A centered double universal joint has a first outer joint yoke (1) with first centering means (4, 6), a first inner joint yoke (8), a first cross member (10) connecting the first outer joint yoke (1) via rolling bearings (11) to the first inner joint yoke (8), and a first lubricant channel (44) for lubricating the rolling bearing (11). Also, the joint has a second outer joint yoke (12) with second centering mechanism (15, 17), a second inner joint yoke (19), and a second cross member (21) connecting the second outer joint yoke via rolling bearings (22) to the second inner joint yoke (19). A guiding disc (25) has a first central centering projection (28) articulatably connected to the first centering means (4, 6). The guiding disc has a second central centering projection (29) articulatably connected to the second centering means (15, 17). Guiding faces (32, 33) on the guiding disc (25) are radially adjustably guided in an annular recess (24) of a housing (9, 20). The first lubricating channel (44) is connected to a first lubricant guiding mechanism (50) of the first centering mechanism (4, 6). The guiding disc (25) has a lubricant channel (51, 53) which is connected to the first lubricant guiding mechanism (50) and ends in at least one of the guiding faces (32, 33).
