Abstract
In a method for producing an extruded bearing journal, the bearing journal is extruded in an extrusion tool by means of at least one extrusion punch and, after the extrusion of the bearing journal, reworking of the bearing journal is performed in order to improve the cylindricity of the bearing journal at least over a section of the longitudinal extent of the bearing journal. During the reworking, the bearing journal is arranged, at least over a section of its longitudinal extent adjoining its free end, in a cavity that is delimited in a radial direction of the bearing journal by a wall surface surrounding the lateral surface of the bearing journal, and a reworking punch which is movable in the longitudinal direction of the bearing journal is moved toward the free end of the bearing journal and is pressed against the face surface of the bearing journal and, in this way, a plastic deformation of the bearing journal, with a flow of material of the bearing journal, is effected.
