HUDY 294012 Aluminium ULTRA-LIGHT Pinion Gear Details

The HUDY 294012 Aluminium ULTRA-LIGHT pinion gear is a precision 12-tooth, 48-pitch component designed for careful R/C drivetrain setup. Fabricated from lightweight aluminium and treated with a hard coating, it helps cut rotating mass at the motor output while offering improved tooth surface durability for electric R/C systems.

The description explains technical intent rather than making broad performance claims: the lighter construction reduces rotational inertia and the hard coating increases resistance to tooth wear during high-speed or imperfectly meshed operation. Use this pinion when you require a 12T 48-pitch option and prefer aluminium over brass or steel for weight or handling reasons.

Fitment guidance: confirm correct tooth mesh and backlash when installing, secure the set-screw to the motor pinion flat with appropriate torque, and manually rotate the drivetrain to check spur engagement before running at full power. For gearing changes, alter pinion tooth count or spur size but maintain 48 pitch to preserve gear life.

Specifications

  • Item: Aluminium ULTRA-LIGHT pinion gear, hard coated, 12T, 48 pitch
  • Material: Aluminium, hard coated surface
  • Model Number: HUDY 294012
  • Compatibility: 48 pitch R/C pinion applications for motor and gearbox interfaces

Pick this pinion when a light, hard-coated aluminium 12T 48-pitch option best suits your motor and spur layout, and always check mesh and set-screw security as part of installation.
Remark :
Due to limited stock availability, please notice that some HUDY items may have to order from the factory and the ready time is around 8-12 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

What is the tooth count and pitch for this pinion?

It is a 12-tooth pinion intended for use with 48-pitch gear systems.

Why choose hard-coated aluminium over other materials?

Hard-coated aluminium offers weight savings that reduce rotational inertia while the coated surface helps resist wear compared with untreated aluminium; choose steel or brass if you need greater mass or different wear characteristics.

Will this match my motor and spur setup?

It matches systems using 48-pitch gears. Confirm motor shaft diameter, set-screw type, and ensure adequate mesh clearance before final installation.

How does changing pinion teeth affect final drive?

Altering the pinion tooth count changes the final drive ratio; increasing teeth raises top speed potential and reduces torque at the wheels, while decreasing teeth does the opposite. Always keep the pitch at 48 to avoid improper gear engagement.
