XRAY 305930 Narrow Pinion Built for Accuracy

The XRAY 305930 Narrow Pinion Gear is aimed at modelers who demand accurate tooth alignment and dependable service. Constructed from aircraft grade aluminium, the pinion is 1.5mm narrower and roughly 25% lighter than standard units, helping to reduce drivetrain inertia.

Precision Production and Hardcoat Surface

Machined using XRAY modified precision gear equipment, each pinion holds tight tolerances to maximise concentricity. Tooth edges are chamfered and the part is finished with a hardcoat to enhance wear resistance and ensure steady operation.

Suitability and Performance Notes

This narrow pinion pairs well with spur gears and is particularly effective alongside XRAY spur gears to lower throttle noise and smooth power transfer. It is supplied ready for immediate installation.
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 replace a full width pinion without changes?

Yes, it replaces a standard 30T pinion without altering gear ratio. Check mesh and mounting hardware to ensure correct alignment after fitment.

Are spare grub screws or adaptors needed?

Most installations use standard grub screws. Keep a spare screw and ensure it is tightened to the correct torque to avoid slippage on the motor shaft.

How do I check for concentricity after installation?

Spin the motor slowly and observe runout against a fixed point or use a dial indicator. Any wobble indicates improper seating or a damaged bore that should be addressed before use.
