BRIEF HISTORY
The IS0 Recommendation R 355, Part III, Rolling bearings - Tapered roller bearings - Boun-
dary dimensions - Metric series: Diameter series 9 and O, was drawn up by Technical Committee
ISO/TC 4, Rolling bearings, the Secretariat of which is held by the Sveriges Standardiserings-
kommission (SIS).
Work on this question by the Technical Committee began in 1953 and led, in 1963, to the
adoption of a Draft IS0 Recommendation.
In July 1964, this Draft IS0 Recommendation (No. 594) was circulated to all the IS0
Member Bodies for enquiry. It was approved, subject to a few modifications of an editorial
nature, by the following Member Bodies :
Austria Hungary Romania
Brazil India Spain
Canada Israel Sweden
Chile Italy Switzerland
Czechoslovakia Netherlands U.A.R.
France Poland United Kingdom
Germany Portugal Yugoslavia
Two Member Bodies opposed the approval of the Draft:
Japan
U.S.S.R.
The Draft IS0 Recommendation was then submitted by correspondence to the IS0 Council,
which decided, in April 1967, to accept it as an IS0 RECOMMENDATION.

.
d = bearing bore diameter
D = bearing outside diameter
B = inner ring width
T = bearing width * (width over bearing rings)
r
= chamfer dimension * * (height and width) on inner and outer ring back faces
rl = chamfer dimension ** (height and width) on inner and outer ring front faces
* Attention is called to the fact that the cage may project beyond the bearing width.
** Nominal chamfer dimensions do not control the shape of the bearing corner.
