"maybe lubed with graphite dust.'
Graphite is harmless to both the scale and powder. In fact, powder is mixed with a bit of graphite to help it flow better by the makers. The design of the pivots abd bearing don't require any lube, just keep them clean.
Digital scales crash. Beam scales will last forever if they are taken care of. Certainly they can be bent, broken, dirty/dusty, dinged, etc, and otherwise physically damaged but they don't "wear out" at all.
