Hi all, been looking for thrust or full complement roller bearings for my wind vane direction arrow for two days now, but have only found plain steel as an option for the most part. I found one company that will make one out of stainless (for $1100 ouch) and another that I'm waiting to hear back from(kaydon), but not much luck other wise. I've checked mcmaster, msc, and google. It has to fit around a 2" OD tube and will be exposed to the elements. Should I be worried about rusting? If i build a shell around it will that protect if from rusting? Can I or should I take one apart and have it painted? I've found bearings in ceramic, bronze, brass, or stainless but none of them are big enough. Ideally a stainless steel needle thrust bearing is what I want. Any suggestions.
