This GT2 Close-Loop 188mm Long & 6mm-Width Timing Belt for 3D Printer. The Power Grip GT2 system is an extension of the HTD system with greater load-carrying capacity.

HTD drive clearance, using small diameter pulleys, is approximately four times greater than an equivalent GT2 timing belt drive.

As smaller diameter pulleys are used, the clearance required to operate properly is increased. Circular arc tooth profile, tooth space is small, suitable for straight line driving.
