Two things wear rollers out faster than normal use: temperature swings and the original roller material. This area sits in a cold-moderate climate band, which means the steel track contracts in winter and expands in summer every single year. On a door that's original to a 1983 build, that's four decades of expansion and contraction working against the roller stem, the thing most likely to snap or bend before the wheel itself fails outright.
Steel rollers also just don't hold up the way later nylon designs do. If your door still has the rollers it shipped with, they were never meant to run maintenance-free for forty years, and most houses in McLeansville are at or past that mark now. We don't find much call for anything exotic here - it's straightforward wear, consistent with the build year, not a sign of a bigger structural problem with the door.
