Upgrade Note for XRAY Owners

The XRAY 309002 ceramic ball bearing set is a straightforward way to reduce drivetrain friction and noise. Supplied for XRAY T2 and T3 models, the pack contains ten 5x10x4mm bearings and four 10x15x4mm bearings to replace common wheel and shaft bearings.

Advantages of Ceramic Bearings

Ceramic bearings lower rolling resistance and typically run cooler than steel equivalents, which helps with motor efficiency and consistency over a race. They also resist corrosion and abrasion better, giving longer service intervals when cared for correctly.

Materials and Finish

The XRAY 309002 set uses Si3N4 silicone nitride ceramic balls and each bearing is degreased and lightly lubricated with AeroShell Fluid 12 oil. The result is a low-friction, precision-prepared bearing suitable for competition use.
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 these bearings to replace all steel bearings in my car?

You can replace steel bearings where the dimensions match 5x10x4mm or 10x15x4mm. For sealed diffs or special housings check compatibility before swapping every bearing.

What is the best cleaning method?

Use a dedicated bearing solvent and a lint free cloth, then dry fully and apply a small amount of light oil. Avoid heavy grease that can negate ceramic benefits.

Are they worth upgrading for club racing?

For regular racers seeking reduced friction and quieter operation, ceramic bearings like the XRAY 309002 are a sensible upgrade. They offer measurable drivetrain gains when maintained properly.
