Which load are you worried about damaging the bearing?

My understanding was this was a discussion about a vertical tower/turbine
where side thrusts will be very powerful and create a wear pattern.

There are wind maps (that I think someone posted a link to) that will give a
a category number such as 4 or 5 etc. I'm in a zone 3 and they call that
"marginal." I would call it something more like a waste of effort and
money. From everything I've read wind power is not really viable unless you
have frequent "blow your hat off" wind, at least a 35 foot tower, and no
obstacles for hundreds of feet.

I suggest you find out how much fees and permits would cost before you buy
anything. You might be able to get away with it for a while but sooner or
later somebody is probably going to call the extension cord police. In my
area the permits would cost me about $20,000 or more. I would probably have
to hire an engineer to evaluate the site and structure and also hire a
biologist to do an environmental impact study. They also have regulations
about how far it has to be from neighboring property (50 feet). So, if
someone was to call Code Enforcement and complain about any suspicious wind
generator in my area first they "open a case." This costs about $170. Then
the party whom the case was opened on is charged an hourly fee (something
like $160/hr) for all the time spent investigating the suspected violation.
I think there are other fees and charges too. They will not notify the
party (here anyway) of the amount owed--instead they attach a lean to the
owner's property. They will not notify the party that a lean has been
attached.

If you can get away with it that's great.

Didn't think about permit cost ? I wonder if it affect property tax or
something? I'm in category 2 , which seems to cover most of ohio.
