Accurate Narrow Pinion Designed by XRAY

The XRAY 305989 Aluminum Narrow Pinion Gear suits modelers who expect steady, precise gear interaction. Manufactured with refined gear machining, it achieves tight tolerances and superior concentricity for quieter, more reliable operation.

Robust Yet Reduced Mass Build

Produced from aircraft-grade duraluminium, this pinion balances toughness with a lower weight profile, being approximately 1.5 mm thinner and around 25% lighter than many standard pinions. The lighter unit helps reduce drivetrain inertia and sharpens throttle response.

Protective Hard Coating and Smooth Break-In

Each pinion receives a protective hard coating that enhances resistance to wear and keeps tooth geometry stable over time. Chamfered teeth and a recommended running-in procedure promote seamless meshing with spur gears, particularly complementing XRAY spur gears to lower audible drivetrain noise.

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 maintenance does the XRAY 305989 require?

Regular inspection for wear and ensuring correct mesh are key; clean debris and recheck alignment after hard sessions to preserve performance.

Is this pinion a direct replacement for other narrow pinions?

It fits standard 64P narrow setups, but confirm tooth count and shaft fit before swapping; it is engineered to pair especially well with XRAY spurs.
