low friction pulley

low friction pulley

(OP)
I am designing a force calibration rig for an electric propulsion thrust stand.  The design requires a pulley to support the loading of calibration weights.  The pulley needs: to have minimal friction, support about 100 grams, physically 1-2 inches in diameter, and have an edge groove that will constrain a thread-sized string.

Does anyone know of a supplier for such a pulley (price is not important)?  What type of thin strings are available?  Spider wire?

with nylon monofilament thread.

Only snag is, I don't think those pulleys are ball bearing - although they are designed to be low friction for lab experiments. You would have to check.
