💡 What is a ceramic ball bearing used for in small precision systems?

Ceramic bearings are handy for high-speed, lightweight, and dry-running work. They perform well where lubrication is minimal and corrosion is a concern.

- high-speed spindles, micro motors, and precision robotics
- corrosion resistance in harsh environments
- low friction and reduced heat in compact assemblies
- ideal for drones, cameras, and micro machines
