Sealed bearings are the same tapered roller bearings as non-sealed bearings, just not serviceable. They typically go 100k or so before replacement so that gives you an idea how far serviceable bearings will probably go if you never touch them. BTW, I have pressed a set of sealed bearings apart and there wasn't very much grease inside.

My cheap junk Chinese bearings were spent in 8,000 miles. Actually because one was ground so poorly, it started the failure process on the first revolution. YMMV
