High precision bearings built for hobby RC use

Built for hobby-grade models, the XRAY #930509 MR95ZZ bearings measure 5x9x3mm and give smooth rotation for common drivetrain and wheel assemblies. Their compact size makes them suitable for many 1/10 scale setups that demand consistent, low-friction operation.

Construction and lubrication details

These bearings are manufactured to tight tolerances for reliable service life. They are degreased and lightly lubricated with AeroShell Fluid 12 oil to reduce break-in time while preserving long-term smoothness. This preparation helps them run cleanly from first use.

Fitting advice

Press bearings squarely into clean housings and confirm axle alignment before final assembly. Keeping the bearing seats free of dirt and burrs will improve life and reduce noise.
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.

Which RC parts typically use 5x9x3mm bearings?

These 5x9x3mm bearings are often used in wheel hubs, differentials and some transmission shafts on 1/10 scale electric cars and buggies. They suit many common hobby applications.

How should I inspect bearings before reuse?

Check for side play, roughness when spinning and visible corrosion. If any roughness or slack is present, replace rather than reuse to avoid drivetrain wear.

What factory lubrication is applied to these bearings?

XRAY #930509 bearings are supplied degreased and lightly oiled with AeroShell Fluid 12 to balance smooth run-in with protection during storage.
