Introduction
Due to the existence of a large number of parameter symbols and terminology named in multiple ways in the field of sliding bearings, in the interpretation of standards and technical literature
It is very easy to cause misunderstandings in the process. This situation has caused the continuous increase of supplementary definitions and further exacerbated the possibility of misunderstandings.
The purpose of this part of GB/T 2889 is to establish a unified, basic structure for explaining the structure, bearing materials and properties of sliding bearings
Nomenclature system.
