This GT2 open timing belt is built for makers, engineers, and automation builders who need repeatable, low-backlash linear motion without constant re-tensioning.\u003c\/p\u003e\n\u003cp\u003eEach order is fulfilled as a continuous open-end roll cut to your selected length — available in 9mm (≈3\/8\") and 10mm (≈13\/32\") widths, with lengths from 1 meter (≈3.3 ft) up to 100 meters (≈328 ft). The belt body is molded from polyurethane (PU) with embedded steel wire cords for tensile reinforcement, giving it a stiffer, stretch-resistant core compared to standard neoprene GT2 belts.
