IS/ISO 12297 : Part 2 : 2018 Rolling Bearings - Cylindrical Rollers - Part 2 Boundary Dimensions, Geometrical Product Specifications (GPS) and Tolerance Values for Ceramic Rollers
NATIONAL FOREWORD
This Indian Standard (Part 2) which is identical to ISO 12297-2 : 2018 'Rolling bearings - Cylindrical rollers - Part 2: Boundary dimensions, geometrical product specifications (GPS) and tolerance values for ceramic rollers' issued by the International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on the recommendation of the Bearing Sectional Committee and approval of the Production and General Engineering Division Council.
This standard is published in two parts. Other part of the series is:
Part 1 Boundary dimensions, geometrical product specifications (GPS) and tolerance values for steel rollers
The text of ISO standard has been approved as suitable for publication as an Indian Standard without deviations. Certain conventions are, however, not identical to those used in Indian Standards. Attention is particularly drawn to the following:
a) Wherever the words 'International Standard' appear referring to this standard, they should be read as 'Indian Standard'; and
b) Comma (,) has been used as a decimal marker while in Indian Standards, the current practice is to use a point (.) as the decimal marker.
