at least one solid lubricating material. Another aperture (32) is formed centrally through such second bottom plate. A second upstanding wall portion (34), located on the protective cover (40), is connected at a bottom thereof to an outer perimeter of such second bottom plate (28) and an annular lip-like portion (36) is connected adjacent an inner edge thereof to an upper edge of such second upstanding wall (34). Such lip-like portion (36) extends outwardly from such upper edge of the second upstanding wall and downwardly toward a top surface of such bolster bowl. A space (38) is disposed between an inner surface of such ring-like lubricating material and an outer surface of such second upstanding wall. <IMAGE>
