1. A friction bearing of a planetary gearbox, comprising:
a rotationally fixed first component and a second component rotatably connected thereto,
an oil feed pocket positioned on the first component and configured to direct oil into a bearing clearance between the first and second components,
a first port connected to a first line opening into the oil feed pocket, and configured for directing the oil into the oil feed pocket,
wherein the first line is oriented such that the oil is directed from the first line into the oil feed pocket at an angle of approximately 5° to 60° in relation to a radial direction of the bearing clearance and in a rotation direction of the second component in relation to the first component.
