Precision Bearings from XRAY 940509

For modelers seeking reduced drag and reliable rotation, the XRAY 940509 High-Speed Ball Bearings are designed to perform. This pair of 5x9x3mm bearings suits many RC drivetrain and wheel applications.

Durability through Improved Ball Arrangement

The design uses more and larger balls in the cage to improve load distribution and strength under strain. Rubber seals provide protection from contaminants and a light oil coating of AeroShell Fluid 12 helps preserve running smoothness.

Simple Servicing for Regular Upkeep

Side covers remove easily so you can access the internals for cleaning and relubrication. From club racing to casual driving, these bearings deliver the accuracy and durability expected in common RC setups.
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 components commonly use 5x9x3 bearings?

This size is common in wheel hubs, motor mounts and gearbox shafts across many 1/10 and 1/12 scale kits. Check your manual for exact fitment listings.

How should I store bearings when not in use?

Keep them in a dry, dust-free box and avoid exposure to moisture; the factory oil helps, but long term storage benefits from occasional inspection and re-oiling.

Are sealed bearings worth fitting to vintage models?

Sealed bearings like these reduce maintenance and protect older components, making them a sensible upgrade for many restored or maintained vintage RC cars.
