10、 a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represen

ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are dr
12、afted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International S

NOTE 2 Depending on the application, ball screws are des
26、igned either with backlash or without backlash (preloaded). NOTE 3 To meet individual requirements six standard tolerance grades 0, 1, 3, 5, 7 and 10 are available. The tolerances for travel deviation are in accordance with the standard tolerance grades IT0, IT1, IT3, IT5, IT7 and IT10 of ISO 286-1:
27、1988. Usually standard tolerance grades 0 to 5 are preloaded, and grades 7 and 10 are not preloaded. 2.1.1.1 vis billes assemblage dune vis, dun ou plusieurs crous billes et de billes, capable de transformer un mouvement de rotation en mouvement linaire et vice versa NOTE 1 Les lments roulants de la
