You are a vacuum expert, so I apologize if these ideas are not new to you. 🙂
I have something very similar to the item in the link below. In general, it works well for removing ball bearings which have been pressed on to vacuum armatures. Perhaps get one of these in the right size? The right press might also work. Note: if you go this route, be absolutely sure that you replace the original bearing with a high speed electric motor grade bearing. Not all sealed bearings are created equal, and you don’t want to mistakenly install a bearing intended for a skateboard. Your other option is to pop at least one of the seals off and clean/degrease the bearing without ever removing it from the shaft. More often than not, I actually do this trick since it is the least “invasive.” A fine-tipped syringe is perfect for injecting Mobil 1 Polyrex EM into the bearing. Good luck! | ||

I see. Thin custom made plates and a press might do the trick. A local machinist should be able to get it off without too much effort.
Honestly, though, I would just service the bearing with it on the armature shaft. It sounds like you can take the upper seal off, assuming it isn’t a shielded bearing. After that, a good cleaning and re-greasing should pump a good bit more life into the bearing. | ||

Yeah, a local machinist would probably be your best choice. Unless you want to try making a tool yourself. Or just googling 'bearing puller' until you find something that looks right. The link below is one tool I found that might be suitable. A picture of the bearing to be pulled would help.
You could also just buy a cheap bearing puller and grind away the claws until they fit in the recess. CLICK HERE TO GO TO MadMan's LINK | ||
