with the bearing??????????????????
please keep it friendly:hug1:....im just asking.

I've had my wire drive pound ball bearings (good ones) into dust. Make sure there's no angular preload
on the stub shaft.

Wow...several posts have gone away on this thread.

Bearings are better and using ceramic or SS is key. How could they not be? Maybe that is the real question.

What's better? No idea.
How could ball bearings not be better? Like one of the disappeared posts said, a thin film of water in a bushing could potentially prevent any metal-metal contact at all as ferofluid bearings do in hard drives, ferofluid bearings are essentially a bushing but with magnetised fluid to keep a thin layer around the shaft, I don't think any of us has the technology to see inside a strut under way but after experiencing both the temperature and noise levels of computer hard drives dropping by previously unheard of amounts when they went from ballraces to feroflud bearings I wouldn't totally discount plain bearings in water.
