GT2 – 20Teeth 5mm Bore Idler Pulley
GT2 Bore 5mm 20 Teeth Timing Aluminum Pulley Fit GT2-6mm Open Timing Belt
The GT2 pulley wheel 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.
