HUDY 294012 ULTRA-LIGHT Aluminium Pinion for 48-Pitch

The HUDY 294012 Aluminium ULTRA-LIGHT pinion gear is a precision 12-tooth, 48-pitch component intended for drivetrain tuning in electric R/C cars. Made from light aluminium and finished with a hard coating, it aims to reduce rotating inertia and offer improved tooth surface durability under demanding conditions.

The description focuses on technical application rather than absolute performance claims: the reduced mass lowers rotational inertia at the motor output and the hard-coated surface helps resist wear where mesh quality or high RPM duty are factors. Use this pinion when a 12T 48-pitch aluminium alternative is required instead of brass or steel.

Fitting advice: set and confirm proper tooth mesh and backlash, fasten the set-screw to the motor flat with appropriate torque, and rotate the assembly by hand to check alignment before power runs. To alter final drive ratio, change pinion teeth or adjust the spur while ensuring the pitch remains 48 to avoid premature gear wear.

Choose this pinion when you need a lightweight, hard-coated aluminium 12T 48-pitch option for your motor and spur configuration, and always validate mesh and set-screw security at installation.
