CORPORATE MATERIAL GUIDELINES FOR CODIFICATION OF ANTIFRICTION BEARINGS AT CORPORATE LEVEL The following guidelines formulated and recommended by the Working Group for Codification of Antifriction Bearings have been approved by the IPSC. This Code Catalogue has been worked out on this basis. 1. Corporate Code Numbers for Antifriction bearings shall be allotted under the main group 721. This group covers ball and roller bearings and also other types of bearings covered by specific standard series of reputed manufacturers. 2. Bearings used by more than one Division will be codified at the Corporate level irrespective of its value or number. The reserve code numbers for standard sizes which are prefixed could be allotted by the units with prefix AA. The units shall inform central standards Department of Corp. R&D, Hyderabad and other members of the Working Group (Bearings) about such allotments for recording in the master Code Catalogue. 3. Coding structure has been developed to identify each bearing on the basis of its boundary dimensions only and not taking into consideration variations in the design of bearing of different manufactures. 4. The code structure will cover all bearings used for production as well as for maintenance. Accessories of bearings like balls, rollers, adapter sleeves, withdrawal sleeves, etc. are also codified. 5. Metric bearings only are codified at corporate level. However, provision has been made in the coding Structure for inch bearings to facilitate plant level operation. 6. Corporate level size cods for metric bearings shall be operated from 01 to 80 and plant cods from 99 to 81 in descending order. 7. The code scheme shall cover normal clearance and zero precision bearings in a significant manner. Other grades and precision bearings are to be covered sequentially at the plant level only. 8. In addition to the codification of basic bearings, the structure also provides for combination of bearings and its accessories, such as lock nuts, locking washers, etc. 9. Normally Corporate code numbers with prefix AA only will be allotted. In the case of imported items, plants will take care of the prefixes suitably.

CORPORATE MATERIAL 10. Codification of the following tapered roller bearing in inch sizes is left to the individual plants as and when the sizes are required to be codified. This approval has been adopted due to the immensity by of the sizes of tapered roller bearings in inch sizes. a) 721 49 99 to 721 49 71 - Single row tapered roller bearings. b) 721 50 99 to 721 50 71 - Double row tapered roller bearings. c) 721 51 99 to 721 51 71 - Four row tapered roller bearings. d) 721 52 99 to 721 52 71 - Tapered roller thrust bearings. 11. Any bearing for which code number is existing either in the Corporate Material Code Catalogue or pre-coded numbering catalogue, can be directly allotted the corporate. code number against AA series by the 'User plants' and the same shall be intimated to Central Standards Department of Corporate R&D for registration of such codes in the master code catalogue. 12. The code catalogue enlists the reference of only one manufacturer or equivalent against each code. For equivalent of other manufacturers, please refer ' Equivalent Tables' issued separately. This is done merely to afford use of the existing format. 13. ISO designations, wherever applicable, shall be indicated. 14. Wherever possible two or three sub-classifications of bearing shall be accommodated under one major classification to ensure better utilization of the scheme. Eg.: AA 721 3 01 to AA 721 33 15 covers Single Row Needle And Single Thrust Ball Bearings and AA 721 33 16 onwards covers Double Row Needle And Single Thrust Ball Bearings. 15. Barred numbers of the check digit will also be used for code check digits. However, while operating the code numbers, the plants will take care of the correctness of the code numbers, since the computer will not point out the errors for the codes ending with barred check digits. These barred numbers shall be indicated with an asterisk mark(*) in the code catalogue. 16. The Corporate Code Catalogue shall have restricted circulation and distribution shall be controlled by the Standards Departments of the respective Divisions. 17. The unit of issue to be entered in the catalogue shall be numbers. 18. Unless otherwise amended or revoked by IPSC, the above guidelines shall hold good for codification of Antifriction Bearings in future also.
