For CNC Spur Gear Kit Coated Stainless Steel, High Extruder Gears A3G4 One-piece shaft design ensures better concentricity of the gears, reduces eccentric rotation of the gears due to assembly, and guarantees more even filament delivery.
CNC hollow stainless steel gears, reduction gear design, high transmission ratio, to achieve greater extrusion torque, more wear-.
The driven gear adopts double ball bearings instead of the original needle bearings, with smaller clearance and higher .
Selection of high-strength mold steel as the material of the feed gear, the use of nano-coating treatment process, the hardness of the gear as a whole HRC value of 62-65; the hardness HV value of 1,000-1,200 greatly ensures the strength of the gear, abrasion resistance and resistance.

design, to the strength of the gear itself under the circumstances of the gear hollow gear excess material, reduce the weight of the gear.
