They are designed for GT2 open-loop timing belts in 6 mm (0.24 in) and 10 mm (0.39 in) widths, with bore options ranging from 5 mm to 10 mm (0.20–0.39 in) to suit a wide range of motor shaft diameters.

NEMA 23 motors commonly use an 8 mm shaft. If your motor shaft is imperial (e.g., 1\/4 inch), choose the 6.35 mm bore.

A 6 mm belt is standard for most desktop 3D printers (Ender, Voron, etc.) and lighter CNC builds. A 10 mm belt carries higher load capacity and is preferred for wider-format CNC routers, laser cutters, or any axis where belt stretch under load is a concern.

They resist tooth deformation under belt tension, maintain dimensional accuracy at elevated temperatures (such as near a heated print bed), and do not creep over time.

The GT2 32-tooth profile with 5 mm bore and 6 mm belt width is a standard specification used on many popular FDM printers including the Creality Ender series and Voron 2.4 \/ Trident builds.
