GT2 pulley 20 Teeth Hole 5mm: compactness and precision in a reduced flange
The GT2 pulley with reduced flange is the advanced solution for designers who have to operate in extremely confined spaces. Thanks to the optimised design with fixing dowels integrated into the pulley body, this component reduces axial space requirements on the motor shaft, while maintaining the exceptional accuracy of the GT2 synchronous profile. With DHM, choose mechanical innovation to optimise every millimetre of your design.
What is the GT2 Reduced Flange Pulley?
It is a special variant of the classic 20-tooth pulley, made of aluminium with 2mm pitch. Its distinguishing feature is its 'slim' profile: unlike standard pulleys, which have an external collar for the beads, this model integrates the fastening system directly under the teeth or in an ultra-compact body. This allows the pulley to be brought closer to the motor body or other structural components, maximising space efficiency.
Why choose the version with internal grub screws?
Designed for precision assembly, this pulley offers unique advantages for modern mechanics:
- Minimum footprint: Ideal for compact machines where space on the drive shaft (NEMA 17) is limited or where the belt must run very close to the bearings.
- GT2 Synchronous Profile: Ensures no backlash and superior smoothness of movement, essential for high-quality 3D printing and laser engraving.
- Improved Balance: The compact design reduces suspended masses on the shaft, helping to reduce vibration during high speeds.
- Invisible Fixation: Internal grub screws provide a powerful grip on the 5mm shaft without side protrusions that could interfere with other mechanical parts.
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 stated 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 Reduced Flange Pulley?
Its specific geometry makes it indispensable in particular technical scenarios:
- Ultra-Compact 3D Printers: Perfect for small extrusions or portable machines where every millimetre of axis saved counts.
- Systems CoreXY Evolved: Where the passage of belts requires millimetric alignment in confined spaces.
- Robotics and Micro-Automation: Excellent for robotic actuators and joints where component density is high.
