15、0000551 785 FOREWORD (This foreword is not part of ANSVAFBMA Standard 18.2, Needle Roller Bear- ings - Radial, Inch Design.) This Standard comprises a revision of those portions of ANSVAFBMA Std. 18.2-1976, Inch Design Radial Needle Roller Bearings, which relate to Inch De- sign Product. All materia
16、l which relates only to Metric Design Product will be found in Standard 18.1. Most of the Table numbers have been changed. Using the numbering se- quence in this standard, major changes have been made to Tables 4.1 and 5.7. Minor changes have been made to most of the other Tables. The material in th
17、is standard conforms, where possible, to recommendations of the International Standards Organization, Technical Committee 4, Rolling Contact Bearings, in whose work the U.S.A. has actively participated through delegates officially appointed by the American National Standards Institute. Copies of IS0
18、 Recommendations concerning Rolling Contact Bearings (Ball and Roller Bearings) are available from the American National Standards Insti- tute, Inc., 1430 Broadway, New York, N.Y. 10018. Suggestions for the improvement of this standard gained through experience with its use will be welcomed. These s
19、hould be sent to the American National Standards Institute, Inc., 1430 Broadway, New York, N.Y. 10018. The officers of Sectional Committee B3 of the American National Standards Institute and the organizations represented at the time this standard was sub- mitted are as follows: S. R. Ahlman, Chairma

41、tting and Mounting Practice Airframe Needle Roller Bearings, Needle Roller Thrust Bearings, and bearings of other types are covered in separate AFBMA-ANSI Standards. D 2. IDENTIFICATION CODE 2.1 General. This code identifies gnd, as far as possible, describes each needle roller bearing or component
42、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 facilitate communications between the user and the manufacturer. The code is also intended to simplify the handl
43、ing 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 rol ler bearings or components whose boundary dimensions and tolerances conform to this standard. 2.2 S
44、tructure 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, includes a diameter symbol made up of a group of numerals, followed by a type symbol made up of a group of letters and finally
45、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 a
46、ny code numeral and “A“ represents any code letter.
