introduction

Due to the large number of parameter symbols and terminologies named in multiple ways in the field of sliding bearings, the interpretation of standards and technical documents

It is easy to cause misunderstanding in the process. This situation has caused the continuous increase of supplementary definitions and further aggravated the possibility of misunderstanding.

This part of GB/T 2889 aims to describe a unified abbreviation symbol system.

Plain bearing terms, definitions, classifications and symbols
