High Precision Ceramic Upgrade for the XRAY X4 2025

Owners seeking crisper drivetrain response for the XRAY X4 2025 can fit the XRAY 309003 ceramic bearings as a direct replacement for stock steel units. The 12-piece kit focuses on delivering lower friction and improved consistency lap after lap.

Why Use Ceramic Balls

The bearings use Si3N4 silicon nitride ceramic balls which reduce mass and offer greater resistance to corrosion and wear compared to conventional steel. This means smoother rotation and less energy lost to bearing drag.

Factory Prep and Lubrication

Bearings are supplied degreased and lightly treated with AeroShell Fluid 12 oil so they perform well from first fit. That initial lubrication assists with tolerance stability and keeps the bearings running true until routine servicing.

12 Bearings for Key Positions

This set of twelve covers the principal bearing positions on the XRAY X4 2025. Replacing worn steel bearings with these ceramic parts can reduce drivetrain noise and help maintain consistent handling characteristics.
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.

Can I use XRAY 309003 bearings in vintage cars?

Compatibility depends on bearing dimensions. If the old car uses the same inner and outer diameters, the bearings will fit, but always confirm sizes before installing.

How do I clean these bearings?

Remove bearings from the car, clean with an appropriate solvent, dry fully and then apply a light bearing oil. Avoid abrasive cleaning methods that can damage races.

Are ceramic bearings louder than steel?

Ceramic bearings can sound slightly different but are not necessarily louder. Proper lubrication and clean conditions are the main factors that affect noise levels.
