La présente norme fait partie d'un ensemble de normes relatives aux rotules et embouts à rotule. Elle définit les dimensions d'encombrement et les tolérances des embouts de séries E et JK utilisées dans les articulations de type industriel.
This part of ISO 12240 specifies dimensions, tolerances and radial internal clearances for various dimension series of spherical plain bearing rod ends. The dimensions and tolerances specified in this part of ISO 12240 have been selected to permit the design and use of spherical plain bearing rod ends which incorporate radial spherical plain bearings having various sliding material combinations. The specified tolerance values apply for finished spherical plain bearing rod ends before any coating, plating, ring splitting or fracturing. Spherical plain bearing rod ends need not conform to the designs illustrated but compliance is required as regards dimensions, tolerances and radial internal clearances specified. NOTE — Spherical plain bearing rod ends for airframe applications and specific spherical plain baring rod ends for direct connection to hydraulic cylinders are not covered by this part of ISO 12240.
