Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO
member bodies). The work of preparing International Standards is normally carried out through ISO technical
committees. Each member body interested in a subject for which a technical committee has been established has
the right to be represented on that committee. International organizations, governmental and non-governmental, in
liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical
Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3.
The main task of technical committees is to prepare International Standards. Draft International Standards adopted
by the technical committees are circulated to the member bodies for voting. Publication as an International
Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 104 was prepared by Technical Committee ISO/TC 4, Rolling bearings.
This third edition cancels and replaces the second edition (ISO 104:1994). The changes are editorial in order to
bring content, terminology and presentation in line with ISO Directives, Part 3, 1997.
Annex A of this International Standard is for information only.

INTERNATIONAL STANDARD
ISO 104:2002(E)
Rolling bearings — Thrust bearings — Boundary dimensions,
general plan
1
Scope
This International Standard specifies the major boundary dimensions of single-direction and double-direction thrust
bearings with flat back faces.
In addition, it gives the minimum bore diameters of housing washers and maximum outside diameters of shaft
washers of bearings in dimension series 11, 12, 13, 14, 22, 23 and 24.
Guidelines for the extension of this International Standard for single-direction thrust bearings are given in annex A.

Normative references
The following normative documents contain provisions which, through reference in this text, constitute provisions of
this International Standard. For dated references, subsequent amendments to, or revisions of, any of these
publications do not apply. However, parties to agreements based on this International Standard are encouraged to
investigate the possibility of applying the most recent editions of the normative documents indicated below. For
undated references, the latest edition of the normative document referred to applies. Members of ISO and IEC
maintain registers of currently valid International Standards.

General
The symbols shown in Figures 1 and 2 and the values given in Tables 1 to 9 denote nominal dimensions unless
specified otherwise.
The corresponding largest single chamfer dimensions to the rs min and r1s min dimensions in Tables 1 to 9 are given
in ISO 582. The exact shape of the chamfer surface is not specified, but its contour in an axial plane shall not be
allowed to project beyond an imaginary circular arc, of radius rs min, tangential to the washer back face and the
bore or outside cylindrical surface of the washer. For the washer face and the bore cylindrical surface, the same
applies to r1s min.
Chamfer dimensions r and r1 apply only at the corners indicated in Figures 1 and 2. No dimensions are given for
other corners, however, they should not be sharp.

Annex A
(informative)
Guidelines for the extension of this International Standard for
single-direction thrust bearings
A.1 General
For any new dimension not numerically determined in this International Standard, the following guidelines should
be used. The formulae given for outside diameter and height should not, however, be used for definite determination of the boundary dimension values; they may often require to be modified in order to maintain the continuity
of this International Standard to obtain suitable bearing proportions, and to permit selection of preferred dimensions.
Accordingly, any new dimensions will have to be approved by ISO.
A.2 Bore diameters
Bore diameters, d, of shaft washers, above d = 500 mm, should be selected from the R 40 series of preferred
numbers given in ISO 3.
A.3 Outside diameters
Outside diameters, D, of housing washers should be calculated, in millimetres, from the formula:
D = d + fD d
0,8
where the factor fD has the appropriate value given in Table A.1.
Table A.1 — Values of fD

Outside diameter dimensions already appearing in this International Standard should be chosen for preference.
New outside diameter dimensions should be rounded as shown in Table A.2.

A.4 Bearing heights
Bearing heights, T, should be calculated, in millimetres, using the formula:
T = fT
D−d
2
where the factor fT has the appropriate value in Table A.3
Table A.3 — Values of fT

Smallest single chamfer dimension rs min should be selected from the rs min values listed in ISO 582 and, in
principle, be that value which is nearest to, but not larger than the smaller of the two values: 7 % of the height T
and 7 % of the sectional width (D – d)/2.
