IDENTI FICATION CODE 2.1 Ge
45、neral. This code identifies and, as far as possible, describes each needle roller bearing or component on the basis of complete dimen- sional and functional interchangeability. This code establishes a universal language for de- scribing and identifying bearings and compon- ents in order to facilitat
46、e communications between the user and the manufacturer. The code is also intended to simplify the handling by user personnel of identical bearings made by different manufacturers, whose identification numbers may be different and difficult to interpret. This code applies only to those radial needle
47、roller bearings or components whose boundary dimensions and tolerances conform to this standard. 2.2 Structure of Code. As shown in the following table, Schematic Arrangement of a Complete Code Number, the code consists of three sections. Section 1, called the Basic Number, includesa diameter symbol
48、 made up of a group of numerals, followed by a type symbol made up of a group of letters and finally by a dimension series symbol made up of a group of numerals. This Basic Number must always be used. Sections 2 and 3 delineate modification of design and lubricants and, if required to com- plete the identification, consist of additional letters. In the Schematic Arrangement Tables, “O” represents any code numeral and “A” represents any code letter. SCHEMATIC ARRANGEMENT OF A COMPLET
