Describes the requirements for preprocessed silicon nitride materials for rolling bearing balls and rollers.

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 microstructures are provided in AnnexA.

NOTE1 The silicon nitride product means the sintered body of which the main component is silicon nitride material.

NOTE2 This document can be used for processed rolling bearing balls and rollers upon consultation between the parties concerned.
