Abstract
The present invention provides, in one embodiment, a bearing assembly consisting of a rotatable shaft and a stator coaxially aligned. The stator has at least one circumferential protrusion that contains respective segments that extend radially from the stator. Each of the respective segments contains at least one capture cavity and has a main cavity disposed between each of the respective segments so as to house a thermal shunt. A plurality of roller bearings are also disposed radially between the rotatable shaft and the stator. In addition, at least one viscoseal is disposed on the rotatable shaft.
