Round Belts & Pulleys

Versatility in Design

Round belts and pulleys offer flexibility in design, accommodating various industrial applications. Their cylindrical shape allows them to easily transfer power in different directions and angles, making them ideal for complex machinery setups.

Material Selection

These belts and pulleys are available in materials such as polyurethane, rubber, and silicone. Each material provides specific benefits, including resistance to wear, chemical stability, and flexibility, depending on the operational environment.

Smooth Operation

The rounded profile of these belts results in a smoother operation, reducing vibration and noise. This makes them suitable for applications where quiet and efficient power transmission is essential.

Easy Maintenance

Round belts are often easier to install and replace compared to other belt types. Their design allows for quick adjustments and maintenance, minimizing downtime in industrial operations.


Round belts and pulleys are commonly used in light-duty power transmission applications such as in packaging machinery, textile equipment, and office machines. Their adaptability and efficiency make them a preferred choice in these scenarios.

Types of V-Belt Pulleys

Classical V-Belt Pulleys

Classical V-belt pulleys are characterized by their trapezoidal cross-section, which provides a high level of grip and power transmission efficiency. They are suitable for a wide range of industrial applications due to their robust design.

Narrow V-Belt Pulleys

Narrow V-belt pulleys are designed to offer higher power transmission in a compact form factor. Their smaller cross-sectional area allows them to fit into tight spaces while maintaining high operational efficiency.

Double V-Belt Pulleys

Double V-belt pulleys, also known as hexagonal pulleys, have grooves on both sides. This design enables them to drive multiple belts simultaneously, providing greater flexibility and power distribution in complex machinery.

Variable Speed Pulleys

Variable speed pulleys allow for adjustable speed ratios, making them ideal for applications that require variable speeds. Their design accommodates changes in belt position, providing precise control over operational speeds.

Flat V-Belt Pulleys

Flat V-belt pulleys are used in applications where high-speed power transmission is required. Their flat surface allows for smooth operation and is often employed in conveyor systems and high-speed machinery.

V-Belt Pulley Components


The shaft is the central component on which the pulley rotates. It must be robust and precisely machined to ensure smooth and efficient power transmission.


The groove of the pulley determines the fit and grip of the belt. Its dimensions must match the belt profile to prevent slippage and ensure optimal power transmission.


The flange provides additional support to the belt, preventing it from slipping off the pulley. It ensures the belt remains aligned during operation, enhancing reliability.


The hub is the central part of the pulley that connects to the shaft. It must be precisely engineered to ensure a secure fit and efficient power transfer.


The keyway is a slot that ensures the pulley is securely fixed to the shaft, preventing it from rotating independently. This component is crucial for maintaining alignment and power transmission efficiency.

Choosing the Right Belt Pulley

Load Requirements

Understanding the load requirements of the application is critical. The pulley must be designed to withstand the operational loads without deforming or failing.

Environmental Conditions

Environmental factors such as temperature, humidity, and exposure to chemicals must be considered. The material and design of the pulley should be capable of withstanding these conditions.

Speed Specifications

The operational speed of the machinery will influence the design of the pulley. High-speed applications require pulleys that can handle increased rotational speeds without excessive wear.


Ensuring compatibility with existing systems is essential. The pulley must fit seamlessly into the current setup, including alignment with other components and belts.

Material Selection

Selecting the appropriate material based on the application¡¯s demands will enhance performance and longevity. Consider factors such as strength, weight, and resistance to wear.
