HRNSG3220 - 20t Steel 32p Pinion Gear 5mm Bore

This product is a precision machined steel pinion gear designed for RC vehicles using motors with a 5 mm output shaft. The hardened steel construction improves durability and wear resistance during high-load acceleration and sustained running. A 20-tooth count combined with 32-pitch gearing provides balanced gearing options for tuning speed and torque in many 1/10 and 1/8 scale applications. CNC machining ensures consistent tooth spacing for smooth gear mesh and efficient power transfer. A set screw mounting system secures the gear firmly to the motor shaft for reliable operation.

• Hardened steel construction increases wear resistance and extends service life under high load conditions.

• CNC machined gear teeth provide precise engagement with compatible 32-pitch spur gears for smoother drivetrain operation.

• 20-tooth configuration allows tuning of speed and torque depending on the spur gear and drivetrain setup.

• 5 mm bore fits common brushless motor shafts used in many 1/10 and 1/8 scale RC vehicles.

• Nitrided surface treatment improves hardness and corrosion resistance for longer gear life.

• Includes set screw for secure attachment to the motor shaft and reliable power transfer.

• Compatible with 32-pitch drivetrain systems commonly used in off-road trucks, buggies, and speed-run builds.
