💡 Why are full ceramic ZrO2 ball bearings used in demanding applications?
Full ceramic zirconia ball bearings are chosen when standard steel bearings cannot handle the environment.

• Zirconia ceramic resists corrosion, moisture, and chemicals

• Full ceramic construction provides electrical insulation and non-magnetic behavior

• PTFE cage supports smooth rotation with reduced friction

• Sealed design helps extend service life in clean or harsh settings

A smart option when you need a clean-running, corrosion-resistant bearing that stays smooth and reliable in tough operating conditions.
