GT3 pulley 20 Teeth Hole 8mm: superior power and precision

GT3 profile timing pulleys represent the evolution of the synchronous drive system, designed for those who are not satisfied with standard performance. Compared to the GT2 system, the GT3 profile offers greater load capacity and even higher precision, making it the preferred choice for professional applications requiring flawless motion control. With DHM, you are guaranteed mechanical components selected to maximise the performance of your system.

What is the GT3 20-Tooth Pulley?

It is a high-quality aluminium transmission component with 3mm pitch. The GT3 profile was developed to provide a more even stress distribution across the belt teeth, drastically reducing wear and the risk of 'tooth jumping'. With an 8mm bore, this pulley is perfectly compatible with the most popular stepper motors in the world of automation and advanced 3D printing.

Why choose our GT3 pulley?

Manufactured using precision machining, this pulley is distinguished by superior technical characteristics:

• Higher transmissible torque: The 3mm pitch allows it to handle higher workloads than 2mm systems, ideal for heavy axes or high speeds.
• Optimised geometry: The tooth design ensures smooth meshing, reducing vibration and guaranteeing excellent operating silence.
• Stability and Safety: The double side flange prevents axial displacement of the belt, while the included retaining screws ensure a firm grip on the motor shaft.
• Durability: The wear-resistant aluminium ensures a long service life even under intensive use.

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 inner 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 GT3 20-Tooth Pulley?

Due to its robustness and increased pitch, it is the ideal component for:

• High-End 3D Printers: Perfect for large format machines or systems that require high acceleration without pitch loss.
• Industrial Automation: Used in conveyor and positioning systems where mechanical precision must be durable.
• CNC and Robotics: Excellent for small actuators and robots that need smooth and powerful motion transmission.
