Abstract: Liquid metal bearing assemblies and methods for operation of said assemblies are provided. One example liquid metal bearing assembly includes a liquid metal interface positioned between a stationary component and a rotational component. The rotational component includes a liquid metal reservoir configured to contain a liquid metal and positioned radially inward from the liquid metal interface, a liquid metal passage extending between the liquid metal reservoir and the liquid metal interface, and an anti-wetting surface in the liquid metal passage.

Abstract: Systems and methods related to hydrodynamic bearings are provided. One example hydrodynamic bearing system includes a sleeve assembly including a cross-member fluidically dividing a first interior cavity from a second interior cavity, a first shaft positioned in the first interior cavity, and a second shaft positioned in the second interior cavity. The hydrodynamic bearing system further includes a first journal bearing including a first fluid interface surrounding at least a portion of the first cantilever 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 cantilever shaft and configured to support radial loads.

Abstract: Systems and methods related to hydrodynamic bearings are provided. One example system includes a hydrodynamic bearing including a rotational component configured to attach to an anode and a stationary component. The stationary component includes a bearing surface having a plurality of grooves configured to generate pressure in a fluid interface during rotation of the rotational component and where the bearing surface includes at least one recessed section profiled based on an expected pattern of wear.
