Abstract
A method of producing a spherical joint () with a spherical sleeve () having a spherical bearing area () and provided with a through-going assembly opening that extends, in an axial direction (), which by virtue of the bearing area () is mounted and able to move by sliding in a spherical shell (). The spherical sleeve () is arranged in an outer sleeve () in such a manner that the spherical sleeve () extends outwardly, in an axial direction (), from both sides of the outer sleeve (). A material, which hardens, is injected into an intermediate space (), located between the spherical shell () and the outer sleeve (), such that when the material hardens, the assembly of the spherical sleeve () and the spherical shell () is joined to the outer sleeve ().
