    Might look into a worm gear translation. That will drop the speed of the final drive while letting the motor run in it's efficient range. I still think nylon is your best bet. It is produced with petrolium. When it heats up it emits an oil based self lubricating film. I wouldn't rely on material recomendations ftom unqualified individuals.

    And i wouldn't rely on recommendations from people called todd :-)

    Is that enough tit for tat ?
    Or do you want to continue the childish name calling and snide comments ?

    Unless the part is used in water or very moist environments, I advise nylon. As an amorphous polymer, TPU with its lower hardness will display much more fatigue over time and fail due to stress cracking. Compare TPU to a very hard bunch of spaghetti, while nylon has a more integral molecular structure that brings about its strength.

    take a look at ninjatek's new armadillo filament.
    It's a super tough very rigid polyurethane based material, 90% more abrasion resistant than nylon and stiffer than abs with much better impact resistance.

    I've just ordered a 10 metre sample to try out.
