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°C to 600°C and perform reliably in harsh environments including strong acids, strong alkalis, inorganic/organic salts, and seawater.
Material Configuration
| Inner & 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 more severe conditions and higher ambient temperatures (100°C to 800°C), they provide high-speed capability, precision accuracy (up to P4 grade), and enhanced rigidity for demanding applications.
Material Configuration
| Inner & 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 offer low density, high hardness, low friction coefficient, anti-magnetic properties, wear resistance, and excellent rigidity. Compared to standard steel bearings, hybrid versions achieve up to 1.5x higher speeds and 2-3x longer service life.
Product Configuration
| Inner & Outer Ring | SUJ2, SUS |
|---|---|
| Cage | SUJ2, PA, SUS, Bakelite |
| Ball | ZrO₂, Si₃N₄ |
| Seal | Open, ZZ, 2RS |
