A screw-nut screw coupling with ball circulation, in which the nut screw comprises at least one radial through bore, the surface of which embraces at least two adjacent turns of a circulation track for the balls. Each of said bores is engaged by a substantially cylindrical block which comprises at one end a diametrical groove for putting said two turns into communication, and is traversed by an axial bore which is closed externally by a removable element and is arranged to allow loading of the balls. These latter are loaded by supporting the screw and nut screw in a mutually coaxial position, and feeding the balls through the bore thereof while the screw is rotated relative to the nut screw. |
