NOTE 2 Depending on the application, bal
13、l screws are designed 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 IT
14、10 of ISO 286-1:1988. 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 lment
