V-Belt Pulley Components


The sheave is the grooved wheel that interacts directly with the V-belt, providing the necessary friction and alignment for efficient power transmission.


Bushings are used to secure the pulley to the shaft, allowing for easy installation and removal, and ensuring a tight fit to prevent slippage.


Flanges are integral to maintaining the belt's alignment within the pulley grooves, preventing lateral movement and ensuring efficient operation.


The hub is the central part of the pulley that connects to the shaft, providing structural integrity and support for the sheave and other components.


The keyway is a slot that accommodates a key, used to lock the pulley to the shaft, ensuring synchronized movement and preventing slippage.

How to Choose or Customize the Right Belt Pulley

Determine Load Capacity

Assess the load requirements of your application to ensure the pulley can withstand the forces exerted without deformation or failure.

Material Selection

Choose a material that offers the necessary strength, durability, and resistance to environmental factors such as corrosion and temperature variations.

Size and Dimensions

Accurately measure the required pulley size, including diameter and width, to ensure compatibility with your belt and system specifications.

Tension Requirements

Understand the tension requirements of your belt to select a pulley that can maintain proper tension, reducing wear and slippage.

Environmental Conditions

Consider the operating environment, including exposure to chemicals, moisture, and extreme temperatures, to select a pulley that can withstand these conditions.
