Curved teeth made from fiberglass-reinforced neoprene make these HTD (high-torque drive) belts stronger and quieter than belts with trapezoidal teeth. Also known as curvilinear and synchronous belts, their teeth have more surface contact than trapezoidal teeth, so they stay in contact with the pulley longer. This means these belts stay tight for accuracy required in applications with precise starts and stops, such as 3D printers, machine tool drives, and robotics.

Because these belts are fiberglass-reinforced neoprene, they resist stretching over time. They are also coated in nylon to reduce wear and improve grip.

These belts do not require end plates. Cut them to the length you need and attach them directly to your printer head or other equipment.

Also known as GT profile belts, belts with curved teeth minimize vibration and noise output. The teeth distribute pressure uniformly, so they wear evenly and last longer. Close engagement of the tooth and pulley offers more precise timing in heavy-load systems than trapezoidal teeth and HTD belts. Belts are neoprene, which is flexible and operates quietly. The fiberglass reinforcement on these belts add greater durability.
