The tension of round rubber belts and its hardness has an important relationship. If you need the tension of round rubber belts is stronger, then their necessary the hardness is higher. Raw materials will also influence the tension of round rubber belts. Different hardness, the degree of stretching is also different. The user to choose the hardness of rubber belts, according to use the driving speed, the tension, the burden and other conditions. The hardness of round rubber belt: 50, 60, 70, 80, 90, 95.
Polyurethane round rubber belts have higher physical and chemical stability, so they need made from special molding process. Their strength length and tensile resistance are very good, so they have a good dimensional stability. Precision round rubber belts having very small tolerances, to ensure their thickness and length are accurate.
We are factory specializing in the production round rubber belts. Our products passed the ISO9001 quality system certification. We have advanced production machinery and equipment, testing instruments, and Independent laboratory. So, these are to ensure that we use high-quality raw materials to produce high-quality quality products.
