Durable XRAY 385621 pinion built for consistent gear engagement

The XRAY 385621 is a steel 21-tooth, 48-pitch pinion aimed at hobbyists who want a reliable drivetrain component. The precision tooth profile helps maintain steady gear mesh and reduces the chance of intermittent binding.

Engineered chamfers and run-in surface

Chamfered tooth edges reduce initial friction and limit premature chipping, while the pre-run finish means the gear seats quickly in typical setups, cutting down break-in time.

Swap-in durability for frequent use

This pinion is suitable for replacing worn gears or upgrading to a more durable option. Proper installation and periodic checks will keep it performing well under varied driving conditions.
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.

Does this work with my 48-pitch spur?

The XRAY 385621 is made for 48-pitch systems and meshes with standard 48-pitch spurs, though you should verify spur tooth condition and mesh settings after fitting.

Should I use thread lock on the set screw?

Light blue thread lock can help secure the pinion on steel shafts; avoid heavy thread lock if you anticipate frequent changes to pinion size.

How often should I inspect the pinion?

Check teeth and mounting after hard sessions or if you notice unusual noise. Replace at the first sign of tooth deformation to protect the spur.
