ISO 26602:2017规定了滚动轴承球和滚柱用预处理氮化硅材料的要求。 ISO 26602:2017提供了定义氮化硅预处理轴承滚动体材料物理和机械性能的分类。根据特性和微观结构的规格，材料分为三类。附录A中提供了样品制备和微观结构观察方法。 注1:氮化硅产品指主要成分为氮化硅材料的烧结体。 注2:ISO 26602:2017可用于相关方协商后加工的滚动轴承球和滚柱。

ISO 26602:2017 specifies the requirements for preprocessed silicon nitride materials for rolling bearing balls and rollers. ISO 26602:2017 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 Annex A. NOTE 1 The silicon nitride product means the sintered body of which the main component is silicon nitride material. NOTE 2 ISO 26602:2017 can be used for processed rolling bearing balls and rollers upon consultation between the parties concerned.
