Creality Sermoon D3 kit de correia síncrona para eixo Y

When the Y-axis of your Creality Sermoon D3 starts to slip or lose precision, print quality suffers. This synchronous belt kit restores consistent motion, eliminating layer shifts and banding caused by worn or damaged belts and pulleys.

Who is it for

This kit is for Creality Sermoon D3 owners who need to replace a stretched belt, worn pulley, or noisy idler. It is also useful for preventative maintenance, ensuring the printer continues to produce accurate parts over time.

Main features

• Complete Y-axis motion solution: includes GT2 belt, motor pulley, and two smooth idlers.
• Fiberglass-reinforced rubber belt resists stretching for long-term accuracy.
• Aluminum alloy pulleys with 625ZZ bearings provide smooth, quiet operation.
• Direct replacement for original Creality Sermoon D3 parts—no modification needed.
• Mounting hardware included for straightforward installation.

Tips

Before installation, clean the Y-axis rail and check for debris. Tension the belt so it produces a low twang when plucked—too tight causes premature wear, too loose leads to ghosting. After replacement, run a test print to verify layer alignment.
