Round Belts & Pulleys

Flexibility and Versatility

Round belts and pulleys are known for their flexibility and versatility. They can handle a variety of applications, from light-duty tasks to more demanding industrial uses. Their ability to bend and twist without significant loss of efficiency makes them suitable for complex drive systems.

Material Options

Round belts are available in various materials such as rubber, polyurethane, and silicone. Each material offers specific advantages, such as chemical resistance, tensile strength, and temperature tolerance, allowing for tailored solutions to meet diverse needs.

Ease of Installation

The simplicity of round belt installation is another key advantage. They can be easily cut to length and joined using various methods, such as welding or mechanical fasteners, making them convenient for both maintenance and customization.

Low Maintenance

Round belts and pulleys typically require minimal maintenance. Their robust design and material composition ensure longevity, reducing downtime and operational costs associated with frequent replacements or repairs.


Round belts and pulleys are used in a wide range of industries, including textile manufacturing, food processing, and printing. Their ability to handle high-speed operations and provide smooth, quiet performance makes them ideal for these applications.

Types of V-Belt Pulleys

Classical V-Belt Pulleys

Classical V-belt pulleys are the most traditional and widely used type. They feature a trapezoidal cross-section that fits into corresponding V-belt grooves, providing efficient power transmission with minimal slippage.

Narrow V-Belt Pulleys

Narrow V-belt pulleys have a smaller cross-sectional profile compared to classical V-belt pulleys. This design allows for higher power transmission efficiency and is particularly useful in high-speed applications.

Double V-Belt Pulleys

Double V-belt pulleys are designed to accommodate two V-belts, providing additional grip and power transmission capabilities. They are ideal for heavy-duty applications where higher torque is required.

Variable Speed V-Belt Pulleys

Variable speed V-belt pulleys allow for adjustable speed ratios by changing the effective diameter of the pulley. This feature makes them highly versatile and suitable for applications requiring variable speeds.

Light-Duty V-Belt Pulleys

Light-duty V-belt pulleys are designed for applications with lower power requirements. They are typically smaller and made from lightweight materials, making them cost-effective and easy to install.

V-Belt Pulley Components


The groove is the part of the pulley that interacts with the V-belt. Its shape is critical for ensuring optimal contact and grip, thereby enhancing power transmission efficiency.


The hub is the central part of the pulley that connects to the shaft. It must be robust and well-aligned to ensure the stability and proper functioning of the pulley system.


Flanges are optional components that can be added to the sides of the pulley to keep the belt in place. They are particularly useful in applications with high-speed operations where belt movement could be an issue.


The bore is the hole in the center of the pulley through which the shaft passes. It must be precisely machined to ensure a snug fit and prevent any wobbling during operation.


The keyway is a slot in the pulley bore that accommodates a key to lock the pulley onto the shaft. This ensures that the pulley rotates in sync with the shaft, preventing slippage.

Choosing or Customizing the Right Belt Pulley

Load Capacity

Load capacity is a critical parameter when selecting a belt pulley. It determines the amount of power the pulley can transmit without failure. Understanding your system's load requirements is essential for making the right choice.


The material of the pulley affects its durability and performance. Choose a material that suits the environmental conditions and operational requirements. For instance, steel is ideal for heavy-duty applications, while aluminum is suitable for lighter tasks.

Size and Dimensions

The size and dimensions of the pulley must match the specifications of your drive system. Incorrect dimensions can lead to inefficiencies and potential malfunctions. Ensure that the pulley fits well with the belts and other components.

Groove Design

The groove design is crucial for the belt's grip and alignment. Different applications may require specific groove profiles. For example, deeper grooves provide better grip for high-torque applications.

Customization Options

If off-the-shelf pulleys do not meet your requirements, consider customization. Many manufacturers offer custom pulleys tailored to your specific needs, whether in terms of material, size, or groove configuration.
