The belt is a GT2 5mm pitch x 15mm wide gates timing belt. We used it because it was the smallest available size to allow for a moderate Factor of Safety for one arm to lift the entire robot.
The rollers are simply sleeve bushings (SAE 841 oil impregnated bronze) on an aluminum shaft. We wanted to use delrin rollers on the shafts, but had no desire to machine them ourselves. The bronze rollers were not ideal, but they worked fine.
Hope this helps.
