GT2 Pulley 20 Teeth Hole 5mm H9 PowerGrip: Increased power and precision
GT2 PowerGrip profile pulleys represent excellence in linear motion transmission for those who need to handle higher loads without sacrificing millimetric precision. This version, with an enlarged 9 mm seat, is designed to accommodate wider belts, ensuring a larger contact surface area and optimal stress distribution. With DHM, choose high-performance components to transform the power of your engine into smooth, uncertainty-free movement.
What is the GT2 PowerGrip 20-Tooth Pulley?
It is a high-quality aluminium transmission element with 2mm pitch, specifically engineered for the PowerGrip system. The distinguishing feature of this model is its 9mm internal useful width, which allows the use of 9mm reinforced belts (instead of the standard 6mm). This configuration drastically reduces the 'stretch' of the belt under load, improving positioning repeatability even under severe working conditions.
Why choose the H9 PowerGrip version?
Manufactured to exacting tolerances, this pulley offers concrete mechanical advantages for your automation:
- Increased Load Capacity: The 9 mm seat allows higher torques to be transmitted, ideal for heavy axes or sudden accelerations.
- Reduced Backlash: The tooth profile is designed for perfect coupling with the belt, eliminating backlash when reversing motion.
- Lateral Stability: The reinforced double flange ensures that the belt remains perfectly centred, minimising lateral friction and edge wear.
- High-Tightness Fixing: The 5mm hole is calibrated for drive shafts NEMA 17, with locking dowels included for stable and durable anchoring.
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 GT2 H9 pulley?
Due to its robustness and oversized profile, it is the ideal component for:
- High-End 3D Printers (Voron, V-Core): For those wishing to upgrade their mechanics using 9mm belts for greater axis rigidity.
- CNC and Professional Laser Engravers: Where belt stability is essential to maintain precision over large working areas.
- Robotics and Actuators: Perfect for systems requiring reliable synchronous transmissions under significant inertial loads.
