GT2 pulley 28 teeth Bore 5mm: maximum resolution for your axes
The 28-tooth GT2 toothed pulley is the choice of choice for those aiming for maximum mechanical resolution in positioning systems. Thanks to its reduced pitch diameter compared to the 20-tooth version, this component allows greater displacement accuracy for each individual motor step. With DHM, invest in ground components that ensure smooth movement, reducing vibration and optimising the performance of your 3D or CNC printer.
What is the 28-Tooth GT2 Pulley?
It is an aluminium transmission element with a rounded tooth profile (2mm pitch), specifically designed for high-precision linear motion. The 28-tooth design is engineered to maximise transmitted torque and offer superior resolution, making each micro-step of the stepper motor extremely effective in positioning the printhead or tool.
Why choose our 28-tooth GT2 pulley?
Manufactured with precision machining, this pulley offers key advantages for precision mechanics:
- High Resolution: The lower number of teeth ensures a shorter linear displacement per motor rotation, ideal for those looking for millimetre detail.
- Anti-Backlash Profile: The geometry of the GT2 tooth is optimised to eliminate backlash when reversing motion, ensuring smooth walls and dimensional accuracy in manufactured parts.
- Lightweight and Stable Construction: Entirely made of aluminium, equipped with a double side flange to keep the belt perfectly on axis even during sudden accelerations.
- Total Anchorage: Supplied with locking dowels for stable and secure attachment to the 5 mm motor shaft.
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 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 28-Tooth Pulley?
With its standard 5mm bore, it is the heart of synchronous drive systems in:
- Desktop 3D printers: Particularly suitable for X and Y axes where you want to increase printing precision compared to standard 20-tooth pulleys.
- Laser engravers and plotters: Ideal for machines requiring smooth movements and millimetre beam control.
- Precision Robotics: Ideal for actuators and automation systems that work in confined spaces and require high torque.
Package contains: 1 x GT2 pulley Ø 5mm 28 teeth H6
