Personal experience.

Fanuc robots are straight forward to service, they make the parts very available to do it yourself if you want. We order them here and there no problem.

But they are beasts and it can take an entire day just to replace a part. Then you have to reassemble it in the right order. None of it is made difficult on purpose. It has tight tolerances, and fancy shit like harmonic drives for zero backlash and more.

I don't know. I remember trying to get lower level servo metrics out of Fanuc arms into a historian and they laughed and said they had their own preventative maintenance service I could sign up for; but they wouldn't expose the same info to me to use.
