One-Stop Narrow V Belt Supplier in China
Narrow V-belt (also known as wedge v belt) is a transmission belt designed specifically for effectively transmitting large torque in compact installation spaces. It complies with RMA and ISO standards and has antistatic, oil-resistant, and heat-resistant properties, enabling stable operation even under various harsh conditions.
The wedge-shaped cross-section of the narrow V-belt ensures adequate engagement between the belt and the pulley groove, thereby reducing slippage and improving transmission efficiency. Its unique structural design enables it to transmit greater loads even in equipment with limited space.
Compared with traditional V-belts, ZQDrive narrow V belts can help you achieve a more space-saving layout while providing high-speed drive and reducing operating and maintenance costs. Therefore, they are widely used in a variety of mechanical transmission systems.

Save Space in Your Drive System with Narrow V Belt
A narrow V-belt is a transmission belt that is narrower than a traditional V-belt and is designed for applications with limited installation space or small pulley diameters. Its main advantage is that it saves space and provides excellent grip, high torque, high power transmission capacity, and high load-bearing capacity in compact spaces.
Compared to a traditional V-belt, ZQDrive’s narrow V-belt can transmit up to three times the horsepower in the same drive space and can handle drive requirements ranging from 1 to 1,000 horsepower. In addition, it can transmit the same load while occupying only 1/2 to 2/3 of the space of a traditional V-belt. For this reason, narrow V belts are ideal for industrial applications with space, power, and load requirements, helping you achieve smaller, more compact, and efficient drive systems.
Wedge Design Helps You Achieve Efficient Transmission
Narrow v belt features a narrower, deeper wedge-shaped cross-section design, enabling easy installation into smaller pulley grooves. This design not only effectively reduces slippage but also withstands higher loads, thereby enhancing transmission efficiency. ZQDrive narrow V-belt is made from durable rubber and reinforced with tension cord, offering anti-static, heat-resistant, oil-resistant, and tear-resistant properties. It ensures a long service life even under harsh conditions. With the advantages of its narrow design, the narrow V-belt can help you reduce maintenance frequency, lower operating costs, and minimize downtime, providing an economical and efficient solution for your power transmission needs.
Narrow V Belt Efficient Transmission in Multiple Scenarios
ZQDrive narrow V-belt can transmit high power and is often used in industrial applications that bear heavy loads, but it also performs well in applications with lighter loads. Typical application areas include:
- Industrial machinery: Used in various industrial applications, including compressors, milling machines, crushers, conveyors, fans, pumps, and blending systems.
- Agricultural equipment: Used in tractors, seeders, lawn mowers, scarifiers, combine harvesters, and other agricultural machinery.
- Mining and quarrying: Used in various heavy-duty equipment for mining and quarrying operations.
- Automotive and heavy-duty vehicles: Used in engine-driven accessory systems, such as power steering pumps and alternators.
The main difference between narrow v belt and classic v belt is:
- Shape: classic v belt has a trapezoidal cross-section, while narrow v belt has a narrower and deeper cross-section.
- Power transmission: Compared with classic v belt, narrow v belt has a transmission efficiency of over 95% and a power transmission capacity increase of 50% – 100%.
- Space utilization: Classic v belt has relatively high space requirements. Compared to classic v belt, narrow v belt allows for the use of smaller diameter pulleys, enabling a more compact drive design that is suitable for industrial applications with limited space or high load requirements.
In summary, narrow v belt is an optimized version of classic v belt with improved cross-section and tension cord structure, offering higher power transmission capacity, greater efficiency, and smaller space requirements. It is particularly suitable for high-power or compact drive applications.
The marking on a narrow v belt are usually indicated by a prefix and numbers. The prefix indicates the top width and type of the belt (such as 3V, 5V, 8V), while the number at the beginning represents the top width of the belt, with the unit being 1/8 inch. The numbers after the letter indicate the outside circumference of the belt.
For example, 3v325 belt refers to a narrow V-belt with a top width of 3/8 inch and an outside circumference of 32.5 inches.
The operating temperature range of narrow v belt is typically between -30°C and 80°C. If special high-temperature-resistant materials are used, the temperature range can be appropriately increased.
Narrow v belt mainly consists of the following components: cover fabric, tension cord, adhesion rubber, and compression rubber.
The cover fabric features abrasion resistance, oil resistance, heat resistance, and ozone resistance, effectively withstanding environmental erosion and reducing wear. The tension cord boasts high tensile strength, low elongation, fatigue resistance, and bending resistance, serving as the core component for transmitting tensile force and effectively resisting impact loads. The adhesion rubber securely bonds the tension cord to the compression rubber, functioning as both an adhesive and a cushion. Compression rubber is made from highly flexible composite rubber material, which exhibits minimal deformation under high loads.
The maximum belt speed of narrow v belt is generally 40 m/s. This speed limit is set to ensure the normal operation and service life of the narrow v belt, and to prevent problems such as vibration, noise, and excessive wear caused by excessive speed.
