That variation would account for some premature failures, not a few motors randomly lasting 100 years by exceptional luck and skill. 100 years is just the performance you get when the thing is assembled correctly.

The classical bathtub curve of failures will skew the bulk of the failures out past a decade or so, but on the order of a century only the lucky few exceptionally-built, or exceptionally-maintained devices will last.
