Zirconia (ZrO₂) and silicon nitride full ceramic bearings feature anti-magnetic and electrical insulation properties, excellent wear and corrosion resistance, and oil-free self-lubricating performance. With superior high and low temperature resistance, they support long-term operation within a temperature range of 100°C to 600°C without thermal expansion or deformation caused by temperature differences.
These bearings adapt to extremely harsh environments and special working conditions, including strong acids, strong alkalis, inorganic and organic salts, and seawater scenarios.
The races and rolling elements are made of high-performance zirconia (ZrO₂) ceramic as standard. The standard retainer adopts PTFE material. Multiple optional retainer materials are available to meet diverse working conditions, including glass fiber reinforced nylon 66 (GRPA66-25), special engineering plastics (PEEK, PI), stainless steel (AISI SUS316, SUS304) and brass (Cu).
