GT2 Idler Pulley – 20 Tooth, 5 mm Bore, 6 mm Width

Product Description

The GT2 idler pulley with 20 teeth, 5 mm bore, and 6 mm width is designed to guide GT2 timing belts smoothly and accurately in 3D printers, CNC machines, and motion systems.
Specifically, the 20-tooth profile ensures proper belt engagement, which helps maintain consistent belt tracking. As a result, motion accuracy improves while vibration and belt wear are reduced.

Moreover, the smooth rotation of the idler pulley allows the belt to move freely without damaging the teeth. At the same time, the 6 mm width makes it fully compatible with standard GT2 belts. Therefore, this pulley is an excellent choice for high-speed CoreXY, Cartesian, and Voron-style printer setups.
