A device is provided for the circulation of fluid through and about the rotary shaft of a rotating piece of equipment. The circulation is induced by a plurality of radially extending passageways from a center bore in the rotor shaft which extend to the external periphery of the shaft. Rotation causes the center of the shaft to be evacuated by pumping action created by the radial slots thereby producing a lowered pressure area producing a circulation path axially along the outside periphery of the shaft in one direction and axially along an internal through bore in the shaft towards the other end containing the radial slots. Bearings for mounting the shaft being disposed about the outer periphery of the shaft are thereby provided with lubrication and a cooling flow of fluids.
