The GT2 20T pulley is designed specifically for linear motion. This GT2 Timing pulley has 20 teeth and an 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. 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. The GT2 8mm pulley wheel with 20 teeth or grooves is one of the best choices for 3d printer construction.
