A journal bearing is disclosed with shoe segments. Each shoe segment has a supply groove for even distribution of oil across the shoe surface during shaft rotation. The supply grooves have bleed vents that relieve pressure build-up in the supply groove by bleeding oil out of the supply groove in a substantially circumferential direction. Directing oil in this way prevents the pressurized oil from impinging on any nearby seals and provides enhanced temperature profile characteristics.

A shoe segment for a journal bearing comprising: a leading edge; a bearing surface for supporting a rotating shaft; a supply groove recessed into the bearing surface; and, at least one bleed vent extending from said supply groove to the leading edge of the shoe segment such that oil entering the supply groove can bleed through the leading edge in a circumferential path substantially perpendicular to the leading edge and perpendicular to the axis of rotation of the rotating shaft.
