Abstract

A bearing alignment assembly comprises an outer ring. An inner ring assembly is disposed radially inwardly of the outer ring and cooperating therewith to form a roller volume. The inner ring assembly has a forward inner ring and an adjacent aft inner ring cooperating to provide an inner surface of the inner ring assembly. The forward inner ring includes axial grooves extending axially along and circumferentially spaced around a forward portion of the inner circumferential surface of the inner ring assembly. One or more of the axial grooves of the forward inner ring being an alignment axial groove having at least one cross-sectional dimension different than a corresponding cross-sectional dimension of other of the axial grooves of the forward inner ring, the aft inner ring including axial grooves extending axially along and circumferentially spaced around an aft portion of the inner circumferential surface, at least one of the axial grooves of the aft inner ring having the different cross-sectional dimension and positioned on the aft inner ring for alignment with the alignment axial groove. Rolling elements are rollingly disposed in the roller volume for relative rotational motion o…
