Types of V-Belt Pulleys

Classical V-Belt Pulleys

Classical V-belt pulleys are designed for general-purpose power transmission. They are characterized by their trapezoidal cross-section and are compatible with standard V-belts.

Narrow V-Belt Pulleys

Narrow V-belt pulleys have a smaller cross-sectional width than classical V-belts. This design allows for higher power transmission efficiency and is suitable for high-speed applications.

Fractional Horsepower (FHP) V-Belt Pulleys

FHP V-belt pulleys are designed for low-power applications. They are commonly used in small machinery, appliances, and HVAC systems, providing reliable performance and easy maintenance.

V-Belt Pulley Components


The sheave, or pulley wheel, is the main component that interfaces with the V-belt. It is designed to guide and grip the belt effectively, ensuring smooth power transmission.


The keyway is a slot in the sheave that allows for secure attachment to the shaft using a key. This prevents slippage and ensures accurate alignment of the pulley on the shaft.


The bore is the central hole in the sheave that fits onto the shaft. Proper bore sizing is essential for secure mounting and efficient power transmission.


Flanges are optional components that provide additional belt guidance and support. They are particularly useful in preventing the belt from slipping off the sheave during operation.

Set Screws

Set screws are used to secure the sheave to the shaft. They provide additional holding power and prevent the sheave from moving along the shaft during operation.

Choosing the Right Belt Pulley

Load Requirements

Understanding the load requirements is crucial when selecting a belt pulley. Consider factors such as the amount of torque, speed, and power that the pulley needs to handle.

Operational Environment

The operational environment can significantly impact the performance and longevity of a belt pulley. Consider factors such as temperature, humidity, and exposure to chemicals or abrasive materials.


Ensure that the selected pulley is compatible with the existing belt and system components. Mismatched components can lead to inefficiencies and premature wear.

Material Selection

The material of the pulley should be chosen based on the application's specific requirements. Consider factors such as strength, weight, and resistance to wear and corrosion.

Customization Options

Customization options, such as specific groove profiles and sizes, can optimize the performance of the pulley. Work with manufacturers to tailor the pulley to your exact needs.
