GT2 16-Tooth Timing Pulley for 6mm Belt, 4mm Bore

A GT2 timing pulley ensures precise, slip-free power transmission from stepper motors to the timing belt. This synchronized movement is crucial for maintaining accuracy in 3D printer axes, directly impacting print quality by preventing layer shifts and ensuring smooth, repeatable motion.

This pulley is specifically designed for use with GT2 timing belts that have a width of 6mm. The 2mm pitch of the GT2 profile ensures optimal engagement with the rounded teeth of the pulley, providing excellent anti-backlash performance for high-precision applications.

Yes, its high-quality aluminum construction offers excellent rigidity and low inertia, making it suitable for high-speed linear motion systems. The precise machining and GT2 tooth profile minimize vibration and backlash, contributing to stable performance even at elevated operational speeds in CNC or robotic setups.

The 4mm bore diameter is a common size for shafts on NEMA 17 stepper motors, which are widely used in 3D printers and small CNC machines. This makes the pulley directly compatible with many standard motor configurations, simplifying integration into existing or new projects.

Aluminum pulleys offer superior durability, heat resistance, and dimensional stability compared to plastic variants. They are less prone to wear, deformation under load, or thermal expansion, leading to more consistent performance, higher precision, and a significantly longer service life in demanding applications.
