Overview of Round Belts

Round belts are typically used in light-duty applications and are known for their flexibility and ability to run smoothly over pulleys. They are often made from materials such as urethane or rubber for added durability.

Advantages of Round Belts

Round belts provide excellent grip and can handle misalignments better than flat belts. They also have a minimal slippage rate, ensuring efficient power transmission.

Applications of Round Belts

Round belts are commonly found in small machinery, printers, and conveyors due to their lightweight and versatile nature. They are ideal for applications requiring high-speed operations with low torque.

Types of V-Belt Pulleys

Classical V-Belt Pulleys

Classical V-belt pulleys are designed for general-purpose applications. They are characterized by their trapezoidal cross-section and are suitable for a wide range of industrial uses.

Narrow V-Belt Pulleys

Narrow V-belt pulleys are designed to handle higher loads and speeds compared to classical V-belts. Their narrower profile allows them to operate more efficiently in high-torque applications.

Light-Duty V-Belt Pulleys

Light-duty V-belt pulleys are used in applications that require minimal torque. They are typically found in home appliances and small machinery.

Variable Speed V-Belt Pulleys

Variable speed V-belt pulleys allow for adjustments in the speed of the driven component. This makes them ideal for applications requiring variable speeds, such as in machine tools and HVAC systems.

V-Belt Pulley Components


Sheaves are the grooved wheels within V-belt pulleys that guide and support the belt. They are designed to reduce friction and wear, ensuring smooth operation.


Flanges are the raised edges on either side of the sheave that keep the belt in place. They prevent the belt from slipping off during operation, ensuring safety and efficiency.


Hubs are the central part of the pulley that connects to the shaft. They are designed to securely hold the pulley in place, providing a stable foundation for power transmission.

Keys and Keyways

Keys and keyways are used to lock the pulley onto the shaft, preventing rotational slippage. They are critical components that ensure the pulley and shaft move in unison.

How to Select or Customize the Right Belt Pulley

Load Capacity

Determine the load capacity requirements of your application. This involves understanding the amount of power that needs to be transmitted and selecting a pulley that can handle that load.

Belt Speed

Consider the operational speed of the belt. The pulley must be compatible with the belt speed to ensure efficient power transmission without causing excessive wear or slippage.

Material Requirements

Choose the appropriate material based on the environmental conditions and the application. For instance, corrosion-resistant materials like stainless steel may be required for outdoor or marine applications.

Pulley Diameter

Select the correct pulley diameter to match the belt and the operational requirements. The diameter affects the speed and torque transmission capabilities of the pulley system.

Alignment and Tension

Ensure proper alignment and tension of the belt and pulley system. Misalignment can lead to increased wear and reduced efficiency, while improper tension can cause slippage or damage to the belt.
