Engineered Bearings for Reliable Rotation

The XRAY 931218 bearing set is aimed at hobbyists who want dependable rotation in drive trains and wheel hubs. With 12x18x4mm sizing, these bearings deliver steady performance and reduced rolling resistance for everyday use and spirited runs.

Sealed Steel with Light Oiling

Constructed from hardened steel and sealed to limit contamination, these bearings arrive lightly treated with AeroShell Fluid 12 to lower friction. The sealed design helps maintain smooth rotation and longer intervals between services.

Compatibility Across Models

These XRAY 931218 bearings suit a wide variety of RC kits and models requiring 12x18x4mm bearings, including examples like the RX8. They are a solid choice for replacing fatigued bearings or upgrading stock parts.
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.

Should I replace all bearings at once?

It is good practice to inspect matching bearings and replace worn ones in pairs or sets to keep handling consistent.

How often should I inspect these bearings?

Check bearings after dusty runs or every few race sessions; look for roughness or play and clean and relube as needed.

Will these improve lap times?

While bearings alone are not a lap-time miracle, smooth, low-friction bearings like the XRAY 931218 help reduce drivetrain losses and improve consistency.
