Competition-Grade Narrow Pinion Gear

The XRAY 305927 Narrow Pinion Gear offers a slimline upgrade for pilots chasing cleaner drivetrain response. Made from aircraft-grade duraluminum, it is 1.5mm narrower and about 25% lighter than traditional pinions, lowering rotating mass where it matters.

Superior Concentricity and Surface Treatment

Turned on a specially modified machine for exact tolerances and concentricity, this pinion features chamfered teeth and a hardcoat that helps the gear resist wear and preserve tooth accuracy over many runs.

Optimised for Smooth Operation with Spur Gears

It meshes well with general spur gears and works particularly quietly with XRAY spur gears, delivering smoother engagement and less drivetrain vibration from the start.
Remark :
Due to limited stock availability, please notice that some XRAY items may have to order from the factory and the ready time is around 4-6 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 pitch and tooth count is this made for?

The item is produced for 48 pitch systems with the stated tooth count; ensure your spur and pinion share the same pitch for correct engagement.

Can the hardcoat be polished?

Light polishing can remove surface marks but avoid aggressive abrasion that might thin the hardcoat; inspect tooth profiles before and after any polish.

Will it fit common motor shafts?

Fit depends on your motor shaft diameter and set screw arrangement. Verify shaft size and secure the pinion properly to avoid slippage.

How often should I inspect the pinion?

Check the pinion after high impact or abrasive runs and during routine maintenance to catch wear early and keep optimal mesh.

Is this a direct replacement for stock pinions?

In many cases yes, provided the shaft and pitch match your stock pinion; follow correct installation steps to ensure proper alignment.
