Patent ID: 8375587

Claim:
A method comprising: providing a journal bearing blank that comprises an axis, an inner surface disposed at an inner diameter, an outer surface disposed at an outer diameter, a first axial surface, a second, opposing axial surface, and a lubricant opening that extends between the inner surface and the outer surface; along the inner surface, milling a well that connects to the lubricant opening and that spans an azimuthal angle about the axis wherein the well comprises a well depth; along the inner surface, milling an arm that spans an azimuthal angle about the axis and that extends from the well to the first axial surface of the journal bearing wherein the well depth exceeds an arm depth at the first axial surface; along the inner surface, milling an opposing arm that spans an azimuthal angle about the axis and that extends from the well to the second axial surface of the journal bearing wherein the well depth exceeds an arm depth at the second axial surface; and inserting the journal bearing in a bore of a turbocharger center housing.
