ballnut housing and floating end ballscrew assembly

Thank you gents, this is exactly why I've asked the question, I've never thought about it to be honest.

One more question regarding the fitting of the 'barrel' of the ballnut inside the housing. Normally the non-flange part of the ballnut is marked as 'g6' tolerance and if I'm not mistaken it's a slide fit in the housing. Any reason for this other than space saving and making the bore in the housing an almost exact fit? I'm asking because the mounting holes on the flange are 4.5mm dia, which means there's some wiggle room to align the ballnut with the ballscrew, but of course in order for that to be possible, the bore for the body of the ballnut needs to be slightly bigger than g6.
