GT2 20T Timing Pulley — 6.35mm (1/4") Bore, 6mm Width

20-tooth GT2 timing pulley — 2 mm tooth pitch, 6.35 mm (1/4") bore, for 6 mm-wide GT2 belt.

The 6.35 mm bore drops straight onto a 1/4" motor or jackshaft — handy where a metric bore won't fit. GT2's precise tooth profile gives low-backlash motion for CNC and 3D-printer drives. Pairs with a larger pulley for a belt reduction, or runs 1:1. Used on the Millennium Mills Milo and any GT2 motion system.
