Features: Integrated shaft design to prevent metal gear from detaching, ensuring improved gear alignment and reducing eccentric rotation for consistent filament delivery. Eliminate issues such as inconsistent extrusion and weak filament grip commonly encountered in extruders. Precision-driven gear with double ball bearings, offering reduced clearance and enhanced accuracy. Constructed with high-strength mold steel for the feeding gear, featuring nano-coating for superior surface treatment. Achieves an overall Rockwell hardness (HRC) of 62-65 and a surface hardness (HV) of 1000-1200, greatly enhancing gear strength, wear resistance, and corrosion resistance, thereby extending gear lifespan and improving load capacity. Specification: Compatible with: Ender-3 S1/Ender-3 S1 Pro/Ender-3 S1 Plus/CR-10 Smart Pro/Ender-3 V3 SE/Ender-5 S1/CR 200B Pro and CR-M4, and more. Package Size: 8 x 6 x 2 cm / 3.1 x 2.3 x 0.7 in Package Weight: 20 g / 0.7 oz Packing List: 1 x Sprite Extruder Gear Kit
