Abstract: A fluid seal for sealing a gap region for rolling elements rotationally connecting a shaft and an outer structure of a rotating assembly. In embodiments described, the fluid seal includes an inner capillary seal and an outer capillary seal radially and axially spaced from the inner capillary seal. The inner and outer capillary seals are formed along a passageway having an axial portion and a radial portion formed along capillary surfaces of a fluid seal structure and opposed transverse and upright surfaces. In embodiments disclosed, the fluid seal structure includes a seal ring and cap or a seal plate structure. In another embodiment, a flange portion of the shaft forms the fluid seal structure.
