For example, 2GT-200 has a 200mm (≈7.9\") circumference. To estimate the belt length needed, measure the center-to-center distance between your pulleys, multiply by 2, then add the circumferences of both pulleys. Always verify against your machine's specification sheet or measure the existing belt directly. When in doubt, size up slightly — a belt that is too short cannot be installed, while a slightly longer belt can typically be tensioned correctly.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eWhat does 2GT or GT2 mean on a timing belt?\u003c\/summary\u003e\n\u003cdiv class=\"hdiy-faq-body\"\u003e\n\u003cp\u003e2GT (also written GT2) refers to the Gates GT tooth profile with a 2mm pitch — the center-to-center distance between adjacent teeth. It features a curvilinear (rounded) tooth form that provides lower backlash and quieter operation compared to older trapezoidal profiles like T2.5 or T5. GT2 is the most common belt standard used in desktop FDM 3D printers and light-duty CNC machines.

Load capacity depends on operating speed, the number of teeth in mesh with the pulley, and pulley diameter. Wider belts carry higher loads — if your application requires more capacity, consider a wider belt variant.
