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