V-Belt Pulley Components


The shaft is a critical component that supports the pulley and transmits rotational motion. It must be precisely machined to ensure proper alignment and operation.


The hub connects the pulley to the shaft and provides structural support. It is usually made from durable materials to withstand high levels of stress and torque.


The groove is designed to accommodate the V-belt and ensure efficient power transmission. Proper groove dimensions are essential for optimal belt engagement and operation.


The bore is the central hole in the pulley through which the shaft passes. It must be accurately sized to provide a secure fit and prevent slippage.


The keyway is a slot that aligns with a key on the shaft, providing additional security and preventing rotational slippage. It is crucial for applications requiring precise timing and alignment.

How to Choose or Customize the Right Belt Pulley

Load Capacity

Understanding the load capacity is vital for selecting the right belt pulley. It ensures that the pulley can handle the operational forces without failure.

Operating Environment

Consider the operating environment, including temperature, humidity, and exposure to chemicals. These factors influence the material choice and design of the pulley.

Speed Requirements

The speed at which the pulley will operate affects its design and material. High-speed applications require pulleys that can withstand centrifugal forces and maintain stability.

Alignment Precision

Precise alignment is crucial for efficient power transmission and reduced wear. Selecting a pulley with appropriate alignment features ensures smooth operation.

Material Selection

Choosing the right material is essential for durability and performance. Materials like steel, aluminum, and composites offer different benefits depending on the application.
