GT2 Close-Loop 188mm Long & 6mm-Width Rubber Timing Belt for 3D Printer

The GT2 Close-Loop 188mm Long & 6mm-Width Rubber Timing Belt is a durable and precision-engineered belt designed for high-efficiency motion transfer in 3D printers and CNC machines. This belt features a circular arc GT2 tooth profile with a 2mm pitch, which provides superior accuracy and load-carrying capability over traditional HTD belts—especially in linear motion applications.

This closed-loop (endless) design with a total loop length of 188mm makes it ideal for synchronized motion in systems using small pulleys, such as extruder carriages and Z-axis movements. The 6mm width ensures strong torque transmission while maintaining flexibility. Constructed from high-strength rubber with a fiberglass-reinforced core, it resists stretching and maintains consistent performance across long-term use.
