MK8 Brass Extruder Drive Gear 26T for 3D Printer

The MK8 Brass Extruder Drive Gear 26T is a high-precision filament feed gear designed to ensure smooth, slip-free filament extrusion in your 3D printer. Featuring a robust 26-tooth profile, this gear provides exceptional grip on standard 1.75mm and 3.0mm filaments (such as PLA, ABS, PETG, and flexible TPU), preventing under-extrusion and improving overall print quality. It is an essential upgrade or replacement part for maintaining consistent extrusion calibration.

Constructed from high-quality, wear-resistant brass, this drive gear is built to withstand continuous operation without wearing down. It features a standard 5mm inner bore, making it directly compatible with NEMA 17 stepper motor shafts commonly used in Creality Ender, Anet, Makerbot, and custom DIY 3D printers. The integrated M3 grub screw ensures a secure, slip-free lock onto the motor shaft flat, providing reliable torque transfer during high-speed printing.

Features:

• High-Precision 26 Teeth: Specially engineered tooth profile delivers excellent grip and prevents filament slipping.
• Durable Brass Construction: High wear resistance ensures a long operational lifespan compared to standard gears.
• Standard 5mm Bore: Fits perfectly on NEMA 17 stepper motor shafts.
• Secure M3 Lock: Includes an M3 grub screw for a tight, slip-free attachment to the motor shaft.
• Compact & Lightweight: Weighs only 4.8 grams, minimizing rotational inertia on the extruder motor.
• Universal Compatibility: Works seamlessly with MK8 extruder blocks, Makerbot, Creality Ender series, and DIY setups.
