❓ FAQ — Silicon Nitride Ceramic Bearing Balls

Q: Why choose Si3N4 ceramic over steel?

A: It’s lighter, harder, corrosion-resistant, non-magnetic, and maintains strength at high temperatures — ideal for high-speed and sensitive applications.

Q: Can these run without oil?

A: Yes. They are self-lubricating and can operate under oil-free conditions where metal would fail.

Q: Are they suitable for electronics or MRI environments?

A: Absolutely — they’re non-magnetic and electrically insulating.

Q: How do I pick a size?

A: Match the OEM ball diameter and quantity. If upgrading from steel, keep the same nominal size for drop-in compatibility.
