High-Quality Ceramic Balls for RC Drivetrains

The XRAY 930220 Ceramic Ball set provides a simple upgrade path for hobbyists wanting tougher, lower friction components. Produced from Si3N4 silicon nitride ceramic, these balls help reduce wear and maintain smooth operation under strain.

Advantages Over Conventional Steel

Being about 60% lighter than steel equivalents, ceramic balls reduce rotating inertia and improve responsiveness. They are reported to last roughly 3-5 times longer in similar conditions and their smooth finish lowers friction and surface wear.

Core Benefits at a Glance

  • Durability: Strong wear and corrosion resistance supports prolonged use.
  • Efficiency: Lower friction improves rotational smoothness and reduces energy loss.
  • Lightweight: Less rotating mass aids quicker acceleration and better control.
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.

Will these balls affect diff tuning?

You may need to tweak diff oil or preload slightly to match the reduced internal friction, but the change is generally positive for consistency.

How do I maintain ceramic balls for longevity?

Keep them clean and lightly greased, and check for micro damage during routine servicing. Avoid abrasive contaminants that can abrade the races.

Are ceramic balls compatible with steel cages and races?

Yes, in most cases standard steel races and cages are compatible, but ensure seating surfaces are free of burrs and contamination before installation.
