A turbocharger (102, 202, 302) including a rotating assembly (114, 214, 314) having a compressor wheel (120, 220, 320) and a turbine wheel (110, 210, 310) mounted on opposite ends of a shaft (112, 212, 312). A bearing housing (160, 260, 360) supports the rotating assembly (114, 214, 314) and comprises at least two segments (189, 190; 289, 290; 389, 390). Each segment (189, 190; 289, 290; 389, 390) has an opening large enough to radially receive the rotating assembly (114, 214, 314). The bearing housing segments (189, 190; 289, 290; 389, 390) are fastened (193) together and a flexible seal may be provided between the segments. The bearing housing (160, 260, 360) may house rolling element bearings (325) or journal bearings (149), for example. The bearing housing (160, 260, 360) is split axially (101, 201, 301) into an upper segment (189, 289, 389) and a lower segment (190, 290, 390). Alternatively, the bearing housing (160, 260, 360) is split axially (101, 201, 301) into a left segment and a right segment. The
