Precision Ceramic Balls for Smoother Runs

The XRAY 930220 Ceramic Ball set suits pilots wanting quieter, smoother drivetrain action. Manufactured from Si3N4 silicon nitride ceramic, these balls prioritise long service life and low friction for high RPM conditions.

Benefits Compared to Steel Balls

Ceramic balls are roughly 60% lighter than steel, cutting rotating inertia and boosting responsiveness. They typically endure 3-5 times longer under similar use and their polished surface lowers friction and component wear.

Practical Performance Gains

  • Durability: Excellent resistance to wear and corrosion supports longer maintenance intervals.
  • Efficiency: Less internal drag promotes smoother power transfer and cooler operation.
  • Lightweight: Reduced rotating mass helps with throttle response and lap times.
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.

Are these balls suitable for off-road and on-road cars?

They work well in both environments as long as the size matches your diff or bearing application. Ceramic gives benefits in high speed and high load situations alike.

Will ceramic balls need special races or seals?

Standard steel races generally work fine, but ensure clean contact surfaces. Good sealing keeps grit out, which is important for ceramic longevity.

How do I check for wear on ceramic balls?

Inspect for surface pitting or flat spots and measure for roundness; replace if you detect damage to avoid scoring the races.
