Not for Resale UJ IS0 IS0 6626-2:1994(E) Introduction IS0 8826 bearings provides rules for the simplified representation of rolling The principle of drawing practice is to depict the object to scale using lines In simplified representations, only essential features are shown, preferably in outline (in order to save time and effort) The degree of simplification depends on the kind of object represented, the scale of the drawing and the purpose of the documentation This means that either a general simplified representation or a detailed one may be used A detailed representation shows more details of rolling bearings, for example the number of rows or the possibility of alignment In order to avoid misunderstandings, the general or the detailed simplified drawing only one kind of simplification, either representation, should be used on a `,,`,-`-`,,`,,`,`,,` -
