Summary:An integrated bearing assembly is provided, comprising a bearing housing defining an axial cavity in which a shaft is disposed. The shaft is rotatably supported by at least two bearing sets. The axial cavity defines three regions, each having distinct diameters. A pair of first regions defines cavity diameters sufficient to receive the bearing sets. A pair of second regions defines cavity diameters such that a small gap is defined between the inner surface of the cavity and the shaft. The third region cooperates with the shaft to define a cylindrical volume containing a coolant. Wettable coatings are utilized in the cylindrical volume to allow free flow of, and maximum contact with, the coolant. Non-wettable coatings are provided in the second regions to contain the coolant. The second regions also function as bearing spacers, thus simplifying bearing assembly design, assembly, and performance.
