Your Trusted V Belt Supplier in China
ZQDrive v belt can stably transmit power from the motor to the pulley, providing power for water pumps, fans, compressors, and more. V belt strictly adheres to ISO and DIN standards, is manufactured using high-quality rubber and high-strength cord fabric. Whether you need to operate in high-temperature, high-humidity, or high-load environments, the ZQDrive v belt maintains excellent wear resistance and tensile strength.
When the drive system is overloaded, the V belt slips on the pulley, thereby protecting the drive components. At the same time, the V belt’s excellent elasticity effectively cushions load impacts during equipment operation, reducing mechanical vibration and noise while enhancing operational smoothness. Furthermore, to meet the diverse needs of various industries, ZQDrive offers a range of specifications and models of V belts to help your equipment operate efficiently.
Different Types of V Belt
Learn About Your V Belt Functions
ZQDrive v belts feature oil-resistant and heat-resistant properties, enabling your equipment to operate stably within a temperature range of -40°C to 90°C. The unique V-shaped groove structure of the V belt not only provides greater friction and traction but also effectively prevents the belt from slipping or detaching from the drive during use. During operation, the V belt’s static electricity conduction properties further enhance the safety of your equipment. Its compact structural design allows for smaller pulley spacing, making assembly easier while reducing vibration and achieving efficient and smooth power transmission.
V Belts Provide Efficient Power for Your Equipment
ZQDrive v belts efficiently transmit power from the drive pulley to the driven pulley, enabling the transfer and distribution of mechanical energy. V belts are widely used in applications such as automobiles, agricultural equipment, trucks, industrial machinery, construction, and HVAC systems to meet your diverse needs.
In automobile engines, V belts are commonly used to drive components such as alternators, power steering pumps, and air conditioning compressors, ensuring the stable operation of your automobile engine.

- Measure V Belt Length
Use a cloth tape measure to measure the length. If a cloth tape measure is not available, use a thin string or nylon rope. Wrap it tightly around the outer circumference of the V-belt, mark the position after tightening, and then measure the length of the rope with a ruler. When measuring, keep the V belt slightly taut, and ensure that the cloth tape measure or string is tightly against the back of the V belt.
- Measure V Belt Width and Height
Use a caliper or ruler to measure the width and height at the top of the V belt to determine the cross-section type of the V belt.
V-belt numbers can help you quickly identify your V-belt model and size. Common V-belt numbers consist of letters and length. The letter part indicates the cross-section model of the V belt, while the other numbers indicate the length.
What if there are no V-belt numbers or the numbers are worn out? First, use a caliper to measure the top width and height of the V belt to determine the cross-section type. Then, use a cloth tape measure or string to measure the length of the V belt. Based on the measured width, height, and length, refer to the relevant model reference table to determine the specific V-belt model.
The following methods can be used to determine whether the V belt is damaged:
- Cracks, tears, or wear: Visible cracks, breaks, or abnormal wear on the surface of the V belt indicate that the belt has aged or is damaged and needs to be replaced.
- Hardening or deformation: If the V belt becomes stiff or deformed, it indicates that the rubber material has degraded.
- Abnormal noise: Screeching or squeaking sounds during operation typically indicate v-belt slippage, loosening, misaligned pulley grooves, or insufficient belt tension.
- High temperature or overheating: Abnormal heating of the V belt surface or related bearings indicates V belt slippage, excessive tension, or system malfunction.
Refer to the vehicle manual and regularly check the condition of the V belt. Generally, replace the V belt every 60,000 to 100,000 km, or every 4 to 6 years, to avoid engine component failure due to belt breakage, which could affect vehicle safety and performance.
The components of a V-belt include:
- Cover Fabric: Used to protect the internal structure of the V belt, enhancing wear resistance and ageing resistance.
- Adhesion Rubber: Mainly serves a cushioning and protective function, improving the flexibility of the V belt.
- Tensile Member: The main load-bearing part of the V belt, determining its strength and service life.
- Compression Rubber: Serves to support and stabilise the cross-section of the V belt, improving the structural stability of the V belt.
A V belt is usually made of a combination of materials. The main materials used in V belts include:
- Cover Fabric: Polyester
- Top Rubber: NR / EPDM / CR
- Tensile Member: Polyester
- Compression Rubber: NR / EPDM / CR
