Ceramic Bearings
Silicon Nitride (Si3N4) and Zirconia hybrid/full ceramic bearings for extreme speed.
Advanced hybrid ceramic bearings (steel rings with Silicon Nitride Si3N4 balls) and full ceramic bearings (Zirconia ZrO2 or Si3N4 rings and balls). Designed for extreme speeds, high temperatures, electrical insulation, and corrosive chemical immersion.

Specifications
Technical profile
- Construction
- Hybrid (52100/SS rings + Si3N4 balls) or Full Ceramic (ZrO2 / Si3N4 throughout)
- Ball material
- Hot Isostatically Pressed (HIP) Silicon Nitride (Si3N4) — grade G5 precision
- Cage options
- PEEK, PTFE, Full Complement (no cage), or High-Temp Phenolic
- Max Speed
- Up to 50% higher RPM rating than steel bearings due to 40% lower ball weight
- Temperature
- Up to 300 °C (Hybrid with PEEK cage) / up to 800 °C (Full Si3N4 without cage)
- Electrical property
- 100% electrical insulator — prevents EDM current fluting in VFD motor bearings
- Corrosion resistance
- Full ceramic models operate submerged in acids, alkalis, and seawater without rust

Key benefits
Why this product
- Total electrical insulation eliminates VFD-induced electrical bearing fluting in AC motor drives
- Si3N4 ceramic balls are 60% lighter and 50% harder than steel, reducing centrifugal ball skidding at high RPM
- Can operate completely dry without grease or oil lubrication in vacuum and cleanroom environments
- Extends bearing service life by 5× to 10× in demanding semiconductor, pharma, and chemical pumps
