Our ceramic bearings feature exceptional properties including high temperature resistance, cold resistance, wear resistance, corrosion resistance, magnetic electrical insulation resistance, oilless self-lubrication, and high-speed performance. These high-tech products are designed for extreme environments and specialized applications across multiple industries.
The rings and rollers utilize premium ceramic materials including zirconia (ZrO2), silicon nitride (Si₃N₄), silicon carbide (SiC), and aluminum oxide (Al₂O₃). Cages are constructed from advanced materials like PTFE, PEEK, UPE, PVDF, PA66, SUS304, and SUS316 for enhanced performance in demanding conditions.
- High Temperature Resistance: Operational range up to 220°C, significantly higher than standard bearings
- High Speed Capability: 1.5 times faster operation than conventional bearings due to low friction coefficient
- Extended Service Life: 2-3 times longer lifespan compared to standard bearings
- Electrical Insulation: Ideal for conductive environments due to ceramic's insulating properties
