Zirconia Ceramic (ZrO2) Bearings
180°C Heat resistant · Acid resistant · Non-magnetic · Self-lubricating · Long life · High precision
Why Zirconia Ceramic Bearings
180°C Heat Resistant
Operating up to 180°C with PTFE cage; full-ball design up to 400°C.
Acid & Alkali Resistant
ZrO2 ceramic + PTFE cage withstands strong acids, alkalis, seawater.
Non-Magnetic & Insulated
Ideal for demagnetization equipment and precision instruments.
Self-Lubricating
No grease needed; reduced maintenance, longer service life.
Long Service Life
Higher hardness than steel; outperforms traditional steel bearings.
High Precision
Tight tolerances on inner/outer rings; low noise, low vibration.
Typical Applications
Chemical Processing
Equipment exposed to acids, alkalis, solvents.
Medical Devices
MRI, sterilization, biocompatible.
Food Machinery
FDA-grade, easy to clean, no grease contamination.
Marine & Offshore
Saltwater, corrosion resistance.
Semiconductor
Cleanroom, non-magnetic, particle-free.
High-Temperature
Ovens, kilns, 180°C+ continuous operation.
Demagnetization
Magnetic-free environment required.
Precision Instruments
Scales, measurement, low-vibration.
Salt-Spray / Saline
Coastal, desalination, harsh chemicals.
Frequently Asked Questions
What's the maximum operating temperature?
180°C with PTFE cage; full-ball design up to 400°C.
Can I hammer it during installation?
Yes. ZrO2 ceramic is tough — will not crack from normal handling.
Can I use it in a 2-wheel electric vehicle?
Not recommended. Ceramic bearings may crack under high-frequency vibration.
What industries commonly use ceramic bearings?
Chemical processing, medical devices, food machinery, marine, semiconductor, vacuum, and high-temperature equipment.
