Yes and no. It's not meant to happen, but if you determine that it must happen, it can be done. If you insist on prying it apart, and don't have a great approach, and remain determined to do it anyway, it's definitely possible to destroy stuff.
to first order, move the bearing in your fingers, one ring rotating against the other. If it feels smooth rather than rough, that's good. If you feel viscosity rather than dryness, that's also good. Don't try to take it apart. If either of those things feels unacceptably bad to you, then maybe you want to take it apart. If you think you want to take it apart because you think it's good preventative maintenance, or you think it must be in need of an overhaul, then don't bother. That's my advice. I took apart a Deore LX model with similar architecture. One of the bearing units was pretty rusty and I did pull it apart, cleaned things out, added new balls, and pressed it back together. That's how I know it is possible. If your bearings are as hosed as mine were, give it a go. If you think they seem fine, they probably are.
