Cut it off. That's what I had to do on my Streaker. If the angle grinder doesn't fit, use a Dremel with a cutting disk.
Try to back it off, with more force/momentum (bigger smacky thing), than what you are currently using. Force=Mass X Acceleration. So bigger mass, or more acceleration, or both. But make sure to go in the direction you put it on. I had to take off a little bit off my jackshaft with emery cloth for this exact reason. My dia measured out to about 1.004-1.008 in a few spots. Likely your bearing is dead on 1.000" And your jackshaft/whatever shaft, is simply a little big. If you have calipers, give it a shot, you will see what I am talking about.
You could also try using a car/vehicle jack, to achieve your goal. Basically a mini 2 ton press if you have something strong to brace against.
DONE! FINALLY! I cut the pillow block assembly off first with an angle grinder and cutoff disk. I ended up breaking the outer race away delicately (8 lbs sledge) then gracefully removing the bearings and container (sledge again) but had trouble with the delicate method of hammering away at the inner race. I ended up cutting a notch in it down to almost the axle, then hammering a cold chisel to expand the ring and slide it off. It was completely rusted on thank you everyone who helped. I got a replacement bearing assembly for 15.95$ (plus 7$ shipping) here: Pillow Block Assembly | 3013-2806 | BMI Karts and Parts
