GT2 20 teeth pulley wheel for Belt 6mm Perlin passive idler pulley wheel bore 5mm

The GT2 20 Teeth Size Passive Idler Pulley (Smooth/Toothless) is a high-performance idler wheel designed for GT2 timing belts with 6mm width. It has a 5mm bore, compatible with most stepper motor shafts and smooth rods, and serves as a non-driven (passive) pulley for linear motion setups.

Unlike toothed pulleys, this Perlin-style idler has a smooth surface, making it ideal for use on the return or tension side of the belt system. It supports quiet and efficient belt movement without tooth engagement, helping reduce wear and maintain consistent belt alignment.
