Abstract
A rotor is surrounded by a stator. A radial bearing includes a first radial bearing portion coupled to the rotor and a second radial bearing portion coupled to the stator. A thrust-bearing includes a first portion coupled to the rotor. The first portion is spaced from a second portion coupled to the stator defining a first annular fluid gap in-between that is in fluid communication with an outside environment exterior the downhole-type machine. The thrust bearing is configured to support an axial load of the rotor within the stator.
