Abstract

An oil bearing to support a rotor of a turbine, especially of a gas turbine, wherein the rotor extends along a rotor axis coinciding with a bearing axis, has at least one oil bearing pad being lubricated by oil, including an oil sump suitable and located to collect the oil from the bearing pads by forces of gravity, including a drain system of the oil sump to conduct the oil away from the oil sump. The drain system includes at least three drain openings of the oil sump, wherein a first drain opening joining a first drain line is located between 4 o'clock and 5 o'clock according to the bearing axis, wherein a second drain opening joining a second drain line is located between 5:30 and 6:30, wherein a third drain opening joining a third drain line is located between 7 o'clock and 8 o'clock.
