Zirconia (ZrO2) all-ceramic bearings feature exceptional performance characteristics including anti-magnetic insulation, wear resistance, corrosion resistance, oil-free self-lubrication, and high/low temperature tolerance.
- Minimal thermal expansion between 100°C to 600°C
- Suitable for harsh environments including strong acids, strong alkalis, inorganic/organic salts, and seawater
- Rings and rolling elements manufactured from zirconia (ZrO2) ceramic materials
- Standard PTFE protectors with optional materials including fiberglass-reinforced nylon 66 (GRPA66-25), specialized engineering plastics (PEEK, PI), stainless steel (AISI SUS316, SUS304), and brass (Cu)
