HRNSG3219 - 19t Steel 32p Pinion Gear 5mm Bore

This drivetrain component transfers power from the motor to the spur gear in RC vehicles using a 32 pitch gear system. Hardened steel construction provides improved resistance to wear and fatigue during high speed or high torque operation. Precision CNC machining ensures consistent tooth geometry for smooth gear mesh and efficient power delivery. A nitrided surface treatment increases hardness while helping resist corrosion over time. The gear is designed for brushless motors that use a 5 mm output shaft commonly found in many performance RC platforms. Its compact profile supports drivetrain tuning by allowing adjustments to the vehicle’s final gear ratio. The durable steel design makes it suitable for both replacement use and performance upgrades.
