An assembly comprising: a turbocharger center housing that comprises a bore wall that defines a bore having a bore axis, an upper recess and a lower recess that, in conjunction with a semi-floating bearing disposed in the bore form an upper chamber and a lower chamber, respectively, the lower chamber adjacent to a lubricant outlet; the bearing disposed in the bore wherein the bearing comprises a central bore for receipt of a turbocharger shaft, a first outer section that comprises an end, a journal for the turbocharger shaft, an annular channel, openings in the annular channel for flow of lubricant to the journal, and, disposed axially between the annular channel and the end, an annular notch, and a second outer section that comprises an end, a journal for the turbocharger shaft, an annular channel, openings in the annular channel for flow of lubricant to the journal, and, disposed axially between the annular channel and the end, an annular notch; a first substantially planar spring having a substantially sinusoidal shape and free standing inner and outer diameters (250, 450, 550) disposed at least partially in the annular notch of the first outer section and in contact with the bore wall of the housing and the bearing to hinder axial flow of lubricant to the end of the first outer section of the bearing and to bias the bearing, while supporting the turbocharger shaft, toward the bore to maintain a more even squeeze film thickness between the bearing and the housing; and a second substantially planar spring having a substantially sinusoidal shape and free standing inner and outer diameters (250', 450, 550) disposed at least partially in the annular notch of the second outer section and in contact with the bore wall of the housing and the bearing to hinder axial flow of lubricant to the end of the second outer section of the bearing and to bias the bearing, while supporting the turbocharger shaft, toward the bore axis. a turbocharger center housing that comprises a bore wall that defines a bore having a bore axis, an upper recess and a lower recess that, in conjunction with a semi-floating bearing disposed in the bore form an upper chamber and a lower chamber, respectively, the lower chamber adjacent to a lubricant outlet; the bearing disposed in the bore wherein the bearing comprises a central bore for receipt of a turbocharger shaft, a first outer section that comprises an end, a journal for the turbocharger shaft, an annular channel, openings in the annular channel for flow of lubricant to the journal, and, disposed axially between the annular channel and the end, an annular notch, and a second outer section that comprises an end, a journal for the turbocharger shaft, an annular channel, openings in the annular channel for flow of lubricant to the journal, and, disposed axially between the annular channel and the end, an annular notch; a central bore for receipt of a turbocharger shaft, a first outer section that comprises an end, a journal for the turbocharger shaft, an annular channel, openings in the annular channel for flow of lubricant to the journal, and, disposed axially between the annular channel and the end, an annular notch, and a second outer section that comprises an end, a journal for the turbocharger shaft, an annular channel, openings in the annular channel for flow of lubricant to the journal, and, disposed axially between the annular channel and the end, an annular notch; a first substantially planar spring having a substantially sinusoidal shape and free standing inner and outer diameters (250, 450, 550) disposed at least partially in the annular notch of the first outer section and in contact with the bore wall of the housing and the bearing to hinder axial flow of lubricant to the end of the first outer section of the bearing and to bias the bearing, while supporting the turbocharger shaft, toward the bore to maintain a more even squeeze film thickness between the bearing and the housing; and a second substantially planar spring having a substantially sinusoidal shape and free standing inner and outer diameters (250', 450, 550) disposed at least partially in the annular notch of the second outer section and in contact with the bore wall of the housing and the bearing to hinder axial flow of lubricant to the end of the second outer section of the bearing and to bias the bearing, while supporting the turbocharger shaft, toward the bore axis.
