The 6206CE ceramic bearing has a bore diameter of 30 mm, an outer diameter of 62 mm, and a thickness of 16 mm; it is classified as a metric, small-to-medium-sized ceramic deep-groove ball bearing.
📐 Detailed Specifications
Dimensions: 30 mm (bore) × 62 mm (outer diameter) × 16 mm (thickness)—identical to the dimensions of a standard 6206 bearing.
Weight: Approximately 0.199 kg.
Dynamic Load Rating (Cr): 19,500 N (19.5 kN).
Static Load Rating (Cor): 11,300 N (11.3 kN).
Limiting Speed: Approximately 11,000 rpm for grease-lubricated open, Z, or ZZ types; approximately 7,500 rpm for versions with contact seals (RS/2RS); and approximately 13,000 rpm for oil-lubricated open types.
🔧 Materials and Characteristics
Material: Typically constructed as full-ceramic (zirconia, ZrO₂) or as a hybrid (ceramic balls with metal rings); some manufacturers also offer versions with silicon nitride (Si₃N₄) ceramic balls.
Key Advantages: High-temperature resistance (up to 300–800°C), corrosion resistance, resistance to acids and alkalis, non-magnetic, electrically insulating, and oil-free self-lubrication. Ideal for specialized environments such as vacuum, high-temperature, or corrosive settings.
Applications: Commonly used in high-temperature machinery, vacuum equipment, chemical pumps, electric motors, medical devices, etc.
