One embodiment of a hub feed oil system is used to provide oil to components on the rotating side of an aircraft rotor hub system. A pump is configured so that a portion of the pump rotates with the rotating portion of the rotor system and a portion of the pump is fixed relative to the static portion of the rotor system. Multiple oil channels—with the provision of a variety of different pressures—may be provided.
