It will still be the wrong OD for the usual collection of bearing choices.

Go to the store and look at a PVC pipe fitting which is designed to join
pipes end to end. Picture in your mind what it would be like if you cut
off just the socket part from each end, that would leave you with two
bottomless sockets, in other words two collars that would slide over the
pipe so you can put them anywhere you want. Glue them where you want
them with the bearing sandwiched between them, using PVC cement and the
instructions on the bottle. - GWE

That sounds really good. I can't get all the details from your post.
Can you please explain the steps in details or draw a simple diagram?
Thanks.

I want to play around with small wind turbine. I want to buy a 1 inch
ball bearing from RadioShack and use a 1 inch pvc pipe as the shaft. I
can slide the pipe into the bearing, but I can't figure out what I can
use to prevent it from sliding up and down. I want it to be as
frictionless as possible. I can just screw in a nut or something, but
that would have lots of friction and wear my bearing quickly.


If you can get a bearing that fits PVC pipe, the best way I can think
of to
positively locate the bearing on the pipe OD is to get a 1" pipe
joint (straight
piece you butt 2 PVC pipes into to join them lengthwise) and saw it
in half,
then trim out the inside step the pipe would butt up against so the
thing will
slide over the OD of the pipe, decide where you want your bearing and
use PVC
glue to put this closely-fitting PVC collar where you want it
permanently, then
put on your bearing, then glue the other collar on the other side. No
rust, no
muss, no fuss.
