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 provide excellent grip and are suitable for a wide range of applications, ensuring reliable power transmission.

Narrow V-Belt Pulleys

Narrow V-belt pulleys are designed for high-performance applications. Their narrower profile allows for higher power transmission and efficiency, making them ideal for demanding environments.

Double V-Belt Pulleys

Double V-belt pulleys feature grooves on both sides, enabling the use of two belts simultaneously. This configuration enhances power transmission capacity and provides redundancy, improving system reliability.

Variable Speed V-Belt Pulleys

Variable speed V-belt pulleys allow for adjustable speed control within a system. By altering the pulley diameter, operators can fine-tune the speed and performance of the machinery to meet specific requirements.

Micro V-Belt Pulleys

Micro V-belt pulleys are used in compact and high-precision applications. Their small size and tight tolerances make them suitable for intricate mechanical systems requiring precise power transmission.

V-Belt Pulley Components


Sheaves are the grooved wheels within a V-belt pulley system. They guide and support the belt, ensuring it remains correctly positioned during operation. Properly designed sheaves minimize wear and tear on the belt.

Bearing Assemblies

Bearing assemblies within V-belt pulleys reduce friction and support the rotational motion of the pulley. High-quality bearings ensure smooth and efficient operation, extending the lifespan of the entire system.


Flanges are the raised edges on either side of the pulley groove. They prevent the belt from slipping off the pulley, maintaining proper alignment and ensuring continuous power transmission.

Keys and Keyways

Keys and keyways are components that lock the pulley onto the shaft, ensuring a secure and stable connection. This prevents slippage and misalignment, which could otherwise lead to system failure.


Fasteners, such as bolts and screws, are used to assemble and secure various components of the V-belt pulley system. High-quality fasteners ensure the integrity and stability of the entire setup.

Choosing or Customizing the Right Belt Pulley

Load Capacity

Determining the load capacity is crucial when selecting a belt pulley. It must be capable of handling the maximum load without compromising performance or safety.

Material Selection

Choosing the right material for the belt pulley is essential. Factors such as durability, weight, and environmental resistance should be considered to ensure optimal performance.

Dimensional Specifications

Accurate dimensional specifications, including diameter, width, and groove size, are necessary to ensure proper fit and function within the mechanical system.

Speed Requirements

Understanding the speed requirements of the application helps in selecting a pulley that can operate efficiently at the desired RPM, ensuring consistent performance.

Environmental Conditions

Considering the environmental conditions, such as temperature, humidity, and exposure to chemicals, is vital in selecting a pulley that can withstand the operational environment.
