3M GT2 Timing Belt & 2PCS GT2 Timing Pulley 20T Bore5mm 3D Printer RepRap Prusa

Specification:
GT2 Pulley? Teeth 20 Groove Width 7mm Total Width 16mm Bore 5mm Flange dual Material Aluminium
GT2 Belt Black Pitch GT2 Width 6mm Length 3M Material Fiber Reinforced Rubber Features: GT2 timing belts and compatible pulleys(GT2 pulley) are popular choices for RepRaps and RepStraps.
The GT2 series of belts are designed specifically for linear motion. They use a rounded tooth profile that guarantees that the belt tooth fits smoothly and accurately in the pulley groove, so when you the pulley direction, there is no room for the belt to move in the groove.
For best performance you want at least 6 teeth in contact with the pulley at any given time. That minimizes the chance of the belt slipping, and helps reduce backlash even further. In practice that means you want a minimum of a 12 tooth pulley, and I usually try to get at least 16 teeth.
