These pulleys will fit 8mm smooth rod and 8mm motor shafts like those found on our NEMA23 Motors.
    GT2 pulley, 8mm bore, 20 teeth.

    This style pulley known as Ultimaker Pulley in 3d printing industry. But the true it's a universal 16 teeth or 20 teeth GT2 Pulley because the bore is large as 8mm, so you need a wider HUB than the 5mm bore pulleys.

    Do you know?
    The GT2 6mm width open end Belt and GT2 20 Teeth Pulley combination is the best of the best possible belt & pulley combo for all MendleMax and all Reprap variant 3D Printers. And it is less prone to backlash due to the way the rounded teeth mesh up. Square toothed belts and pulleys just always seem to have that little bit of play that is impossible to calibrate out of your printer. Our GT2 pulleys and belts are the best choice for very precise positioning. Simply swapping out your square tooth belts and pulleys for these GT2 profile belts and pulleys is a VERY cost effective way to upgrade your 3D printer and improve print quality! The GT2 round tooth belt is also quieter than square toothed designs.

  • GT2 Pulley 20 Teeth 5mm Bore (GT2)
    The gt2 pulley with 20 teeth or grooves is one of the best choices for 3d printer construction. Compared with the T2.5 or MXL timing pulley, the gt2 pulley tooth profile is anti-backlash. Why? The rounded teeth of this tooth and belt are engaged together longer providing a smoother transition between teeth. This is what you need for your 3D printer. A smaller pulley with less teeth moves less belt per revolution. Not great for printing speed but with a 200 step motor and a 20 tooth pulley that means every single tooth on your belt can move in ten discrete steps! That\'s going to make for some really nice prints!

    Specifications are as following:

    Pitch: 2mm
    Tooth: 20
    Bore: 5mm. 8mm Bore gt2 20 teeth pulley is also available from Stock.
    Flange: Dual
    Material: Aluminum
    Max. Belt Width: 7mm
