Timing belts and pulleys are essential components utilized across various applications like 3D printing, CNC, and robotics. These specialized pulleys typically feature teeth or pockets around their outer diameter, which engage with corresponding features on the belt.

It’s important to note that these teeth and pockets are solely for timing purposes and not for power transmission. For instance, the GT2 pulley series and belts designed for linear motion often feature a rounded tooth profile to ensure smooth and accurate engagement within the pulley groove.

High-quality aluminum is commonly used to construct these pulleys, ensuring durability, practicality, and ease of use. This combination of materials and design features ensures reliable and precise operation in a wide range of applications.
