Si3N4 Full Ceramic Deep Groove Ball Bearing 6202CE – Ultimate Performance & Durability
High-purity silicon nitride (Si3N4) ceramic construction ensures superior corrosion resistance, extreme temperature stability (-200°C to +800°C), and electrical insulation—ideal for harsh environments like chemical processing, medical equipment, and aerospace. Precision-engineered with mirror-polished raceways and ceramic balls (Grade 5) for near-frictionless rotation, reducing energy loss by 40% vs. steel bearings. No lubrication needed for maintenance-free operation in high-speed applications (up to 30,000 RPM). Hybrid ceramic-steel design balances load capacity (radial: 1.2 kN, axial: 0.6 kN) with lightweight performance (60% lighter than all-steel bearings). Perfect for electric motors, robotics, and semiconductor machinery where weight and precision matter. Fully non-magnetic and anti-static, eliminating interference in MRI machines, lab instruments, and cleanroom automation. Direct OEM replacement for standard 6202 bearings—seamless integration without retrofitting. Global wholesale pricing available. Bulk discounts for industrial buyers. Stock ready for immediate shipment worldwide.
