IS 3824 : 2014/ISO 281 : 2007 Rolling Bearings - Dynamic Load Ratings and Rating Life (Third Revision)

NATIONAL FOREWORD

This Indian Standard (Third Revision) which is identical with ISO 281 : 2007 ‘Rolling bearings - Dynamic load ratings and rating life’ 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 1966 and subsequently revised in 1983 and 2002. This revision is now being taken up to align with the latest version of ISO 281.

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

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.
