Claim 10:
11. A method of manufacturing a self-lubricated sliding bearing, comprising:
providing a first bearing member;
providing a second bearing member configured to concentrically enclose a portion of the first bearing member;
forming a cooperating surface of the second bearing member or the first bearing member comprising a first region comprising a pumping pattern configured to pump a lubricant;
forming a cooperating surface of the second bearing member or the first bearing member comprising a second region having a modified pumping pattern or a smooth surface, wherein the second region is disposed on the cooperating surface of the second bearing member or the first bearing member, such that a bearing force generated by the pumping action of the lubricant opposes a radial load force exerted on the self-lubricated sliding bearing to reduce an eccentricity of a longitudinal axis of the first bearing member with respect to a longitudinal axis of the second bearing member;
introducing a lubricant into a gap between the first and second bearing members; and
sealing the first and second bearing members, wherein the modified pumping pattern comprises a surface having a groove depth and/or width that becomes continuously shallower around a circumferential length compared to the groove depth and/or width of the pumping pattern of the first region.
