Rubber O Rings?

[benbenbob1]

Does anyone know what those Rubber O'Ring drive belts are called? They are used mostly for belt sander type conveyor systems. Also, does anyone know a site where these belts can be found? They come in different colors.

We found some O ring material at a local rubber dealer.
