Urethane vs. Neoprene Belts

[JesseK]

Part #'s would definitely help. For example, the little 1/4" round urethane belts offered by McMaster will either have too much slip or cause too much torque loss as the belts round the pullies due to tightening to remove the slip.

I read a post regarding types of belts in drives, and I was considering using 3/8" 0.2 pitch for both steering and driving the modules.

Hmm, for part numbers... how about comparing 1679K19 (urethane) and 6484K219 (neoprene)? They're both 3/8" 0.2 pitch, single sided with trapezoidal teeth, and have an outer circle of 9".
