GT2 pulley 20 Teeth Hole 5mm Black: the standard of precision in a Black Edition version
20-tooth GT2 timing pulleys are the beating heart of the world's most popular drive systems. This black finish version not only guarantees the millimetre accuracy required for linear motion control, but also adds a touch of professional design to your mechanics. With DHM, choose components that combine the reliability of the GT2 synchronous profile with a curated aesthetic, ideal for open-source machines and high-end custom projects.
What is the GT2 20-Tooth Black Pulley?
It is an aluminium transmission element with a rounded tooth profile (2mm pitch) and black surface anodising treatment. The 20-tooth configuration is the ideal compromise between displacement speed and resolution, making it the standard choice for most stepper motors NEMA 17. The matt black colour complements it perfectly with the anodised aluminium profile frames, creating a clean, technical look.
Why choose the 20 Teeth Black version?
Manufactured with CNC precision, this pulley offers both functional and aesthetic advantages for your build:
- Protective Anodised Finish: The black treatment increases surface resistance to wear and protects the aluminium from oxidation over time.
- Torque/Speed Balance: The primitive diameter of the 20-tooth version allows rapid acceleration while maintaining excellent positioning accuracy.
- Anti-Backlash Profile: Designed to eliminate mechanicalbacklash, it ensures that every change of direction is smooth and without height uncertainty.
- Aesthetic Integration: Perfect for "Total Black" assemblies or for those wishing to visually distinguish components from different machines or axes.
Note on production tolerances
We work to ensure the highest quality consistency, however, due to possible variations between production batches, actual measurements may differ from those given in the data sheet by ±2 mm (except for internal hole). If your project requires specific dimensions or precise millimetre tolerances, we recommend that you contact us prior to purchase for direct verification of stock measurements.
When to use the GT2 Pulley 20 Teeth Black?
The standard 5mm bore and universal profile make it indispensable for:
- 3D Printers (Standard and Custom): Ideal for those who want to maintain standard firmware settings (80 step/mm) while improving the aesthetics of the machine.
- CNC Desktop and Laser: Perfect for bevel gearboxes and drives where the pulley is visible and needs to co-ordinate with a professional design.
- Hobbyist automation: Excellent for sliding systems where clean aesthetics and precision are key requirements.
Package contains: 1 x GT2 SYNCHRONOUS pulley Ø 5 mm 20 teeth H10 - colour black
