The problem isn't the lack of concentricity, the outer casing isn't spinning so it doesn't matter. What does matter is the very loose tolerance (only max is stated, not an actual tolerance) on the outside diameter that you're clamping onto. If you assume nominal is 2.5" and max is +36 thou thats quite a large tolerance. However if you were to measure all of your cims and find them all to be the same then you could probably get away with it and be fine.
EDIT: ok concentricity kind of matters but becomes kind of irrelevant once you clamp the motor down. And lack of it could even be used to adjust the center distance to correct it.
