What Are Belt Pulleys?
Belt pulleys are mechanical components used to transfer motion and power between machine parts. They work by engaging with belts, which are looped around the pulleys to create rotational force. The type of pulley you choose depends on your system and the kind of belt used, whether it's a V belt, timing belt, or flat belt. Different pulleys are used to suit specific requirements such as load-bearing capacity, power transmission, and the need for precise positioning or synchronisation, which is why selecting the correct pulley is essential for the smooth operation of your machinery.
Types of Belt Pulleys
We offer a variety of belt pulleys, each designed to meet specific needs and applications:
V Belt Pulleys
V belt pulleys are commonly used in systems where frictional forces are essential for transmitting power between shafts. They are ideal for heavy-duty applications, offering efficient power transmission and minimal slippage. The pulley surface design of V belt pulleys ensures a secure fit and long-lasting performance.
Timing Pulleys
Timing pulleys are used with timing belts to ensure precise operation and avoid slippage. These pulleys are designed with teeth that mesh with the corresponding teeth of a timing belt, providing accurate and synchronised movement. Timing pulleys are ideal for applications where precision and reliability are critical, such as in robotics, conveyors, and machinery that requires exact positioning.
Flat Belt Pulleys
Flat belt pulleys are used in systems that require non-angled belt paths. These pulleys are often used in applications with lower speeds and power requirements. They are efficient for power transmission in flat belt systems and are commonly used in industrial applications.

How to Choose the Right Pulley for Your System
Choosing the right belt pulley depends on a few key factors:
Belt Type: Consider whether you need a V belt, timing belt, or flat belt. Each type of belt interacts differently with the pulley.
Load and Power: Determine the amount of power your system requires and whether you need a pulley that can handle higher torque or frictional forces.
Precision and Speed: If your system requires high precision (such as in a timing pulley system), choose a timing pulley that fits your belt’s teeth accurately.
Material: Pulleys made from steel are ideal for heavy-duty applications, while aluminium pulleys are suitable for lighter, more precise work.
Our team at Aire Bearings can guide you through the selection process to ensure you get the correct components for your system.
