Abstract
An exemplary gas turbine engine includes a radially stacked intershaft bearing assembly. The assembly includes an outer stubshaft having outer and inner diameter surface portions disposed concentrically with respect to one another. The outer diameter surface portion is rotatably connected to a body of the engine, and the inner diameter surface portion is rotatably connected to an inner stubshaft of the engine, so as to provide a stacked configuration of the inner stubshaft, the outer stubshaft, and the body along a radial direction orthogonal to a longitudinal axis of the engine.
