Featherweight Narrow Pinion for Performance

The XRAY 305931 narrow pinion is made from high-grade aluminium to cut weight without sacrificing durability. With 31 teeth and a profile that is 1.5mm thinner and roughly 25% lighter than standard pinions, it is aimed at pilots wanting sharper acceleration and lower rotational inertia.

Precision Gearmaking Process

These pinions are turned on XRAY's specialist gear machines to maintain tight concentricity and consistent tooth form. Chamfered tooth edges and a dedicated hard-coating process help the gear resist wear and stay true over many sessions.

Designed for Smooth Mesh and Low Noise

While compatible with many spur gears, the XRAY 305931 performs particularly well with XRAY spurs to reduce throttle buzz and improve drivetrain smoothness. Installation is straightforward so you can set up and run quickly.
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.

Will this pinion fit my existing spur gear?

It fits a wide range of spur gears, but confirm tooth count and bore size on your spur and motor shaft. Best results are seen when paired with XRAY spur gears.

Does the thinner section reduce durability?

Despite being slimmer and lighter, the aluminium construction and hard-coating maintain adequate durability for racing use; normal inspection intervals are recommended.

Any setup tips for quieter operation?

Set a correct gear mesh, use shims if needed, and ensure motor alignment to reduce vibration and keep noise to a minimum.
