What Are GT3 Pulleys?

Also known as “Gates Timing Pulleys,” these are a specific type of pulley designed to work in conjunction with a Gates timing belt, and used to transmit rotational power in synchronous belt drive systems.

They’re characterized by a precise tooth profile and engineered to facilitate the smooth and efficient transfer of power between the pulley and belt. This makes them ideally suited for demanding, high-performance applications, such as robotics, automated systems, and power tools.

The Powergrip GT3 is the newest iteration of the previous GT2 Belt Drive System, which makes it the optimal replacement for older belt technology. Its improved construction offers superior load-bearing capacity and a modified curvilinear tooth design meant to improve resistance to ratcheting, reduce vibration, and produce more even wear.

GT3 Timing Pulleys: The Benefits

High Strength-to-Weight Ratio

Our GT pulleys are made from a combination of lightweight plastics and metal insets, making them lightweight, but strong. These pulleys are made for high horsepower and torque-carrying capacity.

Low Cost

Compared to traditional alternatives, GT3 pulleys provide more power at lower costs. Simply switching from metal to plastic components can save you as much as 40% in material costs.

Precise Manufacturing

Our pulleys offer a deep tooth profile for superior load-carrying strength and greatly reduced ratcheting. This results in a quieter, more efficient, longer-lasting belt and pulley system.

Custom Solutions

If we don’t have a pulley that satisfies your specific needs, we can build a custom design pulley made expressly for your unique application.
