V-Belt Pulley Components


The hub is the central part of the V-belt pulley that connects to the shaft. It is designed to provide a secure and stable connection, ensuring efficient power transmission.


The grooves in a V-belt pulley are designed to match the profile of the V-belts. Proper groove design ensures optimal belt alignment and reduces the risk of slippage.


Flanges are optional components that provide additional support and guidance for the belts, preventing them from slipping off the pulley during operation.

Balance Weights

Balance weights are used to ensure the pulley remains balanced during rotation. Proper balancing reduces vibrations and wear, extending the life of the pulley and associated belts.


V-belt pulleys are made from materials such as cast iron, steel, or aluminum. The choice of material affects the pulley¡¯s durability, weight, and compatibility with different environments.

How to Choose or Customize a Suitable Belt Pulley

Determine the Application Requirements

Understanding the specific application requirements is the first step in choosing or customizing a belt pulley. Consider factors such as load capacity, speed, and environmental conditions.

Material Selection

Choose a material that meets the demands of the application. For example, cast iron is suitable for heavy-duty applications, while aluminum is ideal for lightweight and corrosion-resistant needs.

Design Specifications

Customize the groove dimensions, pitch, and pulley diameter to match the belt specifications. Proper design specifications ensure efficient power transmission and reduce the risk of slippage.

Consider Environmental Factors

Take into account the operating environment, such as temperature, humidity, and exposure to chemicals. Select materials and coatings that can withstand these conditions to ensure longevity and performance.

Evaluate Load and Speed Requirements
