21、, the secretariat of which is held by UNI. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by October 2004, and conflicting national standards shall be withdrawn at the latest by January 2006. This d
22、ocument has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EU Directive(s). For relationship with EU Directive(s), see informative annex ZA, which is an integral part of this document. The European

27、rings, in which the roller axis is horizontal. In order to accommodate displacements parallel to the roller axis roller bearings can be combined with sliding elements in accordance with EN 1337-2. To permit rotation about the axis perpendicular to the roller axis or about both axes, as for multiple
28、roller bearings, the roller bearings can be combined with bearings from other parts of EN 1337. This part of EN 1337 does not apply to roller bearings made with materials other than those specified in clause 5. Bearings which are subjected to rotation greater than 0,05 rad resulting from the charact
29、eristic combination of actions are outside the scope of this part of EN 1337. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text, and the publications
