You will be able to get the seal out without damaging the bearing with a little persistence and creativity, even without special tools.
Worst case, you can (carefully) chisel all the way through the seal's outer metal ring to release the pressure, or drive it towards the center until it "relents". Just be careful. You can use a brass punch or chisel if you want to be very safe, though this operation may distort the brass somewhat...
Best of luck.
