Abstract

A method for the assembly of universal joints with radially pretensioned fork arms, consisting of the steps of inserting and positioning the joint cross in the joint fork, pressing in the bearing and fixing them by means of pressure units, one of which supports each fork arm and pretensioning each fork arm individually during the entire pressing-in and/or fixing phase by means of the tipping force resulting from the pressure prevailing between the support element and the pressing/peening tool, reduced by a partial force following in response to the amount of the pressing force.
