Fine ceramics (advanced ceramics, advanced technical ceramics). Silicon nitride materials for rolling bearing balls and rollers Ingestion-build-100998 BS EN 60027-4 on rotating1 Scope This document specifies the requirements for preprocessed silicon nitride materials for rolling bearing balls and rollers. This document provides a classification defining physical and mechanical properties of silicon nitride preprocessed bearing rolling element materials. The materials are classified in three categories by the specification of characteristics and microstructures. Methods for sample preparation and observation of
