Rolling bearings - Cast and pressed housings for insert bearings - Boundary dimensions and tolerances

This International Standard specifies boundary dimensions and tolerances for cast and pressed housings
for insert bearings for which boundary dimensions are given in ISO 9628[1].
It applies to plummer block housings, flanged housings and take-up housings.
The inclusion of relubrication features is optional, but when provided it is intended that they intersect the
zone specified in ISO 9628[1] in such a way that lubricant satisfactorily feeds from the housing through this
zone. The exact design of the relubrication features is not otherwise covered by this International Standard.

Roulements - Logements moulés et emboutis pour roulements "insert" - Dimensions d'encombrement et tolérances

L'ISO 3228:2013 sp�cifie les dimensions d'encombrement et les tol�rances des logements moul�s et emboutis pour roulements �insert� pour lesquels les dimensions d'encombrement figurent dans l'ISO 9628.
Elle est applicable aux corps de palier � semelle, de palier applique et de coulisseau tendeur.
L'inclusion de dispositifs de relubrification est facultative, mais lorsqu'ils sont stipul�s, il convient qu'ils imposent au lubrifiant de d�boucher sur la zone sp�cifi�e dans l'ISO 9628 de sorte que le lubrifiant soit correctement achemin� � partir du logement � travers cette zone. La configuration exacte des dispositifs de relubrification n'est pas donn�e dans l'ISO 3228:2013.

Kotalni ležaji - Uliti in stiskani okrovi za vgradnjo ležajev - Mejne mere in tolerance

Ta mednarodni standard določa glavne mere in tolerance za ulite in stiskane okrove
za vgradnjo ležajev, za katere so glavne mere navedene v ISO 9628[1]. Uporablja se za okrov stoječega ležajnega sklopa, okrov s prirobnico in okrov z napenjalno glavo. Vključitev funkcij ponovnega mazanja je neobvezna, kadar pa so zagotovljene, so namenjene preseku območja iz standarda ISO 9628[1], da se mazivo zadovoljivo dovaja iz okrova prek tega območja. Natančna konstrukcija funkcij ponovnega mazanja ni zajeta v tem mednarodnem standardu.

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 2.
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 document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 3228 was prepared by Technical Committee ISO/TC 4, Rolling bearings, Subcommittee SC 6,
Insert bearings.
This fourth edition cancels and replaces the third edition (ISO 3228:1993), which has been technically
revised. In particular, this fourth edition has been extended. Boundary dimensions and tolerances of cast
housings for diameter series 3 have been added in Tables 2, 4, 6 and 8. In addition, boundary dimensions
and tolerances of larger size cast flanged housings, oval and cast take-up housings for diameter series 2
have been added in Tables 5 and 7.

Avant-propos
L’ISO (Organisation internationale de normalisation) est une fédération mondiale d’organismes
nationaux de normalisation (comités membres de l’ISO). L’élaboration des Normes internationales est
en général confiée aux comités techniques de l’ISO. Chaque comité membre intéressé par une étude
a le droit de faire partie du comité technique créé à cet effet. Les organisations internationales,
gouvernementales et non gouvernementales, en liaison avec l’ISO participent également aux travaux.
L’ISO collabore étroitement avec la Commission électrotechnique internationale (CEI) en ce qui concerne
la normalisation électrotechnique.
Les Normes internationales sont rédigées conformément aux règles données dans les Directives
ISO/CEI, Partie 2.
La tâche principale des comités techniques est d’élaborer les Normes internationales. Les projets de
Normes internationales adoptés par les comités techniques sont soumis aux comités membres pour vote.
Leur publication comme Normes internationales requiert l’approbation de 75 % au moins des comités
membres votants.
L’attention est appelée sur le fait que certains des éléments du présent document peuvent faire l’objet de
droits de propriété intellectuelle ou de droits analogues. L’ISO ne saurait être tenue pour responsable de
ne pas avoir identifié de tels droits de propriété et averti de leur existence.
L’ISO 3228 a été élaborée par le comité technique ISO/TC 4, Roulements, sous-comité SC 6, Roulements «insert».
Cette quatrième édition annule et remplace la troisième édition (ISO 3228:1993), qui a fait l’objet et d’une
révision technique. La présente édition a notamment été étendue. Les dimensions d’encombrement et
tolérances des logements moulés pour les diamètres de la série 3 ont été ajoutés dans les Tableaux 2, 4,
6 et 8. De plus, les dimensions d’encombrement et tolérances pour les grandes tailles de corps de palier
applique moulé, ovale et les corps de coulisseau tendeur pour les diamètres de la série 2 ont été ajoutés
dans les Tableaux 5 et 7.

Roulements — Logements moulés et emboutis pour

1 Domaine d’application
La présente Norme internationale spécifie les dimensions d’encombrement et les tolérances des
logements moulés et emboutis pour roulements «insert» pour lesquels les dimensions d’encombrement
[1]
figurent dans l’ISO 9628 .
Elle est applicable aux corps de palier à semelle, de palier applique et de coulisseau tendeur.
L’inclusion de dispositifs de relubrification est facultative, mais lorsqu’ils sont stipulés, il convient qu’ils
[1]
imposent au lubrifiant de déboucher sur la zone spécifiée dans l’ISO 9628 de sorte que le lubrifiant soit
correctement acheminé à partir du logement à travers cette zone. La configuration exacte des dispositifs
de relubrification n’est pas donnée dans la présente Norme internationale.
