Rolling bearings. Ceramic bearing balls. Determination of strength by notched ball test Ingestion-build-100580 • Overload protection1 Scope This document specifies a method for the determination of the strength of finished ceramic balls for ball bearings, preferably made of silicon nitride (Si3N4), with ball diameters from 3 mm to 50 mm. NOTE 1 ISO 26602 specifies the requirements for preprocessed silicon nitride materials for rolling bearing balls. ISO 32902specifies requirements for finished silicon nitride balls for rolling bearings. NOTE 2 Other test methods to determine
