Abstract
A universal joint bush for a universal joint of a universal joint shaft. In order to seal an annular gap, which is produced between the journal and the universal joint bush, a sealing ring is provided which encloses radially outwardly directed sealing lips. During assembly of the universal joint bush on the journal, the sealing lips, which are connected directly or indirectly to a radially inwardly directed rim of the universal joint bush, make a venting means possible, through which the air which is enclosed in the inner space of the universal joint bush can escape.
