High-precision ceramic sphere used as rolling element in ceramic hybrid bearings for demanding industrial applications.
A ceramic sphere is a precision-engineered spherical component manufactured from advanced ceramic materials, primarily silicon nitride (Si3N4) or zirconia (ZrO2), designed to serve as the rolling element in hybrid ceramic bearings. These spheres exhibit exceptional hardness, corrosion resistance, and thermal stability, making them suitable for high-speed, high-temperature, and chemically aggressive environments where traditional steel balls would degrade.
