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of an identical text or by endorsement, at the latest by october 2004, and conflicting national standards shall be withdrawn at the latest by january 2006.this document has been prepared under a mandate given to cen by the european commission and the europeanfree trade association,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 standard en 1337 “structural bearings” consists of the following 11 parts:part 1general design rulespart 2sliding elementspart 3elastomeric bearingspart 4roller bearingspart 5pot bearingspart 6rocker bearingspart 7spherical and cylindrical ptfe bearings part 8guide bearings and restrain bearings part 9protectionpart 10inspection and maintenancepart 11transport, storage and installation annex a is normative and annex b is informative. this document includes a bibliography.according to the cen/cenelec internal regulations, the national standards organizations of the following countries are bound to implement this european standard: austria, belgium, cyprus, czech republic, denmark, estonia, finland, france, germany, greece, hungary, iceland, ireland, italy, latvia, lithuania, luxembourg, malta, netherlands, norway, poland, portugal, slovakia, slovenia, spain, sweden, switzerland and united kingdom.1scopethis part of en 1337 specifies the requirements for the design and manufacture of single and multiple roller bearings, 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 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 characteristic combination ofactions are outside the scope of this part of e
