A plate bearing of a bridge shoe is provided to prevent uneven abrasion by exposing and dispersing solid lubricant on a surface contacted between a plate bearing and an upper shoe or a lower shoe. A plate bearing of a bridge shoe comprises a sintering layer formed by spreading mixed powder(9,11) of stainless metal power and solid lubricant powder on upper and lower surfaces of a steel base material(7) formed in a circular plate whose upper surface is flat and lower surface is convex. The sintering layer is sintered and pressed by a pressing unit inside molds(13,15). |
