Fine bearing upgrades using XRAY 930308

Serious RC builders who want consistent rolling will appreciate the XRAY 930308 ball-bearings. These 3x8x4mm bearings come as a pair, prepped degreased with a light coating of AeroShell Fluid 12 oil to aid initial break-in.

How they improve drivetrain feel

Manufactured to strict tolerances, these bearings minimise friction and increase predictability in steering and throttle response. They work well when you need a reliable, low-resistance rotation point in gearboxes and axles.

Where to fit them

Great for both road and dirt rigs, the XRAY 930308 ball-bearings slot into many common hubs and diff assemblies. Durable finishing helps them stand up to regular club use and frequent packing.
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 swap these into my spare parts kit?

Absolutely. Keeping a pair of XRAY 930308 bearings in your spares is smart, as the 3x8x4mm size fits many drive locations.

Will factory grease interfere with performance?

These arrive degreased and lightly oiled to reduce initial drag. If you apply heavy grease it can slow them, so use a light bearing oil for best results.

Are they sealed or open bearings?

These are prepared for low friction and typical hobby use; inspect your kit diagram to confirm placement and any seal requirements.

Best lubricant to use after initial run-in?

A light, low-viscosity bearing oil is recommended to maintain spin without adding drag; avoid heavy greases in high speed locations.
