This document specifies methods of calculating the dynamic load ratings for hybrid bearings with bearing rings made of contemporary, commonly used, high quality hardened bearing steel, in accordance with good manufacturing practice and rolling elements made from silicon nitride in contemporary, commonly used, high material and manufacturing quality and surface finish. For balls, ISO26602[6] together with ISO3290‑2[2] are applicable. For rollers, ISO12297‑2[3] is applicable and ISO26602[6] is applicable in an analogous way.
