I can't extract sealed bearings out of hub
I haven't done this one in particular, but here are some things that may be applicable:


The spacer between the two bearings may be a tubular spacer that with the axle out is simply held in place by friction. If so, with some persuasion you can nudge to one side, allowing you to hit the outer bearing with a punch from the inside out.
The inner bearing may be held in place with a circlip you presently can't see, keeping what you're trying to do now from working. It's been a while but I believe this is how Campy freehubs are put together.
An expanding collet type bearing extractor looks like it could work here. Here are the ones made by Wheels Mfg. The whole kit is expensive but individual ones are pretty reasonable. You'd do the outer bearing first and see what that uncovers once it's out.
