1. A hydrodynamic bearing system comprising:
a sleeve assembly including:
a sleeve body; and
a cross-member fluidically dividing an interior of the sleeve body into a first interior cavity and a second interior cavity, the cross-member extending across the interior of the sleeve body;
a first shaft positioned in the first interior cavity;
a second shaft positioned in the second interior cavity;
a first journal bearing including a first fluid interface surrounding at least a portion of the first shaft and configured to support radial loads; and
a second journal bearing including a second fluid interface surrounding at least a portion of the second shaft and configured to support radial loads.
 
14. A method for operation of a hydrodynamic bearing system, comprising:
rotating a sleeve assembly;
where the sleeve assembly includes:
a sleeve body; and
a cross-member fluidically dividing an interior of the sleeve body into a first interior cavity and a second interior cavity, the cross-member extending across the interior of the sleeve body;
where a first shaft is positioned in the first interior cavity;
where a second shaft is positioned in the second interior cavity; and
where the hydrodynamic bearing system includes:
a first journal bearing including a first fluid interface surrounding a portion of the first shaft and configured to support radial loads; and
a second journal bearing including a second fluid interface surrounding a portion of the second shaft and configured to support radial loads.
