Track-Proven Pinion Design

The XRAY 305970 Narrow Pinion Gear is designed to trim rotating mass without sacrificing performance. Made from aircraft duraluminum, it measures 1.5mm thinner and is roughly 25% lighter than conventional pinions, helping improve drivetrain efficiency.

Precision Gearmaking for Consistent Spin

Manufactured on a specially modified precision gear machine, the XRAY 305970 features very tight tolerances for superior concentricity. This precision reduces runout and promotes steady, predictable gear behaviour on the track.

Hard-Coated Finish for Wear Resistance

Each gear is chamfered, then treated with a hard-coating process that helps maintain tooth geometry and guard against premature wear. The finish contributes to longer service life under regular use.

Designed to Match Spur Gears Smoothly

The narrow profile is compatible with many spur gears and helps lower throttle on/off noise when mesh is set correctly. Pairing with XRAY spur gears often gives the quietest engagement and best feel.
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 motor shafts are compatible with this pinion?

Verify your motor shaft diameter and keying; the XRAY 305970 is intended for standard narrow-pinion setups but compatibility depends on your motor and clamp style.

Should I re-check mesh after the first run?

Yes, check mesh again after a short run as components can bed in; re-tighten motor mounting and confirm the hard-coated surface is seating correctly with the spur.

Is special maintenance required for the hard-coated surface?

No special maintenance beyond normal inspection for wear and correct mesh is needed; the hard coat helps protect the surface under typical hobby use.
