The GT3 Series of belts and pulleys has more aggressive teeth than its little brother the GT2. The GT3 Series is more suited to higher torque applications, making it perfect for your automation projects. These GT3 Pulley’s have a 6.35mm Bore making a perfect partnership with NEMA23 Stepper Motors
The high torque series have been specially designed to accept a 9mm wide belt for use with our high torque reducer applications. These come in either a 1/4″ variant to go on the motor shaft. Or 8mm to go on an ACME Lead Screw.
