Sherpa CNC POM helical gear with nano coating by Fysetc

What it is: Fysetc Pom gears used in their CNC sherpa extruder, comes with shims, bearing and shaft. Gears are helical and coated to improve their hardness.    Features The integrated shaft design ensures better concentricity of the gears, reduces eccentric rotation of the gears due to assembly, and ensures that the gears transport filament more evenly.  CNC hollow POM gear, reduction gear design, high transmission ratio, achieving greater extrusion torque  The driven gear uses double ball bearings instead of the original needle bearings, with smaller clearance and higher precision. Use high-strength mold steel as the material of the feeding gear, and use nano-coating 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 ensures the gear Strength, wear resistance and corrosion resistance. Helical gear design, better meshing performance, smoother gear transmission, and more linea
