need help with the wheel hub

[flamaster]

hello, sorry for writing in English but I'm not German. I just bought MZ RT 125/2 '58 for renovation, and I have a problem that I guess only such forum can help

I am trying to take out the bearing from the hub, but I have no idea how to do that. There are no spaces for wrench and it does not move with the use of a hammer. Please see the image.

Any ideas?

Thanks!
