前言

本标准是对JB2300—84《回转支承型式、基本参数和技术要求》的修订。

本标准与JB2300—84相比，技术内容方面改变如下：

——本标准增加了试验方法、检验规则、标志、包装、运输与贮存等内容，成为一个完整的产品标

准，故将标准名称改为《回转支承》；

——增加了一部分产品规格；

——对各种滚道型式回转支承的总成装配精度做了适当调整。

本标准自实施之日起代替JB2300—84。

本标准的附录A、附录B都是标准的附录。

本标准由工程机械标准化技术委员会提出并归口。

本标准起草单位：天津工程机械研究所、徐州回转支承公司、山东莱阳重型机械厂。

本标准主要起草人：徐向善、杜玉霞、罗霏、张明亮。

本标准于1984年12月20日首次发布。
