The GT2 pulley is the perfect component to forever eliminate the hated backslash between the belt and the gear teeth. It's mandatory in the X and Y axes in order to get the best superficial finishings in a 3D printer or belt-driven CNC machine.
This pulley uses two perpendicular grub screws (included) in order to get a better fitting. This way it's not necessary to use flat shaft motors.
With a bore diameter of 6,35mm, this pulley is compatible with Nema23 motors.
Although technically they can be used with up to 11mm belts, this pulley works beautifully with 10mm synchronous belt.
The price is for one unit.
