Types of V-Belt Pulleys

Classical V-Belt Pulleys

Classical V-belt pulleys are designed for a wide range of industrial applications. They feature a simple design that enables effective power transmission and long-lasting performance.

Narrow V-Belt Pulleys

Narrow V-belt pulleys are used in applications where space is limited. Their compact design allows for efficient power transmission in tight spaces without compromising performance.

Double V-Belt Pulleys

Double V-belt pulleys, also known as hexagonal pulleys, are used in applications requiring bi-directional power transmission. Their unique design allows belts to wrap around both sides of the pulley.

Variable Speed V-Belt Pulleys

Variable speed V-belt pulleys offer adjustable drive ratios, making them ideal for systems requiring variable speed control. This flexibility enhances the efficiency and versatility of the machinery.

Light Duty V-Belt Pulleys

Light duty V-belt pulleys are designed for less demanding applications. They are typically used in household appliances and smaller machinery where high power transmission is not required.

V-Belt Pulley Components


The hub is the central part of the pulley that attaches to the shaft. It ensures that the pulley is securely fixed and can transfer torque efficiently.


The rim is the outer part of the pulley where the belt runs. Its design ensures proper seating of the belt, facilitating efficient power transmission.


Some V-belt pulleys are equipped with flanges on either side to prevent the belt from slipping off during operation. Flanges are particularly useful in high-speed applications.


The grooves in V-belt pulleys are precisely machined to match the profile of the V-belt. Properly designed grooves ensure maximum contact and grip between the belt and the pulley.


The keyway is a slot in the hub that accommodates a key, ensuring a secure and aligned connection between the pulley and the shaft. This prevents slippage and maintains the integrity of the power transmission system.

How to Choose or Customize the Right Belt Pulley

Load Requirements

Consider the load requirements of your application. Ensure that the pulley can handle the maximum load without compromising performance or safety.

Environmental Conditions

Analyze the environmental conditions where the pulley will be used. Factors such as temperature, humidity, and exposure to chemicals can affect the material and design of the pulley.


Ensure compatibility with existing systems. The pulley should match the specifications of the belts and shafts used in your machinery to ensure seamless integration.

Material Selection

Select the appropriate material based on the application's requirements. Materials like aluminum, steel, and plastic offer different benefits in terms of weight, durability, and resistance to wear.

Customization Options

Consider customization options to meet specific needs. Custom bore sizes, surface treatments, and additional features can enhance the pulley¡¯s performance and longevity.
