    摘要： A bearing device includes: a bearing housing; a floating metal having a cylindrical shape and disposed in a housing hole of the bearing housing and in which a rotational shaft is inserted; and a positioning pin for positioning the floating metal with respect to the bearing housing, the positioning pin being disposed along a radial direction of the rotational shaft. The positioning pin includes a first oil supply hole formed so as to penetrate the positioning pin and communicating with a first space between an inner peripheral surface of the floating metal and an outer peripheral surface of the rotational shaft, and a second oil supply hole formed inside the positioning pin so as to connect a second space to the first oil supply hole, the second space being disposed between an outer peripheral surface of the floating metal and an inner peripheral surface of the housing hole.

    摘要： A turbocharger assembly can include a shaft having a rotational axis where the shaft includes a turbine wheel that includes a hub portion; a bearing that includes an outer race, an inner race operatively coupled to the shaft, and rolling elements disposed between the inner race and the outer race where an inner radius of the outer race and an outer radius of the inner race define a radial gap; and a lubricant slinger disposed axially between the inner race and the hub portion of the turbine wheel where the lubricant slinger includes a surface that faces and slopes away from the radial gap.
