Well, to picture it just picture a 3" tube with nothing in it, the bearings sit on both sides and the only thing stopping them from sliding inward is the snap rings or the lip (depending on the type of bearing). The only thing stopping them from moving out is the spindle bolt, and like MSM said if you tighten that bolt down to much you'll either break the snap ring, or push the inner ring of the bearing out of place creating lots of play.
The spacer on the inside will allow us to tighten the bolt down a lot more and it will put the pressure on the inner rings but they wont move, and now they should last longer.
these are the hubs I have and the bearings that came with them in the pic ... http://www.*************/item/Heavy-D...ub-260056-3203
you can see the inner ring how it protrudes, after a bit of riding that inner ring gets very loose, and the spindle bolt gets closer and closer to the bearing until you have to tighten it down and its basically riding and grinding on the outside of the bearing. wall and not the inner ring. Hope that explains it a little.
