Anyone know whether a 35 or 36mm ID bearing can be purchased off the shelf

I'm guessing it has to be a roller bearing or needle bearing if it exists,
but I honestly don't know where to start for such a large one as all my
bearing usage is smaller than that...

I'd love one with an inner and outer race rather than a needle bearing
because the needle bearings take out the shaft they run on when they
disintegrate... But I'll settle for any answer that can be found right now.
They are called "thin section" bearings, and a
number of makers have separate
catalogs of these. They are made just like
standard ball bearings but with thinner
races and smaller balls than you would see in
general use. Thus the ratio of
inner to outer radius can be a lot closer. I
think any bearing distributor should
have these catalogs.
