High precision pinion from XRAY 305991

The XRAY 305991 Aluminum Narrow Pinion Gear is a 41T component engineered for competitive RC applications where accuracy and longevity matter. Its hardcoated surface increases wear resistance while aircraft-grade duraluminum keeps rotating mass low to help improve throttle response and overall efficiency.

Reliable mesh and quieter drive

Produced on precision gear machines, the XRAY 305991 delivers tight tolerances and excellent concentricity. The chamfered tooth edges and even hardcoating help sustain smooth engagement with spur gears and reduce audible throttle noise, especially when used with XRAY spur gears.

Slim, lightweight profile for faster response

This 41T pinion is part of a 40T to 50T 64-pitch family and uses a thinner duraluminum section to cut weight by roughly 25% compared to standard pinions. The reduced thickness lowers drivetrain stress and supports sharper acceleration, making it a solid upgrade or replacement choice.
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.

Is the XRAY 305991 compatible with non XRAY spur gears?

Yes. The pinion uses a 64-pitch profile so it will mesh with other 64-pitch spurs, but optimal quietness and fit are achieved with XRAY spur gears.

How do I set gear mesh with this narrow pinion?

Start with a small paper shim to establish backlash, then tighten the mesh until you see a slight tooth contact pattern. Recheck under power and after a short run to confirm stability.

What maintenance keeps the pinion lasting longer?

Keep the gear clean of grit, inspect the hardcoat for wear, and confirm shaft seating and set screw torque regularly. Replace if you notice significant flank damage.
