I'm guesing it's paint and rust that are your enemy here. I work at a machine shop, and we NEVER heat a bearing, doesn't matter what kind it is, just bad practice far as we're concerned. I'd polish the shaft first, that does the trick 99.9% of the time, the other .1% the bearing is junk and needs to be replaced. Bearings are made to slide with no clearance on the shaft, so any nicks, burrs, rust or paint will cause it to bind. The shaft has to be smooth. Could even have a machine shop put it in a lathe and polish it. It'll only take a minute and they'll MAYBE charge you $5, unless you are friends or a good customer, then they'll shrug and say "don't worry about it"

Once in a while we make a shaft to press fit into the ID of a bearing, but that is few and far between and something that fits in a press with ease.
