Torque Transmission offers three types of metric timing pulleys: 3 mm pitch HTD, 5mm pitch HTD, and 8 mm pitch HTD. All three types of pulleys are precision, injection molded and glass reinforced. This design offers efficient power transmission without slip or backlash.

**The Pulley Design**

Our metric timing pulleys are fabricated from nylon with metal inserts for reinforcement, which takes advantage of the lightweight properties of nylon while gaining the advantages of a metal-to-metal connection at the hub and shaft. All three pulleys also offer a high strength-to-weight ration and low inertia because of their unique design.

**Features of the Metric Timing Pulley**

Torque Transmission's Metric Pitch HTD Timing Pulleys are injection molded to rigid standards for true design pitch, giving you the precision you need. They offer a number of valuable features, including:
