HRNSG219 - 19t Steel 32p Pinion Gear 5mm Bore

This 19‑tooth 32 pitch pinion gear is CNC machined from hardened steel for enhanced wear resistance and long service life when paired with a matching 32 DP spur gear on RC vehicles. The straight‑cut gear teeth are precisely spaced to match standard 32 DP gear sets, ensuring smooth power transfer from the motor to the drivetrain. The bore is sized for 5 mm motor shafts, making it compatible with many brushless and brushed motors used in 1/10 and 1/8 scale cars and trucks. A 4 mm set screw is included to secure the gear to the motor shaft and minimize slippage under high torque. Hardened steel construction resists tooth wear and strip under load compared to softer materials. Installation requires only basic tools and proper mesh setup with the spur gear for optimal performance. Ideal for upgrading from stock gears or adjusting gearing for speed or torque needs.
