XRAY NT1 thrust bearing stopper (spring steel) by Arrowmax AM-NT1-330003  [AM-NT1-330003]

Thrust bearing stopper overview

This Arrowmax AM-NT1-330003 thrust bearing stopper is an RC-scale spring steel clip designed for use on the XRAY NT1 chassis. It is intended to secure axial position of thrust/ball bearings in drivetrain assemblies where precise preload and retention matter during setup and maintenance.

The part’s role is narrow and technical: hold a thrust bearing in place on a shaft or carrier, resist axial movement under load, and provide a repeatable contact point for bearing preload adjustments. Made from spring steel, it balances flexibility for installation with sufficient spring tension to keep bearings located without loosening during normal RC use.

Installation notes: the stopper is a simple clip-style component; verify orientation and bearing seating before final assembly, check for free rotation after fitting, and inspect for wear periodically. In tuning contexts it helps maintain consistent bearing preload when swapping gears, diff rebuilds, or during high-rev drivetrain checks on NT1 setups.
