Abstract: An axial retaining arrangement for a bearing bushing in a bearing bore, forming a bore wall, of a yoke arm of a joint yoke belonging to a universal joint or of a bearing element by means of a retaining ring, wherein the bearing bushing has an outer face, with which it rests in the bearing bore, the bearing bore forms a longitudinal axis, the bore wall of the bearing bore or the outer face of the bearing bushing have an annular groove centered on the longitudinal axis, the retaining ring has a first ring portion, retained in the annular groove, has at least one second ring portion following to the first ring portion, which is elastic in the radial direction and which at least forms one engagement edge, which, depending on the arrangement of the annular groove to the bearing bore or the bearing bushing is pressing against the bore wall or the outer face.

Abstract: A cross member unit for universal joints has a cross member (6) with four trunnions (17). Each two trunnions define a common longitudinal axis (7). Each trunnion (17) has an end face (18), a first sealing face (21) and a pre-sealing face (24). The pre-sealing face (24) is remote from the end face 18 and has a diameter increasing relative to the first sealing face (18). A bearing bush (9) is on each trunnion (17). Each bearing bush (9) has an open end 29 and has rolling contact members 27 rotatably supporting the trunnion (17) around the longitudinal axis (7) of the trunnion (17). An annular seal (30) is provided in each bearing bush 9. The annular seal (30) is held in the bearing bush 9 by a press fit. The annular seal (30) includes an annular carrier (31) which projects from the open end (29) of the bearing bush (9). The annular seal includes at least one first sealing lip (35) which is in contact with the first sealing face (18) of the trunnion (17). The annular seal has a pre-seal (38) in the form of a sealing lip or bead which is in contact with the pre-sealing face (24) of the trunnion 17. An end face (32) is on the carrier (31). The end face (32) is remote from the end face (18) of the trunnion (17). An annular gap (26) is formed between the end face (32) and a radial face (40) of a shoulder (39) of the trunnion (17).
