Creality 3D LD-002H starre koppeling

Precision-machined from aluminum alloy, this rigid coupling delivers a backlash-free connection between the 5 mm stepper motor shaft and 8 mm lead screw of your Creality LD-002H resin 3D printer. Its 19 mm outer diameter and 25 mm length ensure a compact yet robust interface that elevates Z-axis accuracy for sharper, more consistent prints.

Overview

The Creality LD-002H Rigid Coupling is a direct replacement or upgrade for the stock coupler, engineered to maintain perfect shaft alignment under load. Four M3 set screws lock both shafts securely, preventing slippage and rotational play that can cause layer shifts or Z-wobble. The silver anodized finish resists corrosion and wear, ensuring long-term reliability in demanding print environments.

• Eliminates backlash for smoother Z-axis motion
• High torque transmission without flex or lag
• Corrosion-resistant aluminum alloy construction
• Precision bores: 5 mm and 8 mm for exact fit
• Four set screws provide a secure, maintenance-free hold
