Adafruit 1252 Aluminum GT2 Timing Pulley – 6mm Belt – 20 Tooth – 8mm 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 8mm inner bore. Two set screws can be used to attach it firmly to any 8mm diameter shaft. Full aluminum construction means these are very light and very durable.
