Default What are the spacers inside wheels for?

I just spent a relaxing 20 minutes mullering the old bearings out of my spare rear wheel today, and I got to wondering what the spacer in the wheel actually does, apart from making it hard to knock the bearings out... It's not weight bearing, it's not tightly fitted, it doesn't rotate with the wheel... But it must do something, right?
