상품 특징

• Applicable Model: The extruder gear is replacement for Kobra 3 max extruder, adopting hollow design, reducing weight while ensuring its own strength.
• Integrated Shaft: The extruder gear features integrated shaft design for higher concentricity, reducing gear eccentric rotation during assembly, ensuring uniform filament delivery.
• High Performance: CNC hollow POM gear adopts reduction gear design, with high transmission ratio, and large extrusion torsion. The driven gear adopts double ball bearings instead of the original needle roller bearings, with smaller clearance and higher accuracy.
• High Hardness: The gear adopts high strength hardened steel and is treated with nano coating, the overall hardness HRC value reaches 62-65, the surface hardness HV value reaches 1000-1200, ensuring the strength, wear proofing, and erosion proofing.
• Improved Gear Performance: The helical gear design ensures better meshing performance, smoother gear transmission, and more linear force delivery, improving load bearing capacity, extending the service life.
