ABSTRACT:
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.
