BRIEF HISTORY
The IS0 Recommendation R 464, Rolling Bearings. Bearings with Locating Snap Ring.
Dimensions, was drawn up by Technical Committee ISO/TC 4, Rolling Bearings, the Secretariat
of which is held by the Sveriges Standardiseringskommission (SIS).
This 1SO Recommendation cancels and replaces section 4 of the IS0 Recommendation
R 15-1955, Ball and Roller Bearings.
Work on this question by the Technical Committee began in 1956 and led, in 1962, to the
adoption of a Draft IS0 Recommendation.
In October 1962, this Draft IS0 Recommendation (No. 360) was circulated to all the IS0
Member Bodies for enquiry. It was approved by the following Member Bodies:
Australia France Romania
Germany Spain
Austria
Belgium Hungary Sweden
Brazil India Switzerland
Bu 1 gar i a Ireland United Kingdom
Burma Italy U.S.A.
Japan U.S.S.R.
Canada
Chile Netherlands Yugoslavia
Czechoslovakia New Zealand
No Member Body opposed the approval of the Draft.
The Draft 1SO Recommendation was then submitted by correspondence to the IS0
Council, which decided, in December 1965, to accept it as an IS0 RECOMMENDATION.
