ISO 4378-1:2009给出了与滑动轴承的设计、轴承材料及其特性有关的最常用术语及其定义和分类。对于一些术语和单词组合，给出了简短的形式，可以在明确的地方使用。自解释的术语没有定义。 除了三种ISO官方语言中的英语和法语中使用的术语外，ISO 4378-1:2009还提供了德语中的等效术语；这些文件由德国标准协会（DIN）成员机构负责发布，仅供参考。只有官方语言中给出的术语和定义才能被视为ISO术语和定义。

ISO 4378-1:2009 gives the most commonly used terms relating to design, bearing materials and their properties of plain bearings with their definitions and classification. For some terms and word-combinations, the short forms are given, which can be used where they are unambiguous. Self-explanatory terms are given without definitions. In addition to terms used in English and French, two of the three official ISO languages, ISO 4378-1:2009 gives the equivalent terms in German; these are published under the responsibility of the member body for German (DIN), and are given for information only. Only the terms and definitions given in the official languages can be considered as ISO terms and definitions.
