Yunshuo full ceramic bearing
Key Advantages
*Complete Corrosion Immunity: Resists strong acids (HCl, H₂SO₄), alkalis, seawater, and organic solvents
*Exceptional Hardness: 1400-1600 HV hardness, 5-8x more wear-resistant than steel
*Non-Magnetic & Insulating: Zero magnetic response, resistivity >10¹² Ω·cm, suitable for MRI equipment
*Food/Medical Grade: FDA/EC1935 compliant, autoclavable
*Lightweight: 45% density of steel, reduces rotational inertia
