Technical Overview of the 3RACING 3RAC-PG4848 Pinion

The 3RACING 48 Pitch Pinion Gear 48T is CNC-oriented in design and produced from 7075 aluminum, then surface treated with a hard coating to increase resistance to abrasive wear. It provides consistent tooth form and predictable engagement for competition tuning.

Performance and Durability Details

With tight dimensional control and a hard finish, the 3RACING 48T pinion reduces micro-motion at the mesh interface and extends service intervals. Its profile supports stable gear ratios under transient loads common in racing environments.

Compatibility and Setup Guidance

Intended for 1/10 scale drivetrains, this pinion integrates with standard spur gears; precision mounting and correct mesh are essential to leverage its hard-coated surface and avoid premature wear on mating components.

What tolerances are critical when fitting this pinion?

Ensure shaft runout is minimal and the pinion bore fits the shaft without play; even small radial errors affect mesh and wear rates.

How does the hard coating affect gear break-in?

The coating reduces initial surface deformation, so perform controlled break-in with conservative loads to seat the mating surfaces evenly.

Recommendations for competitive tuning with this pinion?

Use incremental tooth count changes and monitor motor temps and spur wear; the 3RACING 3RAC-PG4848 excels when mesh and motor parameters are tuned together.
