    摘要: A cross member unit for universal joints has a cross member (6) with four arms (17). Each opposing two arms (17) define a common longitudinal axis 7. A bearing bush (9) is provided per arm (17) which covers the arm (17). Rolling contact members (29), in the form of a ring, are arranged in the intermediate space between the casing (23) of the bearing bush (9) and the cylindrical running face (19) of the arm (17). A preseal (38) is arranged towards the open end (27) of the bearing bush (9) between the arms (17) and the casing (23). To achieve a high running performance and a static sealing effect, the preseal (38), in its bore (40), is provided with beads (41, 42) which are firmly positioned on the seat portion (22) of the arm (17).

    摘要: Cross member units for universal joints have a cross member (6) with four arms (17). Each two opposing arms define a common longitudinal axis (7). A bearing bush (9), covering the arm (17), is provided per arm (17). In the space between the casing (25) of the bearing bush (9) and the cylindrical running face (19) of the arm (17), rolling contact members (32) are arranged in the form of a rim. Towards the open end (30) of the bearing bush (9), a preseal (44) and main seal (37) are arranged between the arms (17) and the casing (25). To achieve a high running performance and a maintenance-free assembly for storing lubricating grease, the arms (17) include a storage chamber (20) which is open towards its end face (18) and otherwise closed. The chamber is tapered, starting from the end face (18). Furthermore, the main seal (37) is secured to the bearing bush (9) by means of an externally positioned carrier (39) which projects beyond the open end of the bearing bush (9). The outer face of the carrier (39) serves to contact one of two seals (51, 52) of the preseal (44). The other sealing lip serves to contact a stop face (31) at the open end (30) of the bearing bush (9). The main seal also includes two continuous sealing lips (38, 38') for sealing purposes.
