GT2 Synchronous Pulley 20 Teeth Hole 4mm H6: Precision Linear Motion
20-tooth GT2 timing pulleys set the standard for those seeking a perfect balance between speed and precision in motion control. Designed specifically for precision applications, these pulleys drastically reduce positioning error, ensuring smooth and constant transmission. With DHM, invest in selected mechanical components to ensure maximum reliability for your automation and 3D printing systems.
What is the GT2 Synchronous 20-Tooth Pulley?
It is an aluminium drive element with a rounded tooth profile and 2mm pitch. Unlike the old trapezoidal profiles, the GT2 synchronous system has been designed for linear motion: the special tooth geometry allows the belt to enter and exit without excessive friction, guaranteeing quiet operation and a longer component life.
Why choose our GT2 H6 pulley?
Manufactured with high quality machining, this pulley offers real advantages for your projects:
- Anti-Backlash Profile: The tooth shape is optimised to eliminate mechanical backlash during reverse motion, ensuring flawless repeatability.
- Mechanical Stability: Equipped with a double lateral flange, it keeps the belt perfectly centred on the sliding surface, preventing backlash during sudden changes of direction.
- Aluminium Construction: Lightweight and corrosion-resistant, ideal for reducing the inertia of moving axles without sacrificing strength.
- Secure Fixing: Supplied with locking dowels included for stable and durable anchorage on the rotating shaft.
Note on manufacturing 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 bore). 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 20-Tooth Pulley?
With its standard 4mm bore, it is the ideal component for popular stepper motors (such as NEMA 17) in various contexts:
- 3D Printers: It is the heart of X and Y axis movement for consumer and professional models requiring high reliability.
- CNC and Laser Engravers: Ideal for small pantographs where tenth-of-a-millimetre precision is crucial to the end result.
- Robotics and Prototyping: Excellent for automation systems requiring constant and silent synchronous drives.
Package contains: 1 x GT2 SYNCHRONOUS pulley Ø 4mm 20 teeth H6
