The rigidity and concentrically advantage over most 2 piece blocks (as most 2 piece blocks don't adequately align to each other) is nice as well.

You don't even need bearing blocks-- The robonauts didn't use any this year, they just pressed their bearings straight into the frame rail.

As time goes on, our drives get more and more interesting. We started with cantilevered wheels, then aluminum sprockets and shafts, and now, we're starting to ditch the bearing blocks.
