About This

• [Precision Upgrade Kit] The 30-second quick-change design is compatible with the Elegoo Centauri /Centauri Carbon 2 hotend extruder. 0.4mm layer height accuracy is improved by 65%, with torque fluctuations less than 1rpm, significantly improving the success rate of complex model printing.
• [Extremely Long-Life Core] The SKD11 alloy steel drive shaft is vacuum heat-treated to HRC60+, and TD roller coating forms a 2-5μm vanadium carbide layer. This ensures stable dimensional accuracy even at 200°C, and its lifespan exceeds three times that of conventional components.
• Durable All-Metal Upgrade: Crafted from high-quality steel and precision heat-treated to a surface hardness of up to 55HRC, it's wear-resistant and durable, ensuring a more stable lead-gear system for your printer's creative journey.
• It effectively prevents rust while maintaining long-term gear lubrication, reducing noise and enhancing the user experience, ensuring every print is silky smooth. Say goodbye to issues like wire skipping and clogging, and elevate print quality to a higher level. Details determine success.
• [Self-lubricating Bearing] The PTFE-based GFM bearings have a friction coefficient of 0.03 and offer a maintenance-free life of 2000 hours even without lubrication. This reduces handle operating force by 40%, ensuring long-term use without binding.
