Precise and durable filament feeding

The Hosall hardened steel gear set for the Elegoo Centauri Carbon extruder increases service life and feed consistency. Dual-gear engagement ensures a firm grip on the filament and smooth extrusion even at higher speeds.

Why choose this set

• Hardened steel – significantly higher wear resistance than standard gearing.
• Dual-gear engagement – stable feed, less slipping, and even layers.
• Integrated shaft – minimizes runout and improves feeding accuracy.
• Precise CNC machining – clean tooth engagement, consistent print surfaces.
• For a wide range of materials – PLA, PETG, ABS, ASA, PC, TPU and also suitable for abrasive carbon fiber-filled blends.

Compatibility

• Elegoo Centauri Carbon (FDM).

Quick installation

Gear replacement is done directly in the toolhead/extruder. A detailed step-by-step procedure can be found in ELEGOO’s official guide “How to Replace the Gear of the Extruder.” After installation, we recommend checking the idler pressure setting.

Maintenance tip

When printing long-term with filled filaments (e.g., CF), regularly check the cleanliness of the extruder gearbox area; accumulated filament particles can cause slipping or clogs in the feed path. (Common community recommendation for the Centauri Carbon.)

Specifications

Note: The set is a direct replacement for the original gears in the Centauri Carbon extruder and requires no design modifications. For detailed disassembly/assembly, follow the instructions on the ELEGOO wiki.
