NATIONAL FOREWORD

This Indian Standard (First Revision)which is identical with ISO 8443 : 2010 ‘Rolling bearings — Radial ball bearings with flanged outer ring — Flange dimensions’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 was first published in 1985 and has now been revised to align with the current ISO Standard ISO 8443 : 2010.

The text of ISO Standard has been approved as suitable for publication as an Indian Standard without deviations. Certain conventions and terminologies 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’.

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.
