The 2GT-3mm Series of belts and pulleys has more aggressive teeth than its little brother the 2GT. 2GT-3mm has the same tooth profile as 2GT, but is with a 3mm pitch instead of 2mm. It is commonly known as GT3. 2GT-3mm is more suited to higher torque applications, making it perfect for your automation projects. These 2GT-3mm 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.
