💡 Why pick a full ceramic bearing over steel?
Because it handles what metal can’t:
- Won’t corrode in water, acids, or salt air
- Totally non-magnetic and non-conductive
- Requires no grease or oil to run smoothly

Reliable, silent, and built for tough conditions, this 4x10x4 zirconia ceramic bearing is small but unstoppable.
