ISO 121291 is the first part of the multi series of documents applicable to tolerances of plain bearings. ISO 121291 specifies a system of fits applicable to metallic plain bearings used in general engineering for mean relative bearing clearances, m, of 0,56 up to 3,15%. Note: This system of fits is not applicable to halfbearings and bushes
