Round Belts & Pulleys

What are Round Belts?

Round belts, also known as O-ring belts, are looped belts with a circular cross-section. They are commonly used in low torque applications.

Advantages of Round Belts

They offer excellent flexibility and are easy to install. Additionally, their uniform cross-section ensures smooth and consistent power transmission.

Applications of Round Belts

Round belts are typically used in light-duty applications, such as in small machinery, conveyors, and food processing equipment.

Compatibility with Different Pulleys

These belts are compatible with grooved pulleys specifically designed to accommodate their circular profile, enhancing grip and efficiency.

Material Choices for Round Belts

Round belts are made from various materials, including rubber, polyurethane, and silicone, each offering distinct advantages in terms of flexibility and durability.

Types of V-Belt Pulleys

Classical V-Belt Pulleys

These pulleys are designed to accommodate traditional V-belts with a trapezoidal cross-section, offering reliable performance in a wide range of applications.

Narrow V-Belt Pulleys

Engineered for high-power transmission, narrow V-belt pulleys are suitable for compact installations where space is constrained.

Double-Sided V-Belt Pulleys

These pulleys allow for power transmission on both sides of the belt, ideal for complex machinery requiring multi-directional drive capabilities.

Variable Speed V-Belt Pulleys

Designed to adjust the driven speed ratio, these pulleys are essential for applications where variable speed control is necessary.

Light-Duty and Heavy-Duty V-Belt Pulleys

Depending on the application requirements, light-duty pulleys are used for lower power transmissions, while heavy-duty pulleys are built for high-torque applications.

V-Belt Pulley Components


The sheave is the grooved wheel that holds the belt, facilitating motion transfer and ensuring alignment.


The bore is the central hole through which the pulley is mounted to the shaft. Precisely machined bores ensure a secure fit.


A keyway is a slot that runs along the bore, allowing the pulley to be locked onto a shaft using a key, preventing slippage.


Flanges are the raised edges on the sides of the sheave that keep the belt aligned and prevent it from slipping off during operation.

Set Screws and Bushings

Set screws and bushings secure the pulley to the shaft, ensuring a firm attachment and preventing any unintended movement.

How to Choose or Custom-Make the Right Belt Pulley

Determine the Pulley Size

Accurate measurements of the pulley diameter and width are crucial for ensuring compatibility with the belt and the machinery.

Consider the Material

Choose a material that offers the necessary durability and resistance to wear, based on the application¡¯s demands.

Analyze Operational Conditions

Consider factors such as load, speed, and environmental conditions to select a pulley that can withstand operational stress.

Check the Bore and Keyway Specifications

Ensure that the bore diameter and keyway dimensions match the shaft specifications to achieve a secure and reliable fit.

Evaluate the Belt Compatibility

Verify that the pulley is compatible with the type and size of the belt being used to ensure efficient power transmission.
