前言

本标准非等效采用ISO2982–1∶1995《滚动轴承附件锥形衬套》。标准中补充了国际标准中没

有的技术条件。

本标准是对JB/T7919.2—95《滚动轴承附件紧定套基本尺寸》、JB/T7919.3—95《滚动轴承附

件紧定衬套基本尺寸》的修订，并部分代替JB/T7919.7—95《滚动轴承附件锥形衬套、锁紧螺

母和锁紧垫圈技术条件》。

本标准与JB/T7919.2—95、JB/T7919.3—95相比，主要作了以下修改：

——将JB/T7919.7—95的相关内容并入本标准中；

——扩大了紧定套H30、H31、H32系列及紧定衬套A30、A31、A32的尺寸范围，增加了H39系

列紧定套及A39系列紧定衬套；

——补充了大尺寸段的公差。

本标准自实施之日起代替JB/T7919.2—95、JB/T7919.3—95、JB/T7919.7—95（部分）。

本标准的附录A和附录B都是标准的附录。

本标准由全国滚动轴承标准化技术委员会提出并归口。

本标准起草单位：洛阳轴承研究所。

本标准主要起草人：陈原、郭宝霞、李飞雪。
