2 x Precision Aluminum GT2 Pulleys with 2 meters (78-3/4") of GT2 Open Timing Belt and 2 Aluminum Bering Flanged Idlers. Pulleys come with hex screws and tool.

Quality belt reinforced with fiberglass threads.

For 3D Printing applications, GT2 2mm belt system works better than T5, T2.5, it gives better smoothness and accuracy of positioning, resulting in better printing quality. GT2 timing belt system especially suited for linear movement and positioning applications.

• Timing Belt:

Highest quality precision timing belt, not cheap Chinese replacement. Made from NEOPRENE - Synthetic Rubber reinforced with fiberglass cords for superior strength. Neoprene - oil-resistant substitute for natural rubber, was invented by DuPont scientists on April 17, 1930. Balanced combination of polymer's properties:

    Resists degradation from sun, ozone and weather
    Performs well in contact with oils and many chemicals
    Remains useful over a wide temperature range
    Displays outstanding physical toughness
    Resists burning inherently better than exclusively hydrocarbon rubbers
    Outstanding resistance to damage caused by flexing and twisting
