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.

Strong enough to replace roller chain, these timing belts combine the high strength of a curved tooth with high-strength carbon fiber reinforcement. Belts are abrasion-resistant urethane, so they don’t create dust while they run. They have carbon fiber reinforcement, which has ultra-high-strength, low stretch, and excellent shock resistance. The teeth are nylon coated to protect the wear surface and minimize friction.
