Types of V-Belt Pulleys

Classical V-Belt Pulleys

Classical V-belt pulleys are the most common type, characterized by their trapezoidal cross-section. They offer reliable performance in standard industrial applications.

Narrow V-Belt Pulleys

Narrow V-belt pulleys are designed for high-power applications where space is limited. Their narrower profile allows for more compact pulley systems without sacrificing performance.

Fractional Horsepower V-Belt Pulleys

These pulleys are used in low-power applications, such as household appliances and light machinery. They are designed to handle fractional horsepower loads efficiently.

Double V-Belt Pulleys

Double V-belt pulleys feature grooves on both sides, allowing them to engage multiple belts simultaneously. This design is ideal for applications requiring high torque transmission.

Variable Speed V-Belt Pulleys

Variable speed V-belt pulleys allow for adjustable speed control. They are used in applications where precise speed regulation is crucial, such as in machine tools and conveyors.

V-Belt Pulley Components


The hub is the central part of the pulley that attaches to the shaft. It plays a crucial role in ensuring the pulley remains securely fastened during operation.


Flanges are the raised edges on the outer circumference of the pulley. They prevent the belt from slipping off, ensuring continuous and accurate power transmission.


Grooves are the channels where the belt sits on the pulley. The design and size of the grooves are critical for proper belt engagement and efficient power transmission.


The keyway is a slot that accommodates a key, securing the pulley to the shaft. This feature prevents the pulley from rotating independently of the shaft.

Set Screws

Set screws are used to lock the pulley in place on the shaft. They provide additional security, ensuring the pulley remains aligned and functional during operation.

How to Select or Customize the Right Belt Pulley

Load Capacity

Determine the load capacity required for your application. This ensures the pulley can handle the operational demands without failure.

Speed Requirements

Consider the rotational speed of the pulley. Different applications require varying speeds, so selecting a pulley that matches your speed requirements is crucial.

Environmental Conditions

Assess the environmental conditions, such as temperature, humidity, and exposure to chemicals. These factors influence the material choice and design of the pulley.

Belt Compatibility

Ensure the pulley is compatible with the belt type and size you intend to use. Proper compatibility guarantees efficient power transmission and reduces wear and tear.

Customization Options

Explore customization options to meet specific application needs. Customizing the diameter, length, and material can enhance the pulley¡¯s performance and longevity.
