ARA310966 Safe-D5 Mod1 Pinion Gear (19T)

Arrma ARA310966 19T Mod1 Safe-D5 Pinion Gear is a precision steel pinion gear designed for radio‑controlled vehicles and similar hobby drivetrain systems. It has 19 teeth with a Mod1 gear pitch, which lets it mesh accurately with compatible spur gears to provide smooth and efficient power transfer. The gear includes a ‘Safe‑D’ style D‑shaped bore that matches a 5 mm motor shaft so drive and braking engagement are maintained even if the set screw loosens. It also comes with a threaded set screw and an e‑clip for secure attachment to the motor shaft, making it durable and reliable for high‑speed or high‑torque RC use.
