Innovative Power Transmission Solutions

At Torque Transmission, we specialize in the design and manufacturing of off-the-shelf and custom power transmission components, with a focus on plastic and plastic-metal power transmission products for fractional horsepower applications.

Our catalog includes a variety of standard-size timing pulleys as well as made-to-order pulleys, all of which promise superior performance and durability. And, our policy is to manufacture a timing pulley that arrives finished, meaning your component will be ready to work from the outset without any other third-party modification.

What Are Timing Pulleys?

Timing pulleys are mechanical components essential to the timing and synchronization of drive systems, specifically the timing of two or more shafts. They’re designed to transmit rotational power from one shaft to another, ensuring that power is transferred smoothly and efficiently.

The wrong size or a low-quality timing pulley can lead to issues such as vibration, component damage, and machine downtime.

HTD 3mm, 5mm, 8mm

We offer high torque drive (HTD) timing pulleys that have precise tooth profiles and high torque capacity, in three different pitches:

  • 3mm for high-speed, low-torque applications and high belt speeds
  • 5mm for medium-speed, medium-torque applications and moderate belt speeds
  • 8mm for low-speed, high torque applications and lower belt speeds


GT3 Timing Pulleys

We also sell the GT3 Series of high-torque pulleys, designed for applications that demand high load-carrying capacity, as well as precision indexing or registration. We offer a wide range of timing pulleys with varying face widths. Our selection includes 6mm, 9mm, and 15mm face width options, and we can provide pulleys with as few as 12 teeth to as many as 120 teeth.


Why Torque Transmission Timing Pulleys?


Lightweight and Durable

Our pulleys are made using a combination of lightweight plastics and metal insets for an incredibly high strength-to-weight ratio, low inertia, and chemical and shock resistance.


Whatever your specific industrial needs may be, our team can modify a standard timing belt pulley or create a custom design for your particular applications.


Plastic is cheaper, lighter, and easier to mold than metal. By switching from metal to plastic components, our customers have realized cost savings ranging from 20% to 40%.

Locally Made

All of our products were made and manufactured at our facility in Ohio.
