2GT Timing Belt 16 Teeth 5mm Pulley

The GT2 pulley with 16 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. 2GT used in linear drive with Linear Motion Small Backlash Positioning Accuracy.

Two set screws (M3 Allen Cap) are provided to lock/fasten the pulley firmly to any 5mm diameter motor's shaft such as NEMA Bipolar Stepper Motor. Not to worry, most of the 3D printer stepper motor's shaft diameter is 5.0mm :) It is full aluminum construction that offers very light and very durable.
