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
High torque
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.

Good fit no problems

Well made, close to overpriced

In the case of my motors the bore was too small, however i didn’t use the issue motors but 3 i already had. i had purchased this pully to finally sort out the ongoing problem i was having with an allan key for the pully i had. in the event the grub screw was a size i already had an allan key for, so i drilled out the central hole and now consider the over, somewhat obliquely but sorted.
