Achieve professional-grade motion accuracy with our GT2 20-Teeth Timing Pulley. Engineered for high-performance 3D printers and DIY CNC machines where precision is non-negotiable.
The GT2 (2mm pitch) profile is the industry standard for Open Source Fabrication due to its rounded tooth profile, which eliminates backlash and ensures smooth transitions. This specific pulley, with a 6.35mm (1/4″) bore, is ideal for high-torque motors often found in robust builds like the My-CoreXY or customized laser engravers.
Why this Pulley stands out:
-
CNC Machined: Made from high-quality aluminum alloy for high strength and low inertia.
-
Dual Set-Screws: Features two M4/M3 grub screws to ensure a secure lock on the motor shaft, preventing slipping during high-acceleration prints.
-
Perfect Pitch: Designed for 6mm wide GT2 belts, providing a 1:1 engagement that reduces vibration and noise.
-
Resolution Power: The 20-teeth configuration is the “sweet spot” for 3D printing, offering excellent steps-per-mm resolution.

Consultant’s Pro-Tip: When building your My Machines project, ensure the set screws are tightened against the flat side of the motor shaft (D-shaft). This prevents the pulley from spinning freely under load, which is a common cause of “ghosting” or layer shifts in Prototyping projects.
📦 Package Includes: 1x GT2 20T Pulley (5mm Bore) and 2x Set Screws.
