Smooth Operation with XRAY 930407 Bearings

For maintaining peak performance in club racers and weekend buggies, the XRAY 930407 MR74ZZ ball-bearing set is a dependable choice. These bearings measure 4x7x2.5mm and are supplied as a handy two-pack for quick replacements.

High Tolerance Construction

The XRAY 930407 MR74ZZ bearings are prepared to promote smooth rotation and extended service life. They arrive degreased and lightly oiled with AeroShell Fluid 12 to reduce break-in friction while preserving precision tolerances for consistent running.

Typical Uses

These bearings suit many RC roles, from wheel hubs to drivetrain shafts. Keep a pair on hand for maintenance or when assembling a new chassis to ensure reliable mechanical support where tight tolerances matter.
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.

How often should I re-lubricate these bearings?

Inspect after heavy sessions and re-lube lightly every few runs or when you notice roughness. Use a thin oil for speed or a heavier grease for longevity depending on use.

Will these fit other brands of hubs and axles?

The 4x7x2.5mm size is common; check your parts diagram or measure the bore and shaft to confirm compatibility before ordering.

Can I run them in wet or dusty conditions?

They perform well in clean conditions but should be serviced more often in dust or water. Consider shields or seals for heavy off-road use.
