FAQ

High Precision Narrow Pinion from XRAY

The XRAY 305989 Aluminum Narrow Pinion Gear is engineered for hobbyists who want pinpoint gear alignment and consistent performance. Manufactured with advanced gear machining methods, it delivers very tight tolerances and excellent concentricity to keep operation smooth and quiet.

Lightweight Duraluminium Construction

Made from quality aircraft duraluminum, this pinion is both strong and light, measuring about 1.5 mm thinner and roughly 25% lighter than conventional pinions. The reduced mass improves drivetrain efficiency and can give quicker throttle response during competitive runs.

Hardened Surface and Run-In Finish

The pinion receives a dedicated hard-coating treatment that boosts wear resistance and preserves tooth profile over time. Carefully chamfered edges and a proper running-in routine help it mesh cleanly with spur gears, performing especially well with XRAY spur gears while cutting unwanted throttle 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.

How does the XRAY 305989 affect acceleration and top speed?

By lowering rotational mass and improving gear precision, this pinion can improve acceleration feel and drivetrain efficiency without changing gear ratios.

Will it pair with spur gears from other brands?

Yes, it is compatible with standard spur gears; adjust mesh carefully and check for smooth engagement, though it is optimised for XRAY spur gears.
