Performance Bearings for Competitive RC

For consistent low-friction operation under race conditions, the XRAY 940816 high-speed ball bearings are a reliable upgrade. Supplied as two 8x16x5mm bearings, they are compatible with many RC drive systems and help keep rotational losses to a minimum.

Key Features

The bearings feature rubber seals to block contaminants and retain lubricant, and arrive pre-lubricated with a light grease for immediate use. The internal design uses an increased number of larger balls in the cage to improve load sharing and longevity in demanding running.

Easy Maintenance

These units are designed for straightforward servicing: side covers can be removed to clean the races and reapply lubrication, keeping performance consistent without complex disassembly.
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 do I verify correct fitment for my axles?

Measure the bore and outer race diameters on your hubs and compare to the 8x16x5mm specification to confirm these bearings will seat correctly.

What cleaning schedule is sensible for club tracks?

Inspect bearings after several runs and perform a full clean and relube whenever you notice increased drag or contamination, especially after dusty or wet meetings.

Can I replace the factory grease with oil for top speed?

Swapping to a low-viscosity oil can reduce drag at the cost of some long-term protection, so balance your choice with expected conditions and maintenance frequency.

Are the rubber seals removable for deep cleaning?

The side covers are removable for access; follow a careful cleaning routine to avoid displacing internal components while servicing.

Will these bearings improve battery life or run time?

Lower drivetrain friction from smooth bearings can give small improvements in efficiency, which may translate to marginal gains in run time depending on your setup.
