Abstract: A spacer (100 for a helicopter main rotor shaft (102) is mounted in combination with the main rotor shaft (102) and is operative to support the inner race (116) of the upper bearing assembly (110) of the main rotor shaft (102) and is concomitantly operative to restrain axial migration of the inner race (116). One preferred embodiment of the spacer (10) comprises a body member (11) having a stepped configuration defined by an upper cylindrical segment (12) and a lower cylindrical segment (20) to accommodate the outer structural envelope of the main rotor shaft (102). Structural continuity between the upper and lower cylindrical segments (12, 20) is provided by a lower annular collar (18) and an interface annular collar (22) and a plurality of reaction spokes (30) that extend between the upper annular collar (14) and the bottom annular collar (24).
