Quiet and consistent rotation from XRAY

Keeping your model crisp on-track starts with good hardware. The XRAY 13x20x4mm ball bearings are engineered for dependable rotation and longevity. Supplied in pairs, they make a tidy replacement for worn bearings or a simple upgrade during routine servicing.

Carefully pre-treated bearings

These bearings arrive degreased and lightly greased to balance free movement with protection. That treatment helps them settle quickly and keeps performance steady across varied RC conditions.

Ideal uses for club and casual setups

XRAY ball bearings are a solid match for both race-oriented and casual machines. Fit them to wheel hubs, pulleys or gearboxes to cut friction, minimise wear and keep handling predictable on different surfaces.
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.

Are these bearings a direct swap for common 13x20x4 parts?

Yes, the 13x20x4mm size is a standard fit and should replace like-sized bearings without modifications.

Should I remove the factory grease before use?

They are supplied degreased and lightly greased; you can run them as supplied or add a small amount of your preferred bearing oil for specific conditions.

Do these bearings handle wet conditions?

Light splashes are manageable, but prolonged exposure to water will shorten bearing life unless regularly cleaned and re-greased.
