A method of forming a bearing having a body of sintered powder metal. The bearing body includes a plurality of surfaces with interstices in the sintered powder metal defining a plurality of lubricant flow capillary paths through the bearing body communicating with the surfaces thereof, respectively. In this method, at least some of the sintered powder metal of at least one of the surfaces on the bearing body is mechanically worked with respect to the capillary paths communicating with the at least one surface, and the capillary paths communicating with the at least one surface are thereby at least restricted to a preselected degree limiting the porosity thereof generally at the at least one surface. |
