If you're adjusting preload on radial bearings, this is what's happening. As I said, it's a nasty kludge. If your cartridge bearing hub has preload adjustment, IMO the bearings should be AC.
Consider the angle between contact points on the races on a sloppy radial bearing that's had the rattle adjusted out. It's nasty.
