Round Belts & Pulleys

Material Types

Round belts are typically made from materials such as polyurethane and rubber. These materials provide flexibility, durability, and reliable performance in various industrial applications. Polyurethane belts offer excellent resistance to abrasion and chemicals, while rubber belts provide better elasticity and shock absorption.


Round belts and pulleys are commonly used in light-duty power transmission applications, such as in small machinery, conveyor systems, and office equipment. Their versatility and ease of installation make them ideal for a broad range of uses.


Round belts offer several benefits, including silent operation, ease of maintenance, and the ability to handle misaligned shafts. Their simple design allows for quick installation and replacement, reducing downtime in industrial environments.

Design Considerations

When selecting round belts and pulleys, design considerations must include belt tension, pulley diameter, and the type of load being transmitted. Proper alignment and tension are crucial for the efficient operation and longevity of the belt system.

Types of V-Belt Pulleys

Single-Groove V-Belt Pulleys

Single-groove V-belt pulleys are designed for applications where a single belt is used to transmit power. These pulleys are ideal for simple, low-power applications and are easy to install and maintain.

Multi-Groove V-Belt Pulleys

Multi-groove V-belt pulleys can accommodate multiple belts, allowing for higher power transmission and better load distribution. They are commonly used in industrial machinery and automotive systems where higher torque is required.

Variable Pitch V-Belt Pulleys

Variable pitch V-belt pulleys enable the adjustment of the pulley diameter, allowing for variable speed control in machinery. This flexibility makes them suitable for applications requiring precise speed adjustments, such as in ventilation systems and machine tools.

Double-Groove V-Belt Pulleys

Double-groove V-belt pulleys are used in systems where two belts are needed to increase power transmission capacity. They provide better balance and reduced vibration, making them suitable for high-performance applications.

Idler V-Belt Pulleys

Idler V-belt pulleys are used to guide the belt and maintain proper tension in the system. They do not transmit power but play a critical role in ensuring the smooth operation and longevity of the belt drive system.

V-Belt Pulley Components


The hub is the central part of the pulley that connects to the shaft. It provides stability and support to the pulley, ensuring it can withstand the forces generated during operation.


Flanges are the sides of the pulley that keep the belt in place. They prevent the belt from slipping off during operation, ensuring consistent power transmission.


The grooves in a V-belt pulley are designed to match the cross-sectional shape of the V-belt. These grooves ensure a secure fit, minimizing slippage and maximizing power transfer efficiency.


The keyway is a slot in the hub that accommodates a key, which locks the pulley to the shaft. This ensures that the pulley rotates with the shaft, providing reliable power transmission.


The bore is the central hole in the hub through which the shaft passes. The bore size must match the shaft diameter to ensure a secure fit and proper alignment of the pulley.

Choosing or Customizing the Right Belt Pulley

Load Requirements

Understanding the load requirements of your application is essential. Consider the amount of torque and power that needs to be transmitted. This will help in selecting a pulley that can handle the load without excessive wear or failure.

Speed Requirements

Determine the desired speed of the driven component. The pulley size and the ratio between the driver and driven pulleys will affect the speed of the system. Ensure the selected pulley can achieve the required rotational speed without compromising performance.

Environmental Conditions

Take into account the environmental conditions in which the pulley will operate. Factors such as temperature, humidity, and exposure to chemicals can affect the material choice and design of the pulley. Select materials that can withstand these conditions to ensure longevity and reliability.

Belt Type Compatibility

Ensure that the chosen pulley is compatible with the type of belt being used. The pulley grooves must match the belt profile to prevent slippage and ensure efficient power transmission. Verify compatibility with V-belts, timing belts, or other belt types as required.

Installation and Maintenance

Consider the ease of installation and maintenance when selecting a pulley. Opt for designs that allow for quick installation and easy access for maintenance tasks. This will minimize downtime and ensure smooth operation of the system.
