- Antistatic: Prevents static buildup, ensuring safe operation in sensitive industrial and electronic environments.
Round Belt Series
Round belt transmits power through friction between two or more pulleys. It relies on its elasticity and friction to transfer torque between pulleys. Compared with other belts, the biggest feature of the round belt is that its cross-section is circular or semi-circular, so its tension distribution is uniform, can better adapt to the installation of different angles, and provide smooth power transmission.
As a superior round belt manufacturers in China, we mainly produce polyurethane round belt, O-ring round belt and urethane round belt with reinforced core.
Round belt can be made from polyurethane, rubber or urethane with reinforced cord.
Round belt is highly flexible, for it is designed to run directionally adjustable and the ability to flex in any direction.
Round belt can withstand high tensile and tearing forces.
Round belt can be welded to ring shape by heating.

More Information
Round Belt vs V Belt
Round belts and V belts are two of the most common belt types used in power transmission systems. Round belts are ideal for light-duty applications, offering smooth operation, flexibility, and easy installation. V belts, on the other hand, provide higher durability, better power transmission efficiency, and are suitable for heavy-duty machinery. Choosing the right belt depends on the load requirements, pulley type, and operating conditions.
| Feature | Round Belt | V Belt |
|---|---|---|
| Shape | Circular cross-section | Trapezoidal cross-section |
| Power Transmission | Light-duty, moderate load | Heavy-duty, high load |
| Durability | Moderate | High |
| Flexibility | High | Moderate |
| Applications | Small machinery, conveyors | Industrial machines, engines |
| Installation | Easy | Moderate |
| Efficiency | Moderate | High |
FAQ
1.What are advantages of PU round belt compared with rubber round belt?
- Oil Resistance: Polyurethane has good oil resistance, it is suitable for oily environment.
- Aging Resistance: Polyurethane has better adaptability to the environment, especially strong resistance to ultraviolet light and ozone.
- Higher Tensile Strength: Compared with traditional rubber round belt, PU round drive belt has higher tensile strength and can withstand greater loads.
2.Does your company accept color customization for round belt?
Yes, we can customize color for round belt, when we get specific color of customer requirement, we will start customization color as Pantone, but usually it also has MOQ for order, like 500m or 1000m.
3.Is it possible to use round belts as transmission belts?
Yes, round belts can be used as transmission belts in many applications. They are ideal for light to medium load transmission, especially in small machinery, conveyors, and automated equipment. Round belts offer smooth power transfer, low noise, and flexibility, making them suitable for both linear and rotary motion. However, it’s important to choose the correct size, material, and tension for optimal performance.
4. What is the correct way to weld round belts?
Welding round belts should be done using a heat-fusion or hot-air welding method suitable for the belt material (e.g., PU/urethane). Steps generally include:
- Cut the belt ends cleanly and evenly.
- Align the ends accurately without twisting.
- Apply heat using a specialized welding tool or hot-air gun until the material softens.
- Press the ends together firmly and allow them to cool under pressure.
- Test the welded joint to ensure strength and flexibility.
