The GT2 Pulley and Belt offers precise motion control at very low cost. The GT2 series of belts and pulleys are designed specifically for precise linear motion. They use a rounded tooth profile that guarantees that the belt tooth fits smoothly and accurately in the pulley groove, so when you reverse the pulley direction, there is no room for the belt to move in the groove. 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 40 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.
These pulleys are popularly used in 3D Printers and DIY CNC Machines.
