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) will be 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
