Creality Ring Synchronous Belt 640mm for Ender 3 S1, CR-10 SE

Description

The Creality 640mm Ring Synchronous Belt is a high-precision GT2 closed-loop timing belt designed for dual Z-axis or CoreXY synchronization systems. Engineered for use in 3D printers like the Ender 3 S1 series and CR-10 SE, it ensures both sides of the gantry move in perfect unison—reducing layer shifts, improving print accuracy, and stabilizing vertical motion.

Features

• Closed-loop GT2 design: 2mm tooth pitch for high-resolution motion control
• Pre-cut to exact 640mm loop length—no trimming needed
• 6mm width ensures durability and grip on pulleys
• Reinforced tensile cords to resist stretching and maintain long-term precision
• Compatible with OEM pulleys and mounts used in Creality’s Z-sync assemblies
• Flexible rubber body: Quiet, smooth operation with minimal backlash
• Easy to install: Plug-and-play fit with Creality's factory stepper & gantry setups
