D-Type V-Belt
Product Introduction
The D-type V-belt is a heavy-duty industrial drive V-belt with a larger cross-section and greater load capacity, suitable for high power, heavy load, and large machinery drive systems. The product is made of high-quality rubber, high-strength polyester cords, and wear-resistant fabric, featuring excellent tensile strength, wear resistance, and stable transmission performance.
Compared to A, B, and C-type V-belts, the D-type V-belt is suitable for larger power and higher torque industrial equipment, making it an important transmission component commonly used in mining, metallurgy, and heavy machinery fields.

Product Structure
1. Top Rubber Layer
Made of wear-resistant, heat-resistant rubber materials to protect the internal structure from external damage.
2. Tensile Layer
Uses high-strength polyester rope or aramid rope to enhance the belt's load-bearing capacity and stability.
3. Cushioning Rubber Layer
Reduces operational impacts and vibrations, improving flexibility and fatigue resistance.
4. Bottom Rubber Layer
Enhances friction performance between the belt and the pulley, increasing transmission efficiency.
5. Cover Layer
Features anti-slip, wear-resistant, high-temperature resistant, and aging-resistant properties.
