Adafruit Aluminum GT2 Timing Pulley - 6mm Belt - 20 Tooth - 5mm Bore
For precise motion control, GT2 belts and pulleys offer excellent precision at a great price. This pulley is meant for use with GT2 6mm wide belts only - MXL belts will slip due to the different tooth profile.
This pulley has 20 teeth, and a 5mm inner bore. Two set screws can be used to attach it firmly to any 5mm diameter shaft such as one of our stepper motors. Full aluminum construction means these are very light and very durable.
