For Kobra3 Combo Extruder Nano Coated Gear Kit Hardened Steel Higher Precision One-piece Gear kit for Anycubic Kobra 3

About the Product: 1. Scope of application: For Kobra3 Combo Extruder 2. Processing technology: CNC 3. Material: POM and nano-coated mold steel 4. Features * One-piece shaft design ensures better concentricity of gears, reduces eccentric rotation of gears due to assembly, and ensures more uniform transmission of filaments by gears * CNC hollow POM gears, reduction gear design, high transmission ratio, and greater extrusion torque * The driven gear uses double ball bearings instead of the original needle bearings, with smaller gaps and higher precision * High-strength mold steel is selected as the material for the feeding gear, and nano-coating is used for surface treatment. The overall Rockwell hardness HRC value of the gear reaches 62-65; the surface hardness HV value reaches 1000-1200, which greatly guarantees the strength, wear resistance and corrosion resistance of the gear. *Helical gear design, better meshing performance, smoother gear transmission, and more linear transmission f
