Features
Premium Ceramic ZrO2/Si3N4 Deep Groove Ball Bearings – Unmatched Durability & Precision
Engineered with high-grade zirconia oxide (ZrO2) and silicon nitride (Si3N4) for superior corrosion resistance, extreme temperature tolerance (-200°C to +800°C), and 60% lighter than steel bearings. Ideal for high-speed applications like dental drills, aerospace components, and electric vehicle motors.
Ultra-Low Friction & Maintenance-Free
Advanced ceramic materials reduce friction by 40% vs. metal bearings, enabling smoother rotation and 3x longer lifespan. Self-lubricating design eliminates grease contamination—perfect for food processing, medical devices, and cleanroom environments.
Precision-Ground for High RPM Performance
Laser-calibrated grooves and polished ceramic balls ensure ±0.001mm tolerance. Supports 50,000+ RPM (RS seals for dust/fluid protection). Trusted in CNC spindles, robotics, and turbochargers.
