I would have used a bigger torch (cutting tip like Trav mentioned) or- I have found that with REALLY stuck things that an air hammer or press won't budge, a REALLY big hammer will almost always work. In this case here, I may have put everything on a steel plate on the floor, lined all the parts up perfectly and given it a massive smack with a sledge. Done properly, the massive force will go directly to breaking the rust bond loose and pushing the bearing down a fuzz. You can then either finish with the press for a more controlled removal or continue to work your aggression out with the sledge.
I didn't find the right solution from the Internet.
