The 2GT Pulley series is specifically designed for linear motion, using a rounded tooth profile it ensures the belt tooth fits precisely in the pulley groove. When reversing the pulley direction there is no room for the belt to move in the pulley groove, this greatly reduces the backlash improving motion consistency.
These pulleys are specially machined to closely match our Genuine Gates Unitta 2GT Timing Belt, practically to perfection. They are manufactured by the same manufacturers behind parts used on the most popular 3D Printer brand in the world.
The 30 Tooth 2GT Pulley is perfect for v-slot projects. The pulley has been designed so the belt system works with the pulley on either side of a 20mm extrusion profile, and will not hit the edges of the extrusion.
