Precision 18T pinion engineered for the XRAY NT1

The XRAY 338518 is produced for the XRAY NT1 from 7075 T6 aluminium and receives a hardcoat to improve wear resistance. The 18-tooth design is manufactured to tight tolerances, promoting smooth rotation and minimised drivetrain buzz.

Long life and steady engagement

Intended for competitive users, the XRAY 338518 pairs a lightweight aluminium core with a protective coating to maintain tooth integrity under load. This keeps gear engagement stable through extended runs.

Quick to fit and easy to identify

Installation onto XCA clutchbells is straightforward with accurate threading for both standard and lightweight variants. Each pinion is marked with its tooth count so you can change gears quickly during setup changes.

Remark :

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.

Is this pinion suitable for high-power setups?

The hardcoated 7075 T6 construction is robust, but verify motor torque and drivetrain durability as high-power systems increase wear; monitor the pinion regularly in such setups.

How do I check for correct tooth wear?

Inspect tooth profiles for rounded edges, pitting or uneven contact patterns. Use a gear mesh indicator or paper test to confirm uniform tooth engagement across the face width.

Can the pinion be used with modified spur gears?

It can, provided the spur has compatible tooth geometry and the mesh is set correctly. Any spur modifications should be inspected to ensure they do not create hotspots or accelerated wear.
