Robust 21T Pinion for Demanding Use

The 3RAC-PG4821 offers a robust 21-tooth 48 pitch option for RC drivers seeking longevity. Manufactured from 7075 aluminum and finished with a hard coat, it is built to maintain gear geometry under repeated stress.

Performance and Compatibility

This pinion supports smooth torque delivery across a variety of 1/10 scale platforms using 48 pitch gears, helping to reduce unwanted backlash and improve responsiveness.

Why Choose 7075 Aluminum?

With superior strength characteristics, 7075 keeps the pinion dimensionally stable while remaining lightweight. The hard coating increases abrasion tolerance for extended operating life.

Installation Tips

Align the pinion carefully with the spur and set mesh to the manufacturer recommended clearance. Recheck set screws and mesh after a few runs to confirm secure installation.

Is this pinion a direct swap for existing 48 pitch setups?

It is usually a direct replacement for applications using 48 pitch pinions, but always match bore size, shaft type, and tooth count to your current setup before swapping.

How does the hard coating change wear characteristics?

The hard coat reduces surface wear and helps maintain tooth profile longer than uncoated alloys; however, proper mesh and lubrication remain essential for best results.
