💡 What is a ceramic bearing used for in precision hobby gear and RC models?
These bearings are handy in small, high-speed assemblies where friction and heat are a concern.
- high rigidity and low friction for precise motion - lightweight and heat resistance improve performance in hot environments - zirconia balls with ceramic races minimize wear and extend life - easy drop-in replacement for metal bearings in many hobby projects
