An electro mechanical-drive system includes a main shaft, a plurality of ball bearings disposed around the main shaft, and a plurality of roller bearing disposed around the main shaft. At least one of the ball bearings is aligned with at least one of the roller bearings along an axis perpendicular to the main shaft. The ball and roller bearings may support other components of the electro-mechanical drive system and may be arranged in a nested or staggered configuration.
