running without the outer stub will destroy the bearing in very short order.

These are double roller ball bearing and do not rely on the outer nut to preload the bearing rather just to full seat the bearing and hold it in place using the solid center portion of the bearing. The only failure that would happen is the whole bearing coming off the hub if there was no nut/axle.
