### 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 force. The transmission overlap is large, the meshing time is long, and the contact area is large, which reduces the stress, thereby improving the bearing capacity of the gear and extending the service life of the gear. * Lightweight design: hollow out the excess material of the gear while ensuring the strength of the gear itself, thereby reducing the weight of the gear.
