NN in conveyor belts stands for "Nylon-Nylon." It refers to the type of fabric used in the construction of the conveyor belt. Nylon-Nylon conveyor belts are made with both the warp and weft (lengthwise and crosswise threads) using nylon fibers. This type of construction provides several advantages: High Strength: Nylon-Nylon belts are known for their high tensile strength, making them suitable for heavy-duty applications. Durability: They offer excellent resistance to wear and tear, ensuring a long service life. Flexibility: These belts are highly flexible, which allows for better performance in systems with smaller pulley diameters. Moisture Resistance: Nylon fibers provide good resistance to moisture, making NN belts suitable for wet environments. NN conveyor belts are commonly used in industries such as mining, construction, and manufacturing due to their robustness and reliability.
