Abstract

An axial joint and a process for manufacturing an axial joint are described. The axial joint comprises a metallic housing (1) with an opening (2) and with an interior space (9), with a ball pivot (3), which has a joint ball (4) and a pivot pin (5). The joint ball (4) is surrounded for the most part by the housing (1) and a pivot pin neck (5.1) of reduced diameter compared with that of the pivot (5) is present in the transition area between the joint ball (4) and the pivot pin (5), and the pivot pin (5) projects through the opening (2) of the housing. The axial joint also has a bearing shell (6; 6.1, 6.2), which consists essentially of plastic and is arranged between the housing (1) and the joint ball (4), and the metallic housing is made in one piece.
