Another way to do it is to take a piece of flat stock that will fit the through the ID of the race you want to pull and about 1/8 to 3/16 thick. Cut the stock a little longer than the bearing race inner diameter, and grind the ends on an arc that is the same as the ID of the race you want to pull. Repeat for the opposite end of the flat stock and make a trial fit. If it is too long to lay squarely in the race, grind the arc on one end a bit until it just slides into place.
Find the center and drill and tap it for a 3/8 or equivalent fine thread. Thread a piece of allthread through the tapped hole, back it with a nut to jam it in place. Repeat with a bridge over the top of the bearing and another nut and washer. Tighten the nut until the race pulls free. If it is stubborn, warm with a heat gun or blow dryer.
I've pulled Timken tapered roller bearing cups the same way, using thicker stock. Works every time.
