Abstract

At least one end side (14,15) of the bearing (12) is provided between the shaft (10) and bearing (12) with a ring gap (17) whose expansion (16) reduces the capillary action so that the oil is fixed in the gap between the shaft and bearing. A radially expanding gap (24) can be provided between the end face of the bearing and a disc adjoining at least one of the end sides. The contact face between the disc (21) and a convex ring face formed coaxial with the bore (11) on at least one of the end faces of the bearing is kept to the smallest possible diameter. A centrifugal disc (25) can be seated fixed on the shaft (10) on the bearing side behind the disc (21).
