Here's another handy hint from my days at sea discussing business with the Chief Engineer:

To remove bearing cups in places inaccessable to pullers:

Fire up your welder, be it stick or mig and put one bead of weld on one side of the cup only. This causes the cup to deform inwards when it cools and the cup will practically drop out.
We changed hundreds of conveyor roller cups this way and I can vouch that it worked perfectly on removing the inner bearing races of my CMP truck diffs.

Hope you find this interesting and helpful.

Best Regards
