scope:

This document gives guidelines to calculate the static 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 of ceramic, usually silicon nitride (Si₃N₄) in contemporary, commonly used material and manufacturing quality. It contains no normative provisions.

When using hybrid bearings the reduced static load ratings and the recommendations for the static safety factor according to DIN ISO 76 in comparison to conventional rolling bearings shall be observed.
