Upgrade Extruder Gear Kit for K1 Max 3D Printer All Metal Double Bearing Filament Drive Gear for K1 K1 Max K1C DLC Coated Extruder Upgrade Hardened Steel Gear

Características

• Precision Fit for K1 Series Printers:This extruder upgrade kit is purpose-built for K1, K1 Max, and K1C 3D printers, ensuring a direct replacement with no compatibility issues. Whether you're upgrading from a worn part or enhancing performance, it fits seamlessly with your existing extruder housing and motor assembly.
• DLC Coated Hardened Steel Construction:Both the main and reduction gears are CNC machined from hardened steel and treated with a diamond-like carbon (DLC) coating. This enhances surface smoothness, reduces friction, and dramatically extends gear lifespan—especially when running at high speeds or with abrasive filaments.
• Bearing Support for Smooth Feed:The drive gear includes dual internal bearings for enhanced axial stability. This reduces mechanical wobble and keeps filament feed precise, especially during retraction-heavy prints or when working with flexible filaments. Consistency and print quality improve significantly.
• Improved Torque and Accuracy:The integrated reduction gear setup boosts torque, making it easier for the extruder to push filament during long prints or when using higher-temperature materials. You'll see smoother extrusion, fewer under-extrusion lines, and more consistent first layers.
• All-Metal Reliability for Demanding Use:Unlike plastic or soft metal alternatives, this all-metal gear system resists wear and maintains performance under continuous, high-volume usage. Ideal for users running multi-hour print jobs, high-speed modes, or frequently switching materials like PLA, PETG, TPU, and nylon.
