HUDY 294012 Aluminium ULTRA-LIGHT Pinion Gear - Hard Coated - 12T/48  [HSP-294012]

HUDY 294012 Aluminium ULTRA-LIGHT Pinion Gear

The HUDY 294012 Aluminium ULTRA-LIGHT pinion gear is a 12-tooth, 48-pitch pinion produced for precision R/C drivetrain adjustments. Built from lightweight aluminium with a hard-coated surface, it targets small reductions in rotating mass while maintaining a wear-resistant contact surface for prolonged service life in electric R/C setups.

The design purpose is technical clarity rather than performance claims: the low mass helps reduce rotating inertia at the motor output, and the hard coating improves resistance to tooth wear where mesh quality or high RPM duty cycles are factors. Use this pinion when you need a specific 12T count on a 48-pitch motor gearbox interface and want a durable aluminium option instead of steel or brass.

Installation notes: check tooth meshing and backlash when fitting this pinion to your motor shaft, verify set-screw torque against the motor pinion flat, and confirm alignment with the spur gear at static rotation before full-power runs. For tuning, change pinion tooth count or spur size to adjust final drive ratio; keep the pitch match at 48 to avoid premature wear.

Choose this pinion when a lightweight aluminium 12T 48-pitch option with hard-surface protection fits your motor and spur configuration, and always verify mesh and set-screw security during installation.
