Ceramic Bearing Types and Specifications
Zirconia (ZrO2) All-Ceramic Bearing
Zirconia all-ceramic bearings feature anti-magnetic insulation, excellent wear and corrosion resistance, oil-free self-lubrication, and high temperature/cold resistance. They maintain dimensional stability between 100℃ to 600℃ and perform reliably in harsh environments including strong acids, strong alkalis, inorganic/organic salts, and seawater.
| Component | Materials |
|---|---|
| Inner And Outer Ring: | ZrO2 |
| Cage: | PTFE, PEEK, PA, UPE, SUS |
| Ball: | ZrO2, Si3N4, SSIC |
| Seal: | open, ZZ, 2RS |
Silicon Nitride (Si3N4) Ceramic Bearing
Silicon nitride ceramic bearings offer diamagnetic electrical insulation, superior wear and corrosion resistance, self-lubrication, and exceptional high-temperature performance. Suitable for temperatures from 100℃ to 800℃, they provide higher speed capacity and precision grades up to P4 for demanding applications.
| Component | Materials |
|---|---|
| Inner And Outer Ring: | Si3N4 |
| Cage: | PTFE, PEEK, PA, UPE, SUS |
| Ball: | Si3N4, SSIC |
| Seal: | open, ZZ, 2RS |
Hybrid Ceramic Ball Bearing
Hybrid ceramic bearings combine chrome steel or stainless steel rings with ceramic balls (ZrO2, Si3N4, or SiC). They deliver 1.5x higher speed capability and 2-3x longer service life compared to standard steel bearings, with enhanced temperature resistance.
| Component | Materials |
|---|---|
| Inner And Outer Ring: | SUJ2, SUS |
| Cage: | SUJ2, PA, SUS, bakelite |
| Ball: | ZrO2, Si3N4 |
| Seal: | open, ZZ, 2RS |
