Is there a chart showing the fittings or are they all sealed?

Grease fittings? What do you think this is, a '56 Studebaker? No grease fittings. You'll have to hand up your gun.

Yep most all bearings are sealed, life time is what they call them. That means they will fail in your life time and will need replacement. There is absolutely no reason they could not be made more serviceable. Even sealed bearings can be serviced, just more difficult.
