HRNSG21M06 21T Steel Mod 0.6 Pinion Gear 5mm

This drivetrain component transfers motor power to the spur gear in RC vehicles that use 0.6 module gear pitch systems. Hardened steel construction provides durability and resistance to wear under high speed and high torque conditions. Precision CNC machining helps maintain accurate gear mesh and smooth power transfer during operation. The gear is designed for motors with a 5 mm shaft and includes a conversion sleeve for compatibility with 1/8 inch shafts. A longer hub design increases contact area with the motor shaft to help improve stability under load. Laser marked tooth identification allows quick verification of gear size during setup or maintenance. The compact design supports performance tuning by adjusting gear ratios in compatible RC vehicles.
