2 Meter GT2 Timing Belt Kit with 20-Tooth Pulleys

The GT2 system features a 2mm pitch, which refers to the distance between the centers of two adjacent teeth. This fine pitch allows for higher resolution and smoother motion, crucial for detailed 3D printing and precise CNC operations, ensuring accurate and consistent movement.

The included GT2 pulleys have a 5mm inner bore diameter. They are designed to fit snugly onto standard 5mm diameter motor shafts, commonly found in NEMA 17 stepper motors used in 3D printers and small CNC machines, ensuring secure power transfer for motion systems.

Fiberglass reinforcement provides excellent tensile strength, minimizing stretching and deformation under load. This maintains belt tension and accuracy over time, reducing backlash and ensuring consistent, high-quality output for intricate digital fabrication projects, improving overall reliability and print precision.

The pulleys are secured to the motor shaft using two set screws, typically tightened with an Allen wrench. Position the pulley, align the set screws with any flats on the shaft if present, and tighten them firmly to prevent slippage during operation, ensuring stable power transmission.

Yes, this GT2 timing belt and pulley kit is versatile. It can be utilized in various DIY projects, robotics, custom CNC builds, laser engravers, and other linear motion systems where precise and reliable power transmission is required, offering broad applicability for makers.
