BRIEF HISTORY
The IS0 Recommendation R 355, Rolling Bearings. Tapered Roller Bearings, Boundary
Dimensions, Part ZZ, was drawn up by Technical Committee ISO/TC 4, Rolling Bearings, the
Secretariat of which is held by the Sveriges Standardiseringskomission (SIS).
Work on this question by the Technical Committee began in 1958 and led, in 1961, to the
adoption of a Draft IS0 Recommendstion.
In January 1963, this Draft IS0 Recommendation (No. 472) was circulated to all the IS0
Member Bodies for enquiry. It was approved by the following Member Bodies:
Australia
Greece Spain
Austria
Hungary Sweden
Belgium India Switzerland
Canada Italy Turkey
Chile Japan United Kingdom
Czechoslovakia Netherlands U.S.S.R.
France
Poland Yugoslavia
Germany Romania
No Member Body opposed the approval of the Draft.
The Draft IS0 Recommendation was then submitted by correspondence to the IS0 Council,
which decided, in December 1965, to accept it as an IS0 RECOMMENDATION.

f
d = bearing bore diameter
D = bearing outside diameter
B = inner ringwidth
T = bearing width* (width over bearing rings)
r = chamfer dimension** (height and width) on inner and outer ring back faces
rI = 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.
