•  Ceramic balls are spherical, rolling elements that provide higher stiffness, lower thermal expansion, lighter weight, increased corrosion resistance, and higher electrical resistance than steel balls. They are made from a variety of ceramic materials.

•  CLI Bearing provide a wide range of ceramic ball options across a variety of sizes. Material options include Silicon nitride (Si3N4), Zirconia (ZRO2), Alumina (Al2O3) and Silicon carbide (SIC) from 0.4mm to just over 115mm in diameter with the most common sizes in between. Precision grades provided are G5, G10, G16, G25 and G100 grades.

•  Different ceramic material have different properties, here is the introduction of ceramic materials and their properties.
