Method for producing an extruded bearing journal

A method for producing an extruded bearing journal that extends in a longitudinal direction and has a lateral surface surrounding a longitudinal central axis of the bearing journal and has a face surface delimiting the bearing journal in an axial direction at a free end of the bearing journal, the method comprising:

• extruding the bearing journal in an extrusion tool by at least one extrusion punch;
• and
• reworking the bearing journal after said extruding step so as to improve the cylindricity of the bearing journal at least over a section of the longitudinal extent of the bearing journal, said reworking including:
• arranging the bearing journal, at least over a section of the longitudinal extent adjoining the free end thereof, into a cavity delimited in a radial direction of the bearing journal by a wall surface surrounding the lateral surface of the bearing journal,
• pressing a reworking punch that is moveable in the longitudinal direction of the bearing journal against the face surface of the bearing journal at the free end thereof so as to plastically deform the bearing journal and cause a flow of the material of the bearing journal, and
• pulling a sleeve off the bearing journal after the reworking punch has plastically deformed the bearing journal, wherein the reworking punch is pressed against the face surface of the bearing journal after the reworking punch has plastically deformed the bearing journal at least until the sleeve has been partially pulled off the bearing journal.
