Screen door roller

Hi - I have four sliding doors that are in need of having their rollers replaced due to corrosion and the wheels are totally locked regardless of the amount of 3-1 oil I put on them. It looks like the 84-074 is what I'm looking for (see attached photo of the screen's roller). Question, it has a steel roller and the screens sit on ocean front. Would I be better using the nylon rollers for these screens or should I replace what was used by the original manufacture some 25 years ago.
