HUDY 294012 Aluminium ULTRA-LIGHT 12T 48-Pitch Pinion Gear  [HSP-294012]

HUDY 294012 Aluminium ULTRA-LIGHT Pinion - 48 Pitch

The HUDY 294012 Aluminium ULTRA-LIGHT pinion gear is a 12-tooth, 48-pitch pinion made for precise R/C drivetrain adjustments. Machined from lightweight aluminium with a hard-coated finish, it aims to reduce rotating mass while offering a more wear-resistant contact surface for extended service life in electric R/C setups.

The design intent is technical clarity rather than performance promises: the lower mass reduces rotational inertia at the motor output, and the hard coating helps resist tooth wear under high RPM or imperfect mesh conditions. Fit this pinion when you require a 12T count in a 48-pitch motor-to-gearbox interface and prefer a durable aluminium option versus steel or brass.

Installation notes: verify tooth meshing and backlash when fitting this pinion to your motor shaft, check set-screw torque against the motor pinion flat, and rotate the drivetrain by hand to confirm alignment with the spur gear before full-power runs. For tuning, alter pinion tooth count or spur size to change final drive ratio while keeping a 48 pitch match to avoid premature wear.

Select this pinion when a lightweight aluminium 12T 48-pitch option with a hard-surface finish matches your motor and spur arrangement, and always confirm mesh and set-screw security during installation.
