XRAY 930238 Ceramic Axial Ball-Bearing F3-8 3x8x3.5 Precision Upgrade  [XR-930238]

Precision upgrade for XRAY 930238 ceramic bearings

The XRAY 930238 Ceramic Ball-Bearing Axial F3-8 is a precision component made to refine the operation of your RC car's ball differential. It uses Si3N4 silicone nitride ceramic balls to deliver consistent wear resistance and efficient rolling performance.

Smoother rotation and reduced heat

Ceramic balls cut friction and vibration in the differential, which helps the drivetrain run cooler and smoother under load. That reduction in internal resistance supports higher sustained RPM and steadier throttle response.

Durability designed for demanding use

Installing the XRAY 930238 helps extend service intervals by resisting wear better than standard steel bearings. Its design keeps the differential functioning reliably when you push the setup on race days or long club sessions.
