A method of manufacturing an annular bearing housing for a gas turbine engine is provided that includes: producing a flange outer structure segment; producing an intermediate structure segment having an outer radial end, an inner radial end, a body that extends between the outer radial end and the inner radial end, and a branch member that extends outwardly from the body; producing a main body segment; attaching the flange outer structure segment to the outer radial end of the intermediate structure segment; and attaching the main body segment to the inner radial end of the intermediate structure segment. At least one of the flange outer structure segment, the intermediate structure segment, or the main body segment is produced using an additive manufacturing process.

A shaft assembly includes at least a first shaft section having a first shaft body defining a cavity and a first aperture extending through the first shaft body, and at least a second shaft section having a second shaft body and a second aperture extending through the second shaft body. The second shaft section is received within the cavity of the first shaft body, such that the second shaft body axially translates within the cavity relative to the first shaft section. An alignment component is formed in the at least first shaft section, the alignment component being a non-punctured alignment component. The second shaft body contacts the alignment component when the first aperture of the first shaft body is aligned with the second aperture of the second shaft body.
