  • Patent number: 6736731
    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).
