Smooth running performance with XRAY bearings

When you want to keep your RC model operating at peak efficiency, the right components matter. The XRAY 13x20x4mm ball bearings are produced to deliver steady performance and long service life. Supplied as a pair, these bearings are a practical option for routine drivetrain maintenance and part swaps.

Prepped for reliable rotation

Each bearing is carefully degreased and treated with a light grease to ensure consistent rotation and reduced break-in time. That preparation helps these bearings perform well under load and keeps tolerances tight across a range of RC setups.

Where to use these bearings

XRAY ball bearings suit a variety of hobby uses, from club racing to weekend trail runs. Fitting them into hubs, differentials or gearbox shafts helps lower friction, cut wear on mating parts and keep steering and power delivery more predictable.
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.

Will these bearings fit standard 13x20x4 housings?

Yes. These 13x20x4mm bearings follow common sizing so they fit standard housings and shafts that accept that dimension.

How do I look after the bearings for best life?

Clean debris from the seals, reapply light bearing grease if needed, and avoid water immersion to keep the bearings running smoothly.

Can I use these in high-speed gearboxes?

They are suitable for many drivetrain applications, but check load and speed requirements for your particular gearbox before relying on them for extreme high-speed setups.
