Gearmaking Accuracy and Balance

The XRAY 305970 Narrow Pinion Gear targets precise, lightweight gearing for better drivetrain behaviour. Cast from aircraft duraluminum, it is 1.5mm narrower and approximately 25% lighter than common pinions, which lowers inertia for improved throttle feel.

Controlled Manufacturing for Tight Concentricity

Produced on a specially modified precision gear machine, the XRAY 305970 is held to exacting tolerances to ensure outstanding concentricity. This attention to detail reduces runout and helps keep engagement smooth under load.

Chamfered Edges and Hard-Coated Protection

Following machining, each pinion is chamfered then finished with a hard-coat to shield the tooth surfaces. The treatment preserves the gear profile and diminishes wear from repeated spur contact.

Optimised for Spur Gear Interaction

The narrow tooth profile works well with a broad range of spur gears and helps reduce throttle on/off clatter, especially when matched with XRAY spur gears for the best balance of quiet running and precise engagement.
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 my stock pinion without other mods?

In many cases it will swap in directly, but confirm tooth count, shaft fit and motor mount clearance before installing the XRAY 305970 to avoid mesh issues.

How much quieter is a narrow pinion in practice?

A narrower, well-machined pinion like the XRAY 305970 typically reduces throttle on/off noise when mesh is correct, with less audible clatter compared to thicker, less precise pinions.

What should I inspect regularly on this pinion?

Regularly check tooth condition, mesh alignment and mounting security; the hard-coating helps durability but inspection will catch any alignment or wear issues early.
