Porous sintered bearings are of a metal structure containing a multitude of pores that are connected with each other and also with the surface. The pore volume incorporated in the bearings varies from about 10 to 40 vol%. This pore volume serves as strage for a fluid lubricant with which the part has been impregnated during its manufacture. In most applications, the lubrication is produced within the bearing itself.
This report is containing an outline of sintered porous bearings and introductions of writer's researches on the bearings and then, some suggestions on the progress of the bearings, in conformity with the writer's research life for about fifty long years.
