Nitta’s PolyBelt™ series is the choice of many of the world’s largest yarn equipment manufacturers. The strong nylon cores that the belts are made of do not allow any stretch, so the quality of the yarn is not compromised. High friction, yet abrasive resistant rubber covers, allow for a longer belt life combined with fast and consistent spindle speed. Nitta is proud that our belt outlasts the competition’s belt on today’s highest speed OE machinery.
