The perfect match to our GT2 6mm wide belt. These pulleys are made of Aluminium and have a 5mm bore. An M3 grub screw locks it onto the shaft.
Comes with an M3x6mm grub screw.
20 teeth @ 2mm pitch = 40mm/rev.
When used with a 1.8° Stepper motor this gives the following step sizes:
Full stepping: 0.2mm/ step or 5 steps/mm
1/16th micro stepping : 0.125mm/step or 80 stepps/mm
