Full Ceramic Ball Bearings with P6/ABEC3-P4/ABEC7 Precision
Our ceramic bearings feature high temperature resistance, cold resistance, wear resistance, corrosion resistance, magnetic electrical insulation, self-lubrication, and high-speed capabilities. These high-tech products are designed for extreme environments and specialized applications across multiple industries.
Material Composition
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.
Key Advantages
High Temperature Resistance: Operates up to 220°C (compared to 160°C for standard bearings)
High Speed Capability: 1.5× faster than conventional bearings
Extended Service Life: 2-3× longer lifespan than standard bearings
Electrical Insulation: Ideal for conductive environments
