A1 Mini Extruder Gear, with Aluminum Alloy Handle,A1 Mini xirbbo Extruder Gear Assembly CNC POM Nano Coated Hardened Steel for Bambu Lab A1 Mini Extrusion Head Gear 3D Printer Accessory

["Shipping List:Gear kit* 1 set","Weight: 30g","Applicable models: Bambu Lab A1 mini, not for x1/ x1c/ x1e/ p1p/ p1s.","The handle material is changed to aluminum alloy, which prolongs the service life of the handle and enhances the texture.","(1) One-piece shaft design ensures better concentricity of the gears, reduces eccentric rotation of the gears due to assembly, and safeguards the gears for more even filament delivery.","(2) Helical gear design, better meshing performance, smoother gear transmission, more linear power transmission. Transmission overlap is large, long meshing time, large contact area, so that the stress becomes smaller, thus improving the gear's carrying capacity, as well as extending the service life of the gear.","(3) Selection of high-strength mold steel as the material of the feed gear, the use of nano-coating surface treatment process, the Rockwell hardness of the gear as a whole HRC value of 62-65; the surface hardness HV value of 1000-1200 greatly ensures that the gear's strength, abrasion resistance and corrosion resistance, improve the gear's load-bearing capacity, and extend the service life of the gear."]
