Where to buy round rubber belting online? So far, I have one or
two possibilities, McMaster-Carr and Cadence Supply Company.

Also. How can you tell the minimum pulley outer diameter of a
rubber belt? McMaster-Carr says that their 3/16 inch rubber belts
have a minimum pulley diameter of 1 1/2 inches. Is there some
rule, like a belt that is twice as thick requires a pulley that is
twice as wide?

Any other information about rubber belting is appreciated. Like
resources for gluing the ends together. I will check YouTube.

Thanks.

Questions lead to more questions! What are you using it for? The
only thing I've used round rubber belts for were turntables and sewing
machines. Have used a bunch of square belts for small-power stuff
like microwave oven stirrers and the like. At one time there was a
replacement plastic belting material that was round, the ends were
welded together with a small flame, I believe it was urethane. Only
have seen it in catalogs. And round leather belting had a vogue in
the distant past for running dental drills, I have one. If you want
it to replace existing belts, there's probably a substitute. There
are better power-transfer options these days for new designs.

You might see if there's something in a really old Machinery's
Handbook for what you're looking for.
