GQZ 6206-2RZTN9/HC5C3WT Hybrid Ceramic Deep Groove Ball Bearing 30×62×16mm

6206-2RZTN9/HC5C3WT is high-performance single row hybrid ceramic deep groove ball bearing (SKF standard designation).

• 2RZ: Double-sided non-contact NBR rubber seals, dust-proof, retain internal grease
• TN9: Snap-type PA66 glass fiber reinforced polyamide cage
• HC5: Hybrid structure, steel rings + silicon nitride (Si₃N₄) ceramic balls, electrically insulated
• C3: Increased radial internal clearance
• WT: Special high-speed long-life lithium complex grease

It withstands radial load plus minor bidirectional axial load. Ceramic rolling elements block electric current erosion (bearing electric corrosion), deliver higher speed limit, lower friction, lighter weight and better thermal stability. Pre-greased, maintenance-free for long-cycle continuous operation. Widely used on variable frequency motors, servo motors, high-speed spindles, generators, wind power auxiliary equipment and high-speed rotary units vulnerable to electric arc damage.
