The ball bearings work by riding around against the race. With the cup not holding them against the race they are all over the place. Allow a big enough gap and instead of chasing each other they'll start doubling up, allowing the spindle to to twist down

There's a good chance that the ball bearings in my bottom bracket will be caged bearings. I have done some research by myself. My Schwinn World Sport's bottom bracket parts will more or less look like the five parts on the left side of the spindle (plus the dust shield, which is missing in the picture posted below).
