Ah ok. You're understanding them correctly but I don't think that would be best, assuming you're using aluminum or plastic pulleys. I've already mentioned aluminum is a horrible bearing material and it would be much better to have the shaft steel than the pulley. Having the bushing rotate on the shaft would also mean lower surface speeds, less wear and less friction and be stiffer.
